(Usually, if the port size and voltage of your product battery are the same as our battery, it can be universal) 2. When charging the battery for the first time, do I need to use up all the power? Not necessary. The current battery technology is mature, and battery life will not be affected. 3. Can the battery be charged overnight? Yes, the battery has an overcharge protection system, so there will be no safety issues. 4. What is the battery life? 300 full charge-discharge cycles will lose about 20% of the maximum power (about 2 years of use). The battery is consumable, if it affects your product experience, it is recommended to replace it. NOTE: The scientific storage method can avoid permanent damage to the battery. 5.
