What to do when a cordless tool battery looks damaged

Stop using or charging a pack that shows physical damage, leaking, smoke or unusual heat. Check the manufacturer’s safety instructions and available recall information for its exact model.

Independent reference. ToolBattery is not a manufacturer or authorized service center. Model revision, region, condition and the latest manual may change the answer. Do not use an unapproved adapter or modified battery.

Separate a routine delay from damage

A charger may pause for a hot or cold pack, but a damaged enclosure or abnormal heat calls for a different response. Do not keep retrying a questionable pack to force a charge.

Identify the exact model

Record the battery and charger model numbers from their labels. Manufacturer instructions and recall notices apply to specific products or serial ranges, not all batteries of a brand.

Use an official resolution path

Contact the manufacturer or authorized service channel for examination, replacement or disposal guidance. Do not open a lithium-ion pack, bypass protection electronics, or follow unverified jump-start procedures.
