VI. Maintenance
Battery Care and Storage
- Avoid overcharging and over-discharging. Recharge the battery when its level is below 20%.
- For long-term storage, keep the battery with 40%-60% charge.
- Do not store for extended periods in high-temperature environments.
- To activate a new battery, perform repeated charge and discharge cycles (e.g., 3-5 times). Each discharge should not exceed 70% of the capacity to stabilize the battery voltage.
VII. Troubleshooting
Common Issues
- Q1: What should I do if the battery cannot be charged?
A: Check the charger, power connection, and whether the battery is damaged. - Q2: Why does the battery life become shorter?
A: It may be due to an increased number of charge cycles or exposure to high environmental temperatures. - Q3: Is it normal for the battery to get warm during use or charging?
A: Slight heating is normal. However, stop using the battery immediately if it becomes excessively hot or overheats.
