Extending the life of a lithium-ion battery requires careful handling and maintenance. Here are some tips to maximize its longevity:
1. Avoid Complete Discharges
- Try not to fully discharge your battery to 0% unless necessary. Partial discharges are better for longevity.
- Keep the battery level between 20% and 80% when possible to reduce stress on the battery.
2. Limit Full Charges
- Avoid keeping your battery at 100% charge for extended periods, as this also stresses the battery.
- Partial charges (up to 80%) are recommended for daily use.
3. Optimize Charge Voltage
- Reducing the charge voltage can increase cycle life but may decrease capacity. Optimal charge voltage for longevity is around 3.92V/cell.
4. Control Temperature
- Store and operate batteries in cool environments (between 32°F and 95°F) to prevent overheating, which accelerates degradation.
- Charging at high temperatures (like 131°F or 55°C) can enhance lifespan by improving the solid-electrolyte interphase (SEI).
5. Avoid Fast Charging
- Use fast charging sparingly as it generates heat, which can shorten battery life.
6. Store Properly
- Store unused batteries at a charge level of 40-50% in a dry place to minimize degradation.
7. Monitor and Maintain
- Periodically charge batteries to prevent deep discharges during storage.
- Perform maintenance cycles (charge to 100%, discharge to low, then recharge to 50%) every 6-12 months for unused batteries.
