3.3 BATTERY MAINTENANCE AND
CHARGING
IF REPLACING A BATTERY, EACH NEW BATTERY MUST WEIGH
AT LEAST 52 KG (115 LB). 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.
JLG MACHINES EQUIPPED WITH DELTA Q BATTERY CHARGERS
ARE DESIGNED FOR THE BEST PERFORMANCE WITH OEM FAC-
TORY APPROVED BATTERIES.
APPROVED JLG REPLACEMENT BATTERIES ARE AVAILABLE
THROUGH JLG' S AFTERMARKET PARTS DISTRIBUTION CEN-
TERS OR JLG' S AFTERMARKET PROGRAMS. FOR ASSISTANCE
WITH PROPER BATTERY REPLACEMENT, PLEASE CONTACT
YOUR LOCAL JLG SUPPORT OFFICE.
BATTERIES APPROVED BY JLG HAVE BEEN TESTED FOR COM-
PATIBILITY WITH THE ALGORITHM PROGRAMMING OF THE
DELTA Q BATTERY CHARGER TO OPTIMIZE BATTERY LIFE AND
MACHINE CYCLE TIMES. THE USE OF NON APPROVED BATTER-
IES IN YOUR JLG EQUIPMENT MAY RESULT IN PERFORMANCE
ISSUES OR BATTERY CHARGER FAULT CODES. JLG ASSUMES
NO RESPONSIBILITY FOR SERVICE OR PERFORMANCE ISSUES
ARISING FROM THE USE OF NON APPROVED BATTERIES.
SEE TABLE 3-4, BATTERY ALGORITHMS ON PAGE 3-11.
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to
battery terminals and (vent caps-wet batteries only).
WHEN ADDING WATER TO (WET) BATTERIES, ADD WATER
UNTIL ELECTROLYTE COVERS PLATES. DO NOT CHARGE BAT-
TERIES UNLESS ELECTROLYTE COVERS THE PLATES.
NOTE: When adding distilled water to (wet) 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 (wet batteries only) and
inspect electrolyte level of each cell. Electrolyte level
should be to the ring approximately one inch from
top of battery. Fill batteries 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.
Optional On-Board Generator
EXHAUST GAS HAZARD. RUN THE GENERATOR IN A WELL VEN-
TILATED AREA ONLY.
WHEN THE GENERATOR ENABLE CONTROL LOCATED IN THE
PLATFORM CONTROL BOX IS IN THE ON POSITION AND THE
GROUND EMERGENCY STOP SWITCH IN ON (PULLED OUT), THE
GENERATOR WILL START AUTOMATICALLY WHEN THE BAT-
TERIES REACH A LOW-CHARGE STATE AUTOMATICALLY
CHARGING THE BATTERIES.
NOTE: The generator engine will automatically shut down
under the following conditions:
Fully Charged Batteries
High Engine Oil Temperature
Low Engine Oil Pressure
Engine Overspeed
Generator Overvoltage
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR
ALLOW SPARKS OR A FLAME NEAR BATTERY DURING SERVIC-
ING. ALWAYS WEAR EYE AND HAND PROTECTION WHEN SER-
VICING BATTERIES.
Battery Charging (On Board Charger) (MAC)
1. For maximum battery life:
a. Avoid completely discharging the batteries.
b. Fully charge the batteries each day the machine
is used.
c. Charge the batteries at available times between
charging.
d. Be sure the battery fluid covers the battery
plates before charging, but to avoid overflow, do
not top off the fluid level until charging.
