The editor has sorted out some suggestions on maintaining the battery. If necessary, you can store it for a rainy day.

1. After purchasing a small excavator, first read the manual carefully to understand its structure.

2. Under normal circumstances, the generator runs automatically after starting, which can fully charge the battery, but in winter, the battery pack should be kept fully charged to avoid freezing.

3. The battery is easy to be oxidized by acid after being used for a long time. If the situation is not serious, it can be restored to normal after 1-2 charges with a small current.

4. Always clean the surface of the battery. If dust or electrolyte is found, it is best to wipe it with a rag soaked in ammonium chloride alcohol or 10% ammonium sulfate solution.

The working efficiency of the small excavator can directly affect the progress of the overall construction, and the battery is equivalent to its core equipment, so doing a good job of maintaining the battery will help extend its service life and improve work efficiency.
