Carrier and holding-down clamp

Before the battery is installed, the carrier and holding-down device should be
cleaned. And they should be prevented from corrosion. The carrier should maintain a
good status. Ensure that no other materials are on the carrier before the battery is
installed. In order to prevent the battery from swinging in the carrier, the packing bolts
should be reasonably tightened.

Sulfation

If the battery discharges for a long time, the lead sulfate will gradually become a kind
of hard crystalline material, which doesn't tend to return to active material during the
subsequent recharging. "Sulfation" just means such result and reaction process. This
kind of battery can be recovered by means of slow charging. It can be recovered to the
work level, however, its capacity is lower than before.
Solidification of electrolyte
The solidifying point of electrolyte is related to its specific density. The solidification
may damage the battery, so it should be prevented from solidification by means of
keeping full of charge. If the battery is frozen accidentally, it can't be charged before
it warms up.

Maintenance of battery

1 Battery is a reliable component, but it needs regular maintenance. Keep the carrier
of battery clean, prevent the terminal post from corrosion, and make the electrolyte
level maximal. In addition, the liquid level of each unit should be basically equal.
2 Keep the cable plugging device of battery clean.
The cable plugging device, especially the positive terminal, is sure to become rusty.
The rust on the fitting surface of conductor will hinder the circulation of electric
current. It is usually because of the rust on the cable plugging device of battery that
the engine can't be started, while the electromotor is activated. Regularly cleaning it
and lubricating the plugging device may prevent them from corrosion.
