2. Turn the power switch of the car to the off position. If some cars don't have a power switch, please turn the switch to the stop position between remote control and manual, or the stop position between forward and backward switches. Some cars only have forward and backward switches, please switch to the forward position.
3. Look for charging ports, some are round and some are flat. Unplug the plug, align the charger plug with the battery plug, then plug it tightly and plug the charger into the power supply.
4. The initial charging time is 6- 10 hour. When the remote control car is tested and all functions are good, it can be charged. The new battery is generally about 50%, that is, the battery has electricity, but the electricity is insufficient. So the new car should be recharged before playing. Then don't run out of power every time you use it. If the car is slow or weak, it can be recharged. The car can only be recharged when it is completely stationary. Each charging time is about 8- 10 hour.
5. The evaluation criteria of battery dead are: the speed is obviously slower than before, the energy is insufficient, or it is difficult to start, the light is dim and the sound is light, and it has been used for nearly one and a half hours. When you find these symptoms, you should charge them in time. Because if you don't charge the car right away, there may still be electricity after a long time. Some parents will think that you will continue to play when there is electricity. In this case, excessive discharge can easily shorten the battery life. In the future, the battery will not be fully charged, and some customers complain that my car will be dead after playing for a while. Maybe it's because electricity is used too much.
