Do you know a few of the disadvantages of lead-acid batteries

　　 If you use inferior chargers, faulty chargers, chargers with too high charging voltage parameters or too long charging time, the battery will lose water and the electrolyte will dry up prematurely, which will easily lead to charging deformation and terminate the battery life.

　　 1. Does this new electric car have to charge the battery before it can be used?

　　 Generally not needed. Although there is a certain time interval from the factory to use, the battery has a certain self-discharge capacity, but the self-discharge capacity is not large, but the first mileage is slightly less, so When charging with 20%≤30%, it is necessary to cut off the switch to lock the power supply, and the charging must be done at one time.

　　 Second, if you travel for a long time, what should you do with the battery when the electric car is not in use?

　　 The battery must be stored in sufficient power and must be recharged once a month in the future to avoid the decrease in battery capacity due to the long-term loss of electricity storage, thereby affecting the use of the battery Life, even scrapped batteries.

　　 Third, when the battery is overcharged, what is the hazard to the battery?

　　 If you use inferior chargers, faulty chargers, chargers with too high charging voltage parameters or charging time for too long, it will cause the battery to lose water and the electrolyte to dry up prematurely. Lead to deformation of charging, and early termination of battery life.

　　 4. The mileage of electric cars is very short, is it all because of the battery?

　　 Not necessarily. When the battery life and capacity are reduced, the battery mileage will become shorter, but the following problems that are not part of the battery will also cause the battery mileage to become shorter
