Use the appropriate charging practices: Avoid using quick charge modes often, as these can generate excess heat and stress the battery. A report by the Journal of Power Sources (Huang et al., 2020) suggests that using regular charging rates helps maintain the longevity of batteries. Charging at lower temperatures can also help minimize the risk of overheating.
-
Store batteries properly: If not in use, store lithium batteries in a cool, dry place with about 50% charge. This storage method minimizes self-discharge and chemical degradation. Research from the Journal of Energy Storage (Moussa et al., 2021) shows that storing batteries at partial charge rather than full charge significantly enhances lifespan.
-
Avoid physical stress: Do not expose lithium batteries to impacts or excessive vibrations. Such physical stress can lead to internal damage, which can reduce the battery’s efficiency. A thorough analysis published in the Journal of Electrochemical Society (Wang et al., 2022) indicates that physical shocks can compromise cell integrity.
By following these practices, you can significantly extend the life of your lithium batteries and improve their overall performance.
