What should I pay attention to when charging electric tractors?

1. During charging

(1) The specific gravity of the battery electrolyte remains basically stable for more than 2 to 3 hours.

(2) The electrolyte surface in the battery produces strong bubbles, and the electrolyte turns from milky white to clear.

The above conditions indicate that the battery power is sufficient.

1.1 After sufficient

(1) Turn off the charging power supply and charger.

(2) Unplug the charger plug from the battery plug.

(3) Insert the battery power socket into the battery body plug.

2. Battery maintenance

After the battery tractor is charged, the battery should be maintained

2.1 Once a week

(1) Open the covers of all battery filling holes.

(2) Check the acid level in the battery, and pay attention to which batteries consume more acid than normal.

(3) Inject distilled water, the liquid level is 10-15mm higher than the plate.

(4) Close all battery covers again.

(5) Rinse and dry the battery.

2.2 once a month

(1) After the battery electric tractor is charged, measure the temperature of the central battery immediately, and it shall not exceed 50. c.

(2) Use a hydrometer to measure the specific gravity of the electrolyte, keep the hydrometer absolutely vertical, and draw out enough electrolyte so that the float can float freely
