1. If the battery is not used for a long time, it will slowly discharge itself until it is disused. Therefore, you should start the car once every certain time to charge the battery. Another way is to unplug the two electrodes on the battery, it should be noted that to unplug the positive and negative electrode wires from the electrode post, you should unplug the negative wire first, or remove the connection between the negative pole and the chassis of the car. Then unplug the other end with the positive pole mark (+), the battery has a specific service life, to a specific period to replace. When replacing, also follow the above order, but when connecting the electrode wire, the order is the opposite, first connect the positive terminal, and then connect the negative terminal.

2. When the ammeter pointer shows that the storage capacity is insufficient, it should be charged in time. The storage capacity of the battery can be reflected in the instrument panel. Sometimes, when you find that the power is not enough on the road and the engine stalls, as a temporary measure, you can ask for help from other vehicles and use the battery on their vehicles to start the vehicle by connecting the negative terminal of two batteries to the negative terminal and the positive terminal to the positive terminal.

3. The density of electrolyte should be adjusted according to the standard in different regions and seasons.

4. When losing electrolyte, distilled water or special replenishment solution should be added. Never use pure water instead of drinking water. Because pure water contains many kinds of trace elements, which will have a bad effect on the battery.

5. When starting the car, uninterrupted use of the starter will cause damage to the battery due to excessive discharge. The correct way to use is to start the car for no more than 5 seconds each time, and to start again for an interval of not less than 15 seconds. In the case that the car still does not start for several times, the cause should be found from other aspects such as circuit, ignition coil or oil circuit.

6. Check whether the small hole on the battery cover is ventilated or not when driving everyday. If the small hole of the battery cover is blocked, the hydrogen and oxygen produced will not be discharged, and the electrolyte expansion will break the battery shell and affect the battery life.

7. Check the positive and negative levels of the battery for signs of oxidation. You can pour hot water on the battery wire connection from time to time.
