Proper storage is key to keeping your Black and Decker 20V Lithium Battery in top condition. Always store the battery in a cool, dry place away from direct sunlight or excessive heat. Extreme temperatures can reduce its performance and shorten its lifespan. Avoid leaving the battery inside a car or damp areas like basements. When storing for a long period, keep the battery charged at around 40–60% rather than fully drained or completely charged. This helps preserve the lithium cells inside. It’s also smart to remove the battery from tools when not in use to prevent accidental discharge. Keep it in its original case or a protective bag to avoid dust and moisture exposure. Never store near flammable materials or metal objects that could cause a short circuit. By following these simple storage practices, your Black and Decker 20V Lithium Battery will stay reliable, safe, and ready whenever you need it.
