1.The battery shall be checked if it has been used for more than two years

The service life of ordinary automotive batteries is 2-3 years, and the original batteries of new vehicles can be used for more than 3 years. Therefore, if your battery has been used for almost two years, it should be noted that its service life may have expired. At this time, more inspections should be carried out and tests should be carried out in advance. Problems found should be solved or replaced as soon as possible, so as to avoid the loss of the battery caused by sudden "squatting" during use.

2. What should be paid attention to after replacing the battery?

The new battery may be under charged, including the original battery on the new vehicle, which may not be 100% charged. Therefore, after a new battery is replaced or a new car is bought, the engine needs to be operated for a longer time to ensure that the battery can be fully charged.

3. Is it harmful to the battery if the vehicle is not opened for a long time?

Since the battery will self discharge, if the vehicle is not used for a long time, the battery may run out of power, and eventually the vehicle cannot be started or the battery may be damaged.

If the vehicle is not used for a long time, it is better to restart it every 15 days as much as possible, and let the engine run for about 20 minutes each time to fully charge the battery.
