Power Tool Batteries

What do I need to know before buying replacement power tool batteries?

  • Is the battery compatible with your tool? This includes the brand, the battery chemistry (Li-ion/NiMH/NiCd) and the voltage. It is also important to check the battery connector, as tools from the same manufacturer sometimes have different connectors.
  • What battery capacity do you require? This is measured in amp-hours (Ah) and refers to the runtime of the battery, i.e. how many tasks you can complete on one charge. The higher the capacity, the longer the runtime.

What are the advantages of Lithium-ion power tool batteries?

Cordless Tool Batteries

  • Excellent power-to-weight ratio
  • No memory effect: you do not need to completely discharge the battery before recharging it
  • Low self-discharge: the battery retains its charge for longer when not in use
  • No lazy battery effect
  • Able to withstand lower temperatures in working order for more flexible working and storage
