In general, the normal life of a car battery is 2-3 years, but if it is used improperly, it is likely to damage or shorten the service life of the battery. Therefore, the owner should use the car battery properly at ordinary times.
Battery Usage Note 1. It is best not to use the electrical equipment in the vehicle for a long time in case of flameout, so as not to damage the battery.
2. Do not use external power supply equipment in the off state. Many car owners will always have car vacuum cleaners, portable air pumps, etc., but they must not use them when they are off. Because these devices have relatively large power, they will consume the electricity stored in the car batteries and affect the normal start-up of vehicles.
3, don't forget to turn off the headlights after parking. The owner of Mr. Wang went to Hangzhou by self-driving tour, forgot to turn off the headlights after parking, and the next day, the vehicle directly collapsed. Rescuers were on the scene and gave him a battery maintenance class.
4, long-term parking needs regular charging. The battery will be consumed when the vehicle is idle, so don't forget to charge your car's battery when you stop.
Battery self-checking method 1. Calculate the effective shelf life of ordinary batteries for 12-24 months, and the useful life of car batteries for 2-3 years. Different brands and models have different battery warranty periods. Near summer, owners must pay attention to the validity period of their own batteries, owners who have passed the shelf life need to pay special attention, even if they can successfully start the vehicle, but also need to be replaced. Storage batteries are consumables and not durable goods. When the shelf life is reached, the internal core raw materials are already “sub-healthy†and there is a possibility of failure at any time. Therefore, we should uphold a good car-keeping habit of actively changing for three years.
2, to see the situation of comprehensive battery use time, pay attention to the use of the vehicle in the daily driving details, such as the smoothness of the ignition, headlight brightness, electrical usage and other issues, in order to determine the use of car batteries.
3. Voltage test For owners who can visually observe the battery and have strong hands-on ability, the experts also give a more objective self-test method, which can be judged at home through the voltage of the multimeter. The voltage is the cause of the charge-generating current. The voltage is divided into open-circuit voltage, charging voltage, and discharge voltage. The 12V battery is shown on the box and the open circuit voltage is generally above 13V. Test results less than 12.4V need timely charging; test results less than 12V suggest replacing the battery.
