Operating Instructions
Proper initial charging is crucial for activating the battery's full capacity and ensuring long-term performance.
- Initial Charge Cycle: After replacing the battery, fully discharge the battery until the device powers off. Then, fully charge it without interruption. Repeat this full discharge and full charge cycle 3-5 times to activate the battery's full capacity.
- Charging: Always use the original charger and data cable provided with your radio to charge the battery. Using incompatible chargers may damage the battery or affect its performance.
- Normal Use: Once activated, the battery is ready for normal operation. The 1350mAh capacity provides extended standby and usage time.
Maintenance and Care
Following these guidelines will help prolong the life and maintain the performance of your battery.
- Optimal Charge Level: To prevent a decrease in chemical activity and maintain battery performance, it is recommended to keep the battery level within the range of 20% - 80%. Avoid consistently discharging the battery below 20% or keeping it at 100% for extended periods.
- Avoid Overheating: Prolonged use under high load, such as playing games while charging, can cause the battery to overheat and accelerate aging.
- Long-Term Storage: If the battery will not be used for an extended period, charge it regularly (e.g., once every 3 months) to maintain its activity and prevent damage from natural discharge. Store in a cool, dry place.

Troubleshooting
- Battery Not Charging: If the battery does not appear to charge, it may have entered a self-protection mode during transportation. Try charging the battery for up to 10 hours using a high-power charger. If a high-power charger is not available, use the original charger. This process can reactivate the battery.
