Common symptoms
- BATTERY SEATS BUT WILL NOT STAY LATCHED
- Battery loses charge rapidly while stored disconnected
- Battery repeatedly overheats or protection-stops during light use
- Battery becomes unusually hot during an otherwise normal charge
- The GBA18V40 starts onto the receiver rails but binds before reaching the normal seated and latched position.
- The battery reaches the normal seated position, but the release latch does not retain it and the pack can slide away without pressing the release button.
- BATTERY WILL NOT SLIDE FULLY INTO A COMPATIBLE TOOL OR CHARGER
- The pack is fully seated, the release button is pressed, and the battery still cannot be slid out without excessive force.
