1. Strengthen maintenance, keep the cover of the battery clean.

2. Ensure high purity of electrolyte. When preparing electrolyte and adding distilled water, strictly prevent impurities from entering.

3. The battery should be charged frequently in the storage process, so that the electrolyte density remains even, and the liquid level will not fall.

4. When washing the outside of the battery, prevent sewage from entering the inside of the battery from the refueling cap or air hole.

5. Clapboard and plate should be repaired or replaced in time when damaged.

6. When replacing electrolyte, be sure to clear the residual liquid in the battery.
