Inspection

Notice

z

When charging the battery, do not leave the inflammable

objects around it.

z

When checking the electrolyte of battery, put on

an eye protector and gloves.

1. Inspect the surface of the battery and replace if any defects

were found on it.

2. Check if the specific gravity of the electrolyte is within the

specified value.

Notice

z

Replace the battery if the maximum tolerance of the

electrolyte between cells is out of the specified value.

z

Measure the specific gravity in the approx. 20°C

of ambient temperature.

3. Replenish the electrolyte if necessary.
