Power tool batteries

The platform is the product

Cordless batteries lock into a brand, voltage family and physical interface. Choose the ecosystem before collecting packs.

Power tool battery buying guide

Voltage identifies the tool platform and must match. Amp-hours describe charge capacity within that platform: a higher-Ah pack can usually run longer, but adds size and weight and must still be approved for the tool.

  • Compare the full tool range, charger options and battery sizes before buying into an ecosystem.
  • Genuine packs offer known cell sourcing, battery-management communication, warranty support and matched chargers.
  • Third-party packs vary widely. Avoid counterfeit logos, implausible capacity claims, damaged cases or chargers that are not independently safety certified.
  • Stop using any pack that is swollen, cracked, wet, unusually hot or has damaged terminals.
One ecosystemShared batteries reduce duplicate chargers and idle packs.
Compact packsLower Ah can reduce weight for drills and overhead work.
High-capacity packsUseful for saws and outdoor tools, with more weight.
