Power tools and their battery packs: guards, vents, matching an accessory to the tool, hearing protection, and the storage that decides how long a lithium-ion pack lasts.
Common failure modes
- A pack stored fully discharged over a winter
- A pack charged or stored outside its temperature range
- Vents blocked with dust, which overheats the motor
- A guard removed and not replaced
- An accessory rated below the tool's no-load speed
Procedures
No procedure is published in this section yet. New procedures are added as their specifications can be traced to a manufacturer or government source.
Where this stops
Motor, switch and mains lead repair are deferred. A speed rating or an arbor size always comes from the tool and the accessory manufacturer, never from this site.
