1. After buying a car (or replacing the battery), the battery should have about 80% of the power. It should be charged when you get home. The time should be 4 hours after the charger changes the light. It takes three times.

2. In the future, we should insist on charging every day (36V riding for 10km and 48V riding for 15km), but the charging time should not be too long. It is appropriate to charge the charger for an hour after the light changes. When charging, it is better to under charge rather than over charge, otherwise the battery will be charged, because it will swell and swell after water shortage. Cause irreparable loss to the battery.

3. Do not let water enter the battery box, so as to cause the battery in the shell to be electrified.

4. Fully discharge once a month (ride until the "undervoltage" light is on), and then charge continuously for 12 hours.

5. Check if there is a problem with the charger when it turns green or if there is a loss of water.

6. The discharge port and charging port of the whole battery shall be kept clean at any time to prevent copper rust at the contact point, resulting in poor contact and overheating damage.

7. If there are pedals, try to start with your feet. Don't load too much and accelerate gently. Don't start the car with electricity.

A group of batteries can be used for more than 5 years under the condition of correct charging and normal maintenance. Many users only need 1-2 years to replace them, which is mainly caused by improper charging. Therefore, it is very important to master the correct charging method. Remember that the battery is not broken, but charged.
