Store batteries in a cool, dry place and avoid extreme temperatures. Regularly clean the battery contacts and avoid depleting the battery completely before recharging.

Regularly inspect the tool for wear and tear. Clean the tool after each use, and conduct a thorough inspection every 6 months, checking for loose screws and worn parts.
