to the upper limit.
Caution
Don't fill in too much distilled water, or the
electrolyte may overflow and corrode the

Only distilled water is allowed. If any
impure water is filled in, it will shorten the
battery life.
Warning
The electrolyte contained sulfuric acid.
Please avoid touching the eyes, skin, or
clothes. If any contact by accident, please
flush with plenty of water.
If there is some rust on battery posts, clean it
with steel brush.
Install the battery in the reverse procedures of

Caution
If the rust on the posts is very serious,
spray some hot water on them. Then,
more easily you can remove the rust by
steel brush.
Apply some grease on the posts after
cleaning rust to prevent from happening
