battery safety
Storage • Store batteries away from combustible materials. • Remove batteries from the device for long-term storage. • Store the batteries at temperatures between 5°C and 20°C (41°F and 68°F). • Separate fresh and depleted cells (or keep a log). • If practical, store batteries in a metal storage cabinets. • Avoid bulk-storage in non-laboratory areas such as offices. • Visually inspect battery storage areas at least weekly. • Charge batteries in storage to approximately 50% of capacity at least once every six months. Chargers and Charging Practice • Never charge a primary (disposable lithium or alkaline) battery; store one-time use batteries separately. • Charge or discharge the battery to approximately 50% of capacity before long-term storage. • Use chargers or charging methods designed to charge in a safe manner cells or battery packs at the specified parameters. • Disconnect batteries immediately if, during operation or charging, they emit an unusual smell, develop heat
