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

2. In the future, when riding the electric scooter every day, no matter 10-50km, it should be recharged to make the battery in a "full state" for a long time. Moreover, the battery will be charged on the same day, and it will be recharged after being idle for a few days, which will easily lead to the sulfuration of the plate and the decrease of capacity. However, the charging time should not be too long, and the charger should be changed for one hour. When charging, it is better to under charge or over charge the battery, because it will bulge and swell after water shortage. Cause irreparable loss to battery.

3. Do not allow water to enter the battery box to cause battery connection in the case.

4. Once a month, the battery should be fully discharged once a month (riding until the "under voltage" light is on), that is, long-distance riding until the under voltage indicator light flashes and the power is used up, and then charge to restore the battery capacity. It also enables you to know the current capacity level of the battery and whether it needs maintenance protection, and then charge continuously for 12 hours.

5. If possible, switch the monomer in the whole battery. For the battery beyond the warranty period (especially in summer), add 3-4 ml of deionized water to each cell every three or four months.

6. Once it is found that the charger does not turn green or turns green when charging, be sure to check whether there is a problem with the charger or water loss.

7. The discharge port and charging port of the whole set of batteries should be kept clean at any time to prevent copper rust at the contact points, resulting in poor contact, overheating and damage.

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

A set of batteries can be used for more than 5 years with proper charging and normal maintenance. Many users only use 1-2 years to replace, mainly due to improper charging. Therefore, it is very important to master the correct charging method. Remember that the battery is not broken, it is charged.
