Proper storage of your Black and Decker 20V Lithium Battery can make a big difference in its lifespan and performance. Many users overlook how important it is to keep the battery at the right temperature when not in use. During summer, avoid leaving it in hot garages or cars, as extreme heat can damage the cells. In winter, cold environments like outdoor sheds can also reduce battery efficiency. The ideal storage place is a cool, dry area indoors where temperatures stay moderate. It’s best to store the battery partially charged, around 40–60%, rather than fully drained or fully charged. Keeping it in a clean, dust-free space also helps protect the contacts. Avoid exposure to moisture or direct sunlight to prevent long-term damage. If you won’t be using the battery for several months, check and recharge it occasionally. Following these simple storage practices ensures that your Black and Decker 20V Lithium Battery stays reliable year-round.
