BATTERIES APPROVED BY JLG HAVE BEEN TESTED FOR
COMPATIBILITY WITH THE ALGORITHM PROGRAMMING
OF THE DELTA Q BATTERY CHARGER TO OPTIMIZE BAT
-
TERY LIFE AND MACHINE CYCLE TIMES. THE USE OF NON
APPROVED BATTERIES 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.
Replacement battery (s) must be of equivalent voltage and
amperage output as the OEM battery (s) in order for the
machine to operate to as manufactured specifications. Battery
replacement part weight must also be equivalent to OEM per
battery, in order to maintain machine stability as manufac
-
tured.
(See Section 1 of this manual for battery specifications)
.
DO NOT REPLACE ITEMS CRITICAL TO STABILITY, SUCH AS
BATTERIES, WITH ITEMS OF DIFFERENT WEIGHT OR SPECI
-
FICATION. DO NOT MODIFY UNIT IN ANY WAY TO AFFECT
STABILITY.
Battery Condition Testing
Note:
Batteries in storage should be kept at 12.5V or higher.
Before testing for battery condition, the open circuit voltage
should be taken from each battery. If the voltage of the batter
-
ies differs by 0.3 volts or more, the lower voltage battery
should be replaced.
Battery Testing Can Be Performed In Two Ways:
1.
The batteries can be tested using a battery tester capa
-
ble of testing 12V 100Ah AGM VRLA
(Valve Regulated
Lead Acid)
batteries, using the instructions of the battery
tester manufacturer.
2.
If an appropriate battery tester is unavailable, the batter
-
ies can be tested by fully charging them with the char
-
ger that is installed on the machine. Then check the
battery voltage of each battery - 4 hours - after charging
is complete. Batteries less than 12.72 volts should be
replaced.
Note:
If a faulty charger is suspected, the batteries can be charged
using a charger that supplies 2.45 volts/cell. Charging
should be terminated when the charge current drops below
1 amp.
Battery Disconnect (Option)
If equipped, the optional battery disconnect loop is located on
the left side of the mast assembly, just above the rear cover
assembly. Battery electrical power to the machine is discon
-
nected when the upper half of the connector is separated
from the fixed lower half connector. Use the wire handle pro
-
vided on the front of the upper half connector to disconnect it
from the lower half. A lanyard keeps the upper half attached to
the machine when disconnected.
