The maintenance methods of electric bikes batteries are as follows:
1. If the battery of the electric vehicle loses water: you can pry off the protective cover of the battery of the electric vehicle, and use a dropper to inject distilled water into the battery from the exhaust hole. You should pay attention to the principle of "less but not more".
2. If the positive electrode of the electric vehicle battery is softened: after the electric vehicle battery is discharged to 10.5V, use the bulb to deeply discharge it for 1-5 hours, and then activate the repair with an activator.
3. If the electric vehicle battery is short-circuited: the battery can be perforated, and the short-circuited lead powder can be removed. If the battery of the electric vehicle is short-circuited, the positive and negative poles can be quickly short-circuited, and the short-circuited part can be burned.
4. If the electric vehicle battery has an open circuit: 100A detects that the battery voltage is 0V, which means that there is a short circuit. A single measurement method can be used to measure the open circuit with a multimeter, and then welding can solve the problem.
5. If the electric vehicle battery swells: the corresponding battery can be repaired. If it is an expansion battery that cannot be repaired, it is recommended to replace it with a new battery.
In addition, the general service life of lithium batteries for electric vehicles is about 2-3 years. After this point in time, there is no maintenance value. Also pay attention to the maintenance of the battery. When the electric vehicle starts, carries people, or goes uphill, it is best to use pedal assistance to avoid instantaneous high current discharge as much as possible. The battery should be deeply discharged every 1-3 months to prolong the battery life.
