Precautions

1. No Memory Effect: Lithium batteries do not have a memory effect, but it is recommended to fully charge new batteries before use. Cycling the battery a few times will improve performance.
2. Avoid Deep Discharge: Recharge the battery when it reaches about 10% to avoid deep discharge, which can damage the battery's lifespan.
3. Timely Recharging: Avoid storing the battery under low voltage after use. Please recharge it promptly.
4. Long-Term Storage Requirements: If the battery will not be used for a long time, first disconnect it from the device, then charge each cell to about 3.8V for storage. Check the voltage every 3-6 months, and if it drops below 3V per cell, recharge it in time.
5. Proper Charging Method: First, connect the charger to the battery pack, then plug the charger into the AC power supply. Charge according to the manufacturer's recommended parameters.
6. Waterproof, Moisture-Proof, and Shockproof: Ensure the battery pack is protected against water, moisture, and shocks.
7. Do Not Disassemble: It is strictly forbidden to impact, squeeze, or privately disassemble the battery pack.
8. Transportation Requirements: Do not transport the battery pack with a full charge over long distances.
