Slow Battery Charging
NOTE: Follow the instructions that come with
your battery charger. It is not necessary to
remove the battery from the compartment.
1. Make sure the electrolyte level in each cell is between
the “MIN” and “MAX” marks. If the fluid level is below
the “MIN” mark, correct the condition.
2. Disconnect the battery cables.
3. Connect charger cables.
4. Start charging the battery at a rate not over 6
amperes. Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
5. After charging, turn OFF charger and disconnect
charger cables.
Jump Starting Batteries
If your battery is discharged (dead), you may be able to
start it by using energy from a good battery in another
vehicle. This is termed “jump starting.” Because of the var
-
ious battery installations in optional electrical systems,
Peterbilt does not recommend that you attempt to jump
start your vehicle. If you have a battery problem, contact a
Peterbilt Dealer or a reputable towing service. But if you
are unable to do this, and must jump-start your vehicle,
then ensure that you follow the precautions and instruc
-
tions below.
WARNING! Batteries contain acid that can
burn and gasses that can explode. Ignoring
safety procedures can cause you or others to
be badly hurt.
• Never jump start a battery near fire, flames,
or electrical sparks. Batteries generate
explosive gases. Keep sparks, flame, and
lighted cigarettes away from batteries.
• Do not allow battery fluid to contact eyes,
skin, fabrics, or painted surfaces. Always
wear eye protection. Battery acid that may
spill during charging should be washed off
with a solution of warm water and baking
soda to neutralize the acid. If you acciden
-
tally get acid in your eyes or on your skin,
immediately rinse with cold water for sev
-
eral minutes and call a doctor.
• Be careful that metal tools or any metal in
contact with the positive terminal do not
contact the positive battery terminal and
