Buying Guide

Match voltage and platform

Confirm the pack voltage and connector type match your tool platform to ensure safe compatibility and proper power delivery

Choose the right chemistry

Select lithium-ion for higher energy density and lighter weight, or Ni‑MH when vintage tool compatibility is required

Consider amp-hour (Ah) capacity

Higher Ah numbers give longer runtime per charge, so pick higher capacity packs when run-time matters

Check weight and size

Compact, lightweight packs improve tool balance and reduce user fatigue for handheld applications

Look for genuine-brand vs replacement

Branded packs aim for OEM fit and safety features; reputable replacements can be cost-effective but require compatibility checks
