What should I do if I find that the battery life of MN MODEL MN128 RC CAR is insufficient during use?

Answer: If the battery life is insufficient, first check whether the battery is fully charged and make sure that an adapted charger is used. Avoid using a charging head with an output current exceeding 2A. In addition, do not leave the battery empty for too long to avoid deteriorating battery performance. If the battery is seriously aged, it is recommended to replace it with a new battery.
