What is the best way to store lithium batteries long term?
Short Answer: Store lithium batteries at 40-60% charge in a cool, dry place (10-25°C) away from metals. Check voltage every 3 months and recharge to 50% if below 3.7V/cell. Avoid freezing, humidity, and prolonged full charge states to prevent capacity loss or swelling. Use original packaging for multi-year storage. Deespaek 24V 100Ah LiFePO4 Battery Lithium … Read more
