⌈Lead Acid Batteries Cleaning⌋
1. Keep the battery appearance and working environment clean and dry.
2. The cleanliness of storage battery should avoid static electricity.
3. Clean batteries with wet cloth, prohibit the use of gasoline, alcohol and other organic solvents, and do not use cloth batteries containing these substances.


⌈Lead Acid Batteries Inspection and Maintenance⌋
1. The principle of “detecting hidden dangers and ensuring safety” should be followed in battery testing.
2. The daily maintenance items and performance analysis of batteries should be carried out in strict accordance with the operation plan.
3. Strictly follow the maintenance rules and battery-related requirements for battery parameter setting and related operation.
4. Do a good job of safety protection, wear good insulating gloves, and insulate metal tools.
5. Use tools and instruments that meet the testing requirements.
