Batteries (Electric Machines); Quarterly Battery Maintenance - JLG t350 Service And Maintenance Manual

SECTION 3 - CHASSIS & TURNTABLE

3.22 BATTERIES (ELECTRIC MACHINES)

The electrical system is a 24 volt system, supplied by four,
six volt, 220 amp-hour batteries. Two batteries are located
on the right side of the frame and two are located on the
left side. A gray quick disconnect is used to disconnect
electrical power between the batteries and the machine if
needed.
NOTE: Battery weight is important for stability. Each battery
weighs 59 lbs. (26.8 kg). Do not use batteries that
are not approved by JLG.
IF REPLACING A BATTERY, EACH NEW BATTERY MUST WEIGH
AT LEAST 59 LBS (26.8 KG). FAILURE TO REPLACE THE BATTERY
WITH ONE OF THE CORRECT WEIGHT WILL RESULT IN A
TIPOVER HAZARD WHICH COULD RESULT IN SERIOUS INJURY
OR DEATH.

Quarterly Battery Maintenance

1. Open battery compartment cover to allow access to
battery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELEC-
TROLYTE COVERS PLATES. DO NOT CHARGE BATTERIES UNLESS
ELECTROLYTE COVERS THE PLATES.
NOTE: When adding distilled water to batteries, non-metallic
containers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
When adding water to the battery, fill only to level
indicated or 3/8" above separators.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring
approximately one inch from top of battery. Fill bat-
teries with distilled water only. Replace and secure
all vent caps.

3. Remove battery cables from each battery post one
at a time, negative first. Clean cables with acid neu-
tralizing solution (e.g. baking soda and water or
ammonia) and wire brush. Replace cables and/or
cable clamp bolts as required.
4. Clean battery post with wire brush then re-connect
cable to post. Coat non-contact surfaces with min-
eral grease or petroleum jelly.
5. When all cables and terminal posts have been
cleaned, ensure all cables are properly positioned
and do not get pinched. Close battery compartment
cover.
6. Start hydraulic system and ensure that it functions
properly.
