Ordinary lead-acid batteries, pay special attention to the usual cleaning work. Pay attention to check whether the pole and the chuck are tightly connected, if there is any corrosion and burning, and if the vent hole is blocked or not, and if the electrolyte is reduced, if it is found, it should be disposed of in time. When starting the car, the start time should not exceed 3 to 5 seconds, and the restart interval should be no less than 10 seconds. If the car is not used for a long time, the car should be fully charged. At the same time, the car will be launched once every other month and keep running at a medium speed for about 20 minutes. Otherwise, the placement time is too long and it will be difficult to start. General maintenance-free batteries should also be checked frequently, and problems should be replaced in time.
Maintenance-free batteries are now available in most cars. These batteries do not require the addition of distilled water during use. The terminals do not corrode, have less self-discharge and have a long life. However, if it is not checked in time, the battery is not clear to the owner of the scrapping period, which will also affect the normal operation of the car.
