- Discharge Issues: If your battery shows signs of swelling or heat, it’s best not to use it. These issues indicate potential failure, so replace it immediately.
- Store Batteries Properly: If you have spare batteries, store them in a cool, dry place. Proper storage extends battery life and prevents leaks.
Following these safety precautions ensures a smooth battery replacement and minimizes risks associated with handling lawn mower batteries.
