Using Booster Batteries-24-Volt System; Replacing Batteries - Worldwide Construction And Forestry Division 380GLC Operator's Manual

Using Booster Batteries—24-Volt System
Before boost starting, machine must be properly shut
down to prevent unexpected machine movement when
engine starts.
CAUTION: An explosive gas is produced while
batteries are in use or being charged. Keep flames
or sparks away from the battery area. Make sure
the batteries are charged in a well-ventilated area.
IMPORTANT: The machine electrical system is a
24-volt negative (-) ground. Connect two 12-volt
booster batteries together as shown for 24 volts.
1. Connect one end of the positive (+) cable to the
positive (+) terminal of the machine batteries (A) and
the other end to the positive (+) terminal of the booster
batteries (B).
2. Connect one end of the negative (-) cable to the
negative (-) terminal of the booster batteries. Connect
the other end of the negative (-) cable to the machine
frame as far away from the machine batteries as
possible.
3. Start engine.

Replacing Batteries

CAUTION: Avoid personal injury from battery acid.
Sulfuric acid in battery electrolyte is poisonous. It
is strong enough to burn skin, eat holes in clothing
and cause blindness if splashed into eyes.
NOTE: Reserve capacity is the time in minutes it
takes a fully charged battery at 26.6°C (80°F)
to drop below 10 volts.
Your machine has two 12-volt batteries (1) with negative
(-) ground connected in series to provide 24-volts.
Use only batteries which meet the following specifications.

If one battery in a 24-volt system has failed but the other is
still good, replace the failed battery with one of the same

4. Immediately after starting engine, disconnect the end
of the negative (-) cable from the machine frame. Then
disconnect the other end of the negative (-) cable from
the negative (-) terminal of the booster batteries.
5. Disconnect positive (+) cable from booster batteries
and machine batteries.

type. For example, replace a failed maintenance-free
battery with a new maintenance-free battery. Different
types of batteries may have different rates of charge. This
difference could overload one of the batteries and cause it
to fail.
