According to a study by the Institute of Electrical and Electronics Engineers (IEEE), using smart chargers that adjust charge levels based on battery conditions can enhance battery life significantly.
Proper Storage:
Proper storage is also critical for battery longevity. Batteries should be stored in a cool, dry place away from direct sunlight or extreme temperatures. If a battery will not be used for an extended period, it should be periodically charged to prevent deep discharge. The Battery Council International advises that stored batteries should be checked every few months to ensure they remain in good condition and are not losing charge.

By considering these factors in battery maintenance, users can significantly enhance performance and extend the service life of their batteries.
