Likely Root Causes

- Battery release button or latch is jammed, cracked, or not returning
- Handle rails or battery-interface housing are damaged

Repair Preview

- Inspect the pack case, rails, latch, release button, and saw rails for debris, swelling, cracks, heat damage, or bent plastic.
- Clean the rails dry, align the pack squarely, slide until it latches, or press the release fully and pull the pack straight out.
- - Compare with a known-good compatible pack - if the tool rails, latch, release, or housing remain damaged or jammed, keep the saw out of service for authoriz
