Battery families are summarized as ranges or families as published by the maker; the platform sections below list the sizes in full. Tool counts are the makers' claims, attributed — where the file behind this page found no published count, the cell says “Maker doesn't publish a count” rather than borrowing a retailer's number.

• Same voltage platform only. Greenworks states it flatly in its FAQ: “Our batteries are interchangeable with tools that are of the same voltage platform only” — a 40V pack never runs a 60V or 80V tool, even within the same brand. Treat that as the default rule for every platform on this page.
• Sibling brands share nothing by default. DeWalt, Craftsman, Black+Decker and Porter-Cable are all Stanley Black & Decker brands with 20V-class systems, but no maker states their packs interchange — assume they do not. The same applies to the TTI siblings (Milwaukee, Ryobi, Ridgid, Hart) and the Chervon siblings (EGO, SKIL, FLEX).
• Verified bridge — DeWalt FLEXVOLT. One FLEXVOLT pack runs both 20V MAX and 60V MAX tools, and two packs together run 120V MAX tools. It is a one-way bridge: ordinary 20V MAX packs cannot run 60V MAX tools.
• Verified bridge — Metabo HPT MultiVolt. One pack auto-switches between voltages and runs both 18V and 36V tools, and it is backward-compatible with older Hitachi 18V slide-style tools.
• Verified bridge — Makita 18V X2. Bigger LXT tools run on two ordinary 18V LXT packs to make 36V. No new battery to buy.
• Verified bridge — Worx Power Share. Everything is built from the 20V pack: 40V tools take two, 80V tools take four.
• Verified bridge — Bosch AMPShare. One 18V interface shared across brands: Bosch Professional packs also run AMPShare partner brands' tools, and vice versa. It is the only multi-brand alliance here founded by a maker.
• Charging-only bridges (the packs still don't swap on tools): Makita's ADP10 adapter lets XGT chargers charge LXT batteries; Milwaukee sells M12 + M18 dual-voltage chargers; Ryobi sells an 18V/40V Dual Platform Charger (PCG007); Makita's DC18RE charges CXT (12V) and LXT (18V) packs.
• Corded escape hatches: Metabo HPT's 36V tools also accept the ET36A AC adapter, so the tool can run plugged in. DeWalt's legacy 18V tools are reported to accept 20V MAX packs via DeWalt's DCA1820 adapter (unverified) — the adapter's existence is reported by secondary guides and was not verified against dewalt.com in this research.
• Cross-brand adapters: third-party adapters and “universal” packs exist for most brand pairs, but no tool maker endorses them — they sit between two battery-management systems never designed to talk to each other. They are mentioned here so you know they exist; they are not recommended as a supported way to mix platforms.

Voltage: 56V. EGO is an outdoor-only brand (Chervon) — there are no EGO drills; the platform is the lawn line. Battery sizes as published: 2.5, 4.0, 5.0, 6.0, 7.5, 8.0, 10.0 and 12.0Ah (the 6.0Ah ships in the T6 riding tractor kit). Tool count: EGO's own Powered by EGO site says the 56V ARC Lithium battery “drives 100+ EGO tools” — retailer copy of EGO product descriptions says “all 80+ EGO tools,” so treat the count as EGO's marketing figure, not a census.

Compatibility (verified): EGO's FAQ — “Are EGO batteries compatible with all EGO Products? Yes… it will fit any tool” — and its chargers likewise fit any EGO battery. EGO UK: “All our batteries are interchangeable across the entire EGO cordless garden tool range.” Multi-battery tools (the Z6 zero-turn mower, the T6 tractor, two-stage snow blowers) use Peak Power to combine several packs at once. Outdoor line: the whole platform — walk mowers, the Z6 zero-turn, the T6 riding tractor, string trimmers, blowers, chainsaws, hedge trimmers, snow blowers and the Nexus power station, where the packs double as a power source.

Voltage: 18V (TTI; Home Depot in North America). Battery sizes as published: 1.5, 2.0, 4.0, 6.0, 8.0 and 12.0Ah — including HIGH PERFORMANCE packs and the 4.0Ah EDGE tabless pack. Tool count: Ryobi claims “over 300 innovative products” on ONE+, and markets “30 years of battery compatibility” (the system launched in 1996).

Compatibility (verified): “With 30 years of battery compatibility, RYOBI 18V ONE+ batteries are compatible with any RYOBI 18V ONE+ product” — today's packs still run ONE+ tools back to 1996, per Ryobi. A reported 2026 renaming of the battery tiers (High Performance → “18V ONE+ Lithium”; HP EDGE → “Lithium EDGE”) is (unverified) against ryobitools.com and cosmetic in any case; fit is unchanged. Outdoor line: one of the largest — ONE+ mowers, trimmers, blowers, chainsaws and snow blowers all share the same 18V packs as the drills, which is Ryobi's big selling point against its own 40V line.

Voltage: 40V MAX (36V nominal), outdoor-only. Battery sizes as published: 2.0, 4.0, 6.0, 8.0 and 12.0Ah, plus EDGE (tabless) 4.0 and 8.0Ah. Tool count: Maker doesn't publish a count — Ryobi states no single platform count in the sources checked (its outdoor page lists roughly 125 products in the 40V category, but that is a store listing, not a claim).

Compatibility (verified): Ryobi's standard product copy: “Part of the RYOBI 40V System – Any 40V Battery Works With Any 40V Product.” 40V packs do not run 18V ONE+ tools and vice versa — they are separate platforms; the only bridge is the 18V/40V Dual Platform Charger (PCG007), which charges both families. Outdoor line: the whole platform — mowers, snow blowers, chainsaws, trimmers, blowers, the Expand-It attachment system and power sources/inverters.

Voltage: 80V, outdoor-only — riding and zero-turn mowers and a 1,000W power source. Battery sizes as published: a 14.0Ah pack (OP8014BCA) is listed on ryobitools.com; the full range is (unverified) in this research. Tool count: Maker doesn't publish a count.

Compatibility (verified): 80V is its own Ryobi platform, separate from 40V and 18V ONE+ — Ryobi sells the three as distinct systems. An explicit Ryobi non-compatibility statement was not captured in this research, so treat cross-use as not supported.

Voltage: a compact 4V-class system that Ryobi markets by name, not voltage — screwdrivers, rotary tools, power scrubbers, fans, glue pens and pruning shears. Battery sizes as published: 2.0Ah (FVB02) and 3.0Ah (FVB03). Tool count: Maker doesn't publish a count.

Compatibility (verified): USB Lithium batteries “Power the RYOBI USB Lithium System” and are interchangeable across USB Lithium tools. The distinctive rule: the packs charge by USB-C cable (the port is on the pack) and can in turn charge mobile devices — no proprietary charger needed.

Voltage: 18V (TTI). Battery sizes as published: standard REDLITHIUM 2.0, 4.0 and 5.0Ah; HIGH OUTPUT 3.0, 6.0, 8.0 and 12.0Ah; and the FORGE XC8.0 and HD12.0 tabless flagship packs. Tool count: Milwaukee claims M18 is “fully compatible with over 200+ solutions” on its product pages.

Compatibility (verified): all M18 packs run all M18 tools — Milwaukee's product pages state the packs are compatible with all M18 tools and the tools are “part of the M18 system.” Milwaukee does not claim M12↔M18 tool compatibility; the crossover is charger-level, via M12/M18 multi-voltage chargers. A separate pro platform, MX FUEL, exists for large equipment and does not share M18 packs. Outdoor line: M18 FUEL outdoor equipment — blowers, trimmers, chainsaws, QUIK-LOK attachments and a mower — runs on the same M18 packs.

Voltage: 12V — a sub-compact system for tight spaces, plus heated gear and compact outdoor tools. Battery sizes as published: 2.0, 3.0, 4.0 and 6.0Ah; HIGH OUTPUT CP2.5 and XC5.0. Tool count: Milwaukee claims in its current press releases that “the M12 System is made up of more than 150 solutions,” billed as “the largest sub-compact system on the market.”

Compatibility (verified): within M12 only. Milwaukee makes no claim of M12 packs running M18 tools (the rails differ); dual-voltage chargers are the bridge. Outdoor line: small but real — for example, the M12 FUEL 8″ hedge trimmer launched as part of the M12 system.

Voltage: 20V MAX (18V nominal — see the label explainer above). Battery sizes as published: 1.3, 2.0, 4.0, 5.0, 6.0 and 8.0Ah standard/XR; POWERSTACK pouch-cell 1.7, 3.5 and 5.0Ah; and XR tabless (“Powerpack”) 4.0 and 8.0Ah. Tool count: DeWalt claims its FLEXVOLT batteries are “compatible with 60V MAX* and 300+ 20V MAX* system tools” — DeWalt's own figure for the 20V MAX system is 300+.

Compatibility (verified): all 20V MAX packs fit all 20V MAX tools. DeWalt's 12V MAX is a separate footprint and does not interchange with 20V MAX tools; many DeWalt chargers charge both 12V and 20V packs (charging only). Outdoor line: 20V MAX outdoor tools — trimmers, blowers, chainsaws, mowers — share the platform with the drills; heavier outdoor gear sits on FLEXVOLT 60V, next.

Voltage: dual-voltage — the pack detects the tool and switches. Battery sizes as published: DCB606 — 6.0Ah in a 20V tool / 2.0Ah in a 60V tool; DCB609 — 9.0Ah / 3.0Ah; DCB612 — 12.0Ah / 4.0Ah. Compatibility (verified, dewalt.com): the FLEXVOLT battery “powers 60V MAX DEWALT tools and is also backwards compatible to work with 20V MAX DEWALT tools,” and DeWalt's copy also states FLEXVOLT packs are “Compatible with All 20V MAX, 60V MAX and 120V MAX Tools” — two FLEXVOLT packs together power 120V MAX tools such as the cordless miter saw.

Outdoor line: 60V MAX FLEXVOLT outdoor tools — chainsaws, trimmers, blowers, mowers — run on these packs, and the same packs drop back into 20V MAX drills.

Voltage: 18V slide-style packs. Battery sizes as published: 1.5Ah (BL1815N), 2.0Ah (BL1820B), 3.0Ah (BL1830B), 4.0Ah (BL1840B), 5.0Ah (BL1850B) and 6.0Ah (BL1860B), per Makita's own battery/charging compatibility chart. Tool count: Makita claims LXT is “the world's largest compatible cordless tool system powered by 18V slide-style batteries,” with “over 350 solutions.”

Compatibility (verified): all LXT packs run all LXT tools. 18V X2 (36V) tools — mowers, chainsaws, blowers, rotary hammers — run on two 18V LXT packs inside the same system; there is no separate 36V battery to buy. LXT packs do not run XGT tools (see the next entry). Outdoor line: a full LXT outdoor range plus the Outdoor Adventure sub-line, all on the same packs as the drills.

Voltage: 40V max (36V nominal); two packs together power Makita's 80V max tools. Battery sizes as published: 2.0Ah (BL4020), 2.5Ah (BL4025), 4.0Ah (BL4040 / BL4040F High Power), 5.0Ah (BL4050F) and 8.0Ah (BL4080F / BL4080H High Power). Tool count: Makita claims (Equip Expo 2026 press release) that “the expanding XGT System will offer 170+ 40V and 80V max cordless tools and equipment in 2026.”

Compatibility (verified): XGT is a stand-alone system — LXT and XGT batteries are not cross-compatible (different voltage and terminal design; in Makita's stated position, “LXT and XGT batteries are not cross compatible. Each platform has been designed to stand-alone.”). The only bridge is charging: the ADP10 adapter lets XGT chargers (DC40RA etc.) charge LXT batteries — charging only; it does not let an LXT pack run an XGT tool. Outdoor line: XGT carries Makita's heaviest outdoor equipment — large chainsaws, power cutters and 80V max two-pack tools. Makita's ConnectX backpack power supply is stated by Makita to work with XGT and 18V X2 LXT equipment via adapters.

Voltage: 18V — Bosch's professional “blue” line. Battery sizes as published: GBA 18V 2.0, 4.0 and 5.0Ah; ProCORE18V 4.0, 5.5, 8.0 and 12.0Ah; EXPERT tabless EXBA18V-40 (4.0Ah) and EXBA18V-80 (8.0Ah). Tool count: Bosch claims its 18V system plus the AMPShare alliance spans “over 430+ tools” on a starter-set product page; another Bosch page says “over 350+ tools” — Bosch's own pages differ, so both figures are Bosch's, from different pages.

Compatibility (verified): “All Professional 18V batteries and chargers have been fully compatible since 2008” — a 2026 Bosch ProCORE pack runs a 2008 Bosch Professional tool. AMPShare is the multi-brand alliance Bosch founded: partner brands build tools on the same 18V battery interface, so one brand's AMPShare pack runs another brand's AMPShare tool — the only maker-backed cross-brand system in this guide. Bosch's separate 12V professional system does not interchange with 18V. Bosch's consumer “Power for All 18V” line (green, mostly European) is a different line from Bosch Professional and is not merged into this entry.

Voltage: 24V. Battery sizes as published: 2.0Ah (including HP), 3.0Ah (USB-C), 4.0Ah (USB-C) and 6.0Ah — newer packs add USB-C ports (they charge phones, and some charge by USB-C too). Tool count: Greenworks claims the 24V POWERALL platform “powers 200+ indoor & outdoor products” and that its batteries are “Compatible with 200+ Greenworks 24V Tools.” An earlier Greenworks release said “over 125 products” — the 200+ figure is the current one.

Compatibility (verified): all Greenworks 24V packs run all Greenworks 24V tools (“This [tool] can be used with all Greenworks 24V battery models”); nothing crosses to 40V, 60V or 80V, per Greenworks' FAQ rule that batteries interchange only within the same voltage platform.

Voltage: 40V, outdoor-only. Battery sizes as published: 2.0Ah verified on greenworkstools.com; the wider sold range is (unverified) in this research. Tool count: Greenworks claims its product copy “Power 75+ Tools with Greenworks 40V Battery.”

Compatibility (verified): same-voltage-platform only (Greenworks' FAQ); one charger serves all 40V packs regardless of amp-hours (maker FAQ).

Voltage: 60V — outdoor tools plus Greenworks' e-transportation line. Battery sizes as published: 8.0Ah (model 2957102) verified; the full range is (unverified) in this research. Tool count: Greenworks claims in a press release that the 60V platform powers “over 75 indoor and outdoor products.”

Compatibility (verified): same-platform only (maker FAQ) — with the maker-documented exception below. “Fits the system” still has footnotes: this one is about the pack's physical height, not its connector.

Voltage: 80V, outdoor-only and pro-leaning. Battery sizes as published: 2.5Ah verified on greenworkstools.com; the wider range is (unverified) in this research. Tool count: Greenworks claims its battery page is “Compatible with 75+ Greenworks Pro 80V tools.”

Compatibility (verified): same-platform only (maker FAQ) — with the documented legacy exception below.

Greenworks' own release lists five Greenworks platforms — 24V, 40V, 60V, 80V and 82V. The 82V platform is Greenworks Commercial's OPTIMUS line, a separate sibling to Pro 80V: its packs are not stated to fit 80V tools, and no compatibility with the 80V platform is claimed. Battery sizes and a tool count for 82V were not published in the research behind this page, so neither is stated here.

Voltage: 60V MAX, outdoor-only (Toro makes no drills on it). Battery sizes as published (Ah / Wh, Toro's own chart): 2.0 (108Wh), 2.5 (135Wh), 4.0 (216Wh), 5.0 (270Wh), 6.0 (324Wh), 7.5 (405Wh), 8.0 (432Wh) and 10.0 (540Wh). Tool count: Toro claims the packs are “Part of the Toro 60V Max* interchangeable 75+ tool Flex-Force Power System.”

Compatibility (verified, toro.com): “The removable batteries are interchangeable with every 60V Max* Flex-Force tool.” Toro's 60V is a closed, Toro-only system. Outdoor line: the whole platform — walk mowers, snow blowers, string trimmers, blowers and chainsaws.

Voltage: 20V MAX (Stanley Black & Decker). Battery sizes as published: standard V20 packs of 1.5, 2.0, 4.0, 5.0 and 6.0Ah, plus the V20 ADVANCED tabless packs — 3.0Ah (CMCB2103) and 6.0Ah (CMCB2106), launched May 2026. Tool count: Stanley Black & Decker claims in its ADVANCED launch release that the packs work with “the full line of existing CRAFTSMAN V20* tools, spanning over 100 different products from power tools to outdoor equipment.”

Compatibility (verified): the new ADVANCED packs are “Compatible with existing CRAFTSMAN V20* tools” — the platform fit has not changed across battery generations — and V20 covers power tools and outdoor equipment on the same packs. No maker states that V20 packs fit DeWalt or Black+Decker tools despite the shared parent company; do not assume it. Craftsman's V60 outdoor line is (unverified) in this research.

Voltage: 24V Max (Lowe's house brand). Battery sizes as published: 2.0 through 8.0Ah, including the “Ultimate Output” top tier. Tool count: Maker doesn't publish a count — Lowe's publishes no platform count in the sources checked.

Compatibility (verified, Lowe's/Kobalt product copy): 24V batteries are “Compatible with all Kobalt 24-volt max cordless power tools,” and the starter kit is “Fully compatible with the entire Kobalt 24V system.” XTR high-performance tools stay backward-compatible with all 24V Max batteries. The platform covers power tools and outdoor tools.

Emerging, flagged as the research flags it: Lowe's is launching Kobalt 24Vx2 (48V Max) outdoor tools that pair two 24V packs, kitted with USB-chargeable batteries and reportedly developed with Greenworks. Whether standard 24V Max packs fit the new tools is (unverified) — no claim is made here either way.

Voltage: 40V Max (36V nominal), outdoor-only. Battery sizes and tool count: (unverified) in this research — Maker doesn't publish a count in the sources checked, and no size list is stated here rather than guessed.

Compatibility (verified, Lowe's product copy): bare tools are “compatible with all Kobalt 40V Max batteries.” The 40V line is a separate platform from 24V and 80V — Lowe's sells the three as distinct battery platforms.

Voltage: 80V, outdoor-only — mowers, blowers and edgers. Battery sizes as published: a 2.5Ah pack appears in Lowe's listings; the full range and the tool count are (unverified) in this research — Maker doesn't publish a count in the sources checked.

Compatibility: the 80V line is sold as its own platform, separate from Kobalt 24V and 40V (Lowe's platform copy); no cross-platform compatibility is claimed by Lowe's.

SKIL (Chervon) sells three families under the PWRCore name. SKIL does not state that packs cross between the families — treat them as not interchangeable (flagged honestly: that is unverified as an explicit maker statement, because no SKIL cross-voltage claim exists at all). Tool counts: Maker doesn't publish a count for any of the three families.

PWRCore 12 — 12V compact tools; packs 2.0 and 4.0Ah (retail listings). SKIL's copy: batteries are “Compatible with all SKIL 12V tools in the PWRCORE 12 system.” Some PWRCore 12 packs have USB-C ports and can charge from ordinary USB-C blocks. PWRCore 20 — 20V; packs 2.0, 4.0 and 5.0Ah (retail listings). SKIL's copy: the battery/charger is “compatible with all SKIL tools in the PWRCore 20 family.” It powers power tools and SKIL outdoor tools such as chainsaws. PWRCore 40 — the 40V outdoor platform; packs 2.5, 4.0, 5.0 and 6.0Ah (retail listings).

Verified exception: SKIL sells a 12V/20V drain cleaner that accepts either a PWRCore 12 or a PWRCore 20 pack — a rare deliberate dual-voltage tool, and the exception that proves the families otherwise stay apart.

Voltage: 24V (Chervon; Lowe's) — every FLEX tool is 24V. Battery sizes as published: standard lithium-ion 2.5, 5.0, 8.0 and 12.0Ah; Stacked Lithium (pouch-cell) 2.0, 3.5, 6.0 and 10.0Ah. Tool count: Maker doesn't publish a count.

Compatibility (verified): FLEX's platform principle is full cross-compatibility within the brand — “FLEX 24V CROSS-COMPATIBILITY — Compatible with all FLEX 24V batteries, chargers, and tools.” Standard cylindrical packs and Stacked Lithium pouch packs interchange across all FLEX 24V tools (Stacked packs unlock full output on high-demand tools). FLEX packs fit nothing else — a unique rail, and FLEX states they are not backward-compatible with other platforms. Outdoor line: FLEX sells 24V outdoor tools (blowers and more) on the same packs; there is no separate outdoor voltage.

Voltage: 20V (TTI; Walmart). Battery sizes as published: 1.5, 2.0, 4.0 and 5.0Ah seen in Hart's line. Tool count: Maker doesn't publish a count.

Compatibility (verified, harttools.com): “our 20V system allows all your 20V batteries to work with all your 20V tools” — “The HART 20V battery system allows you to interchange the same battery between all 20V HART products.” The system covers power tools, outdoor equipment, automotive and lifestyle products: the yard tools share packs with the drills.

Voltage: 40V, outdoor-focused. Battery sizes and tool count: (unverified) in this research — Maker doesn't publish a count in the sources checked.

Compatibility: Hart's 20V and 40V are separate systems — “The 20V batteries won't work in the 40V products and vice versa” (Pro Tool Reviews, secondary). No Hart statement of cross-use exists.

Voltage: dual-voltage MultiVolt packs, plus ordinary 18V-only packs. Battery sizes as published: BSL36A18 — 8.0Ah in an 18V tool / 4.0Ah in a 36V tool; BSL36A18X — 5.0Ah / 2.5Ah. (The amp-hours halve at 36V because the same energy is delivered at twice the voltage.) Tool count: Maker doesn't publish a count.

Compatibility (verified, metabo-hpt.com): the MultiVolt battery “POWERS: All Metabo HPT 18V and 36V tools,” and from the tool side, 18V tools “Accept any 18V battery or 18V/36V MultiVolt battery.” MultiVolt packs are also backward-compatible with older Hitachi 18V slide-style tools. And 36V MultiVolt tools can run corded via the ET36A AC adapter — the only battery/corded hybrid here.

Voltage: a 20V-based building-block system (Positec) — 20V tools take one pack, 40V tools take two, 80V tools take four. Battery sizes as published: standard and PRO packs from 2.0 to 8.0Ah, including the verified 4.0Ah Power Share PRO (WA3674) and the 8.0Ah pack (WA3678). Tool count: Worx claims its packs are “compatible with 140+ Worx cordless products.”

Compatibility (verified, worx.com — the maker's words): Power Share PRO batteries “are 100% compatible with all WORX 20V, 40V, 80V tools, outdoor power, and lifestyle products that display the POWER SHARE or POWER SHARE PRO logo.” The same packs run drills, outdoor tools and Landroid robotic mowers.

Voltage: 20V MAX (Stanley Black & Decker). Battery sizes as published: 1.5, 2.0, 3.0 and 4.0Ah — Black+Decker describes “lightweight options of 1.5Ah to 2Ah or opt for 3Ah to 4Ah.” Tool count: Maker doesn't publish a count.

Compatibility (verified, blackanddecker.com): the POWERCONNECT system is “the same interchangeable battery” across Black+Decker 20V MAX products — and it spans both DIY power tools and lawn & garden tools on one pack, which is this platform's selling point.

Voltage: 18V (TTI; Home Depot). Battery sizes as published: 2.0, 4.0, 6.0Ah and the 8.0Ah MAX Output EXP. Tool count: Maker doesn't publish a count.

Compatibility (verified, Ridgid product copy via Home Depot): “100% Compatible: Works with all RIDGID 18V Tools and Chargers.” The platform's hallmark is the Lifetime Service Agreement (with registration) covering tools and batteries — a buying angle no other platform here matches. Outdoor line: a modest 18V outdoor range shares the packs.

Voltage: 56V, outdoor-only and professional-leaning (ECHO / Yamabiko). Battery sizes as published (Ah / Wh): 2.5 (126Wh), 5.0 (252Wh) and 8.0 (402Wh), per ECHO specifications via dealer listings. Tool count: Maker doesn't publish a count.

Compatibility (verified, ECHO product copy via dealers): eFORCE batteries are “Compatible with all ECHO eFORCE tools and chargers” — with the one maker-stated exception below, which is why ECHO describes the 5.0Ah pack as compatible with “most” eFORCE products.

AS system — compact handheld tools (pruners, shrub shears) with the small AS 2 battery; a system of its own, separate from AK and AP. AK system — 36V, the homeowner line; packs AK 10, AK 20, AK 30 and AK 30 S, running AK mowers, trimmers, blowers and chainsaws. AP system — 36V, the professional line; packs AP 100, AP 200, AP 300, AP 300 S and AP 500 S, plus the AR backpack batteries (AR 1000 / 2000 / 3000) worn on the back for long runtime, which belong to the AP system. STIHL's new ALLPRO tabless packs are fully compatible with AP system tools. Tool counts: Maker doesn't publish a count for any of the three systems.
