1. Check whether the fixing bolt of the battery on the bracket is tightened or not. Installation is not reliable, and the housing will be damaged due to driving vibration. In addition, do not put metal on the battery to prevent short circuit.

2. Always check whether the pole and wiring head are connected reliably. Vaseline and other protective agents can be applied to prevent oxidation of the terminal.

3. Can not use direct ignition (short circuit test) method to check the battery’s power, which will cause damage to the battery.

4. Regular addition of distilled water should be paid attention to in ordinary lead-acid batteries. Dry-charged batteries should be properly charged before they are used. As for water-added maintenance-free batteries, it is not impossible to maintain them properly. Supplementation of distilled water when necessary will help prolong their service life.

5. The air holes on the battery cover should be unobstructed. When the battery is charged, a large number of bubbles will be generated. If the air vent is blocked, the gas can not escape. When the pressure increases to a certain extent, the battery shell will burst.

6. There are often yellow-white pastes around the battery pole and cover, which are caused by sulfuric acid corrosion of the root pole, wire clip, fixture, etc. The resistance of these substances is very high, so they should be removed in time.
