Battery Maintenance

BATTERY CONNECTORS

A special heavy-duty connector is used to connect the
battery to the electrical system of the lift truck. See
Figure 22 and Figure 23. When a connector has a
handle and is within the operator’s reach, the connec-
tor is also a safety device that can be used to quickly
disconnect the battery in an emergency. Most con-
nectors have a handle to connect the two halves of the
connector. The connector can be quickly disconnected
by pulling the handle upward. This action separates
the two halves of the connector. The connector and
its attached handle must be kept in good repair so
that it will function correctly. The battery connec-
tor must be disconnected when maintenance is done
on the lift truck that does not require electric power.
The SBE, SBX, and FEM or DIN 12- volt battery con-
nectors are shown in Figure 23.

BATTERY CARE

1.

Keep batteries clean. Remove any spilled elec-
trolyte.

2.

DO NOT overcharge the battery. This action will
damage the battery.

3.

DO NOT discharge the battery to less than the
recommendation. A deep discharge will shorten
the battery life.

4.

Charge batteries in an area with good ventilation
to remove explosive gases and acid fumes.

5.

Keep the electrolyte at the correct level. Check
the electrolyte level before and after charging the
battery. Use distilled water. Do not add acid.

6.

Prevent batteries from freezing.

7.

Keep batteries charged. A discharged battery in
storage will shorten the battery life.

8.

Use a battery charger that is correct for the bat-
tery. A battery charger that is set for an am-
pere-hour rate that is too high will cause a high
internal heat and damage the battery. A low am-
pere-hour rate setting on a battery charger can
require a longer charging time but will not dam-
age the battery.

9.

When batteries are moved, make sure a short
circuit does not occur. See the Safety Procedures
in Battery Maintenance of this section.
