12 Points of Attention for Daily Maintenance of Lead-Acid Batteries：

1. The battery must be kept clean regularly.

2. Avoid letting any foreign impurities fall into the battery.

3.All tools and materials used must be stored in a clean and covered place.

4. It is necessary to regularly wipe off dirt and dust from the entire external surface of the battery.

5. The contact devices between individual cells and the connections with wires must be secure and reliable.

6. If the battery has a sealed cover and vent plugs, the vent holes must be regularly checked and cleaned.

7. During the discharge process, regularly check the terminal voltage and electrolyte density of each individual cell. Pay close attention to the degree of discharge of the battery, 

and never allow the electrolyte density and terminal voltage to fall below the level permitted by the discharge specifications specified for the battery.

8. The electrolyte temperature must not exceed the specified value in the manual, generally 55°C.

9. The charging current must not exceed the manufacturer's specifications.

10. Perform regular supplementary charging according to the manual.

11. If the battery is stored for an extended period, to prevent excessive self-discharge and severe sulfate formation, perform supplementary charging once a month.

12. Discharge current exceeding the maximum limit specified by the manufacturer is not allowed for the battery.
