Maintaining the health of lithium-ion batteries involves careful charging habits. Here are some guidelines:
- Charge Levels and Frequency:
- Lithium-ion batteries should ideally be charged when they drop to 20-30% capacity. Regular full depletion is not recommended as it reduces the battery’s lifespan.
- Maintaining charge levels between 20% and 80% is generally considered optimal for battery health.
- Full Charge Cycles:
- It is not necessary to fully charge lithium-ion batteries. Charging to 80% is sufficient for most purposes and helps reduce stress on the battery.
- Allow a full discharge and recharge cycle (from 0% to 100%) only occasionally, such as once a month, to calibrate the battery meter.
- Maintenance Cycles:
- For stored lithium-ion batteries, perform a maintenance cycle every six months. This involves charging to 100%, discharging fully, and then charging back to 50% to maintain capacity.
- Storage Conditions:
- Store lithium-ion batteries at a capacity of approximately 50% if they will be unused for extended periods. Keep them in a cool, dry place (between 5°C and 20°C).
- Avoid Overcharging:
- Avoid leaving batteries on charge for extended periods beyond full capacity, as this can lead to overheating and stress on the battery.
Following these guidelines helps extend the life of lithium-ion batteries and maintains their overall health.
