1. When you get the new battery, run it down to 5% (not 0%), then power it up to 95%, and repeat this cycle 3-4 times to wake up the new battery.
2. The important point is to carry out a full run-down and power-up cycle every other month to extend the battery life.
3. When using the battery, do not keep it connected to the adapter for a long time, as this may damage the battery.
4. Avoid subjecting the battery to manual impact, disassembly, crushing, or puncturing. Do not dispose of the battery in fire or water.
