Excessive Battery Watering Requirements or Strong
Sulphur (Rotten Egg) Smell
These symptoms indicate over-charging or high battery
temperature. These symptoms are unlikely to be caused
by too high a charge current since the maximum charge
current of the charger will be small compared to even a
moderately sized battery pack. The most likely cause for
this problem is incorrect charge algorithm setting and/
or high ambient temperatures.
1. Confirm that the battery pack is not too small -
usually > 50Ah.
2. Confirm that the nominal battery voltage matches
the charger output voltage.
3. Confirm the correct battery charge algorithm. If
the battery pack is new, the algorithm will need to
be changed if the pack is not the same as the old
one. for instructions on how to determine and
change the battery charge algorithm see the fol
-
lowing sub-section.
4. If the output voltage of the charger seems exces
-
sive, return the charger for service. Contact JLG to
get the expected battery voltage settings for the
charger in question. Be sure to have the charger’s
serial number and charge algorithm setting avail
-
able when calling.
Checking/Changing the Battery Charge Algorithm
The charger is pre-loaded with programming algo
-
rithms for the specific batteries detailed in Table 3-5,
Battery Algorithms. Contact JLG if your specific battery
model is not listed.
Each time AC power is applied with the battery pack not
connected, the charger enters an algorithm select/dis
-
play mode for approximately 11 seconds. During this
time, the current Algorithm # is indicated on the Yellow
Charging LED. A single digit Algorithm # is indicated by
the number of blinks separated by a pause. A two digit
Algorithm # is indicated by the number of blinks for the
first digit followed by a short pause, then the number of
blinks for the second digit followed by a longer pause.
To check/change the charging algorithm:
1. Disconnect the charger positive connector from
the battery pack. Apply AC power and after the
LED test, the Algorithm # will display for 11 sec
-
onds.
2. To change the algorithm, touch the connector to
the battery’s positive terminal for 3 seconds during
the 11 second display period and then remove.
The Algorithm # will advance after 3 seconds.
Repeat this procedure until the desired Algorithm
# is displayed. A 30 second time-out is extended
for every increment. Incrementing beyond the last
Algorithm will recycle back to the first Algorithm.
When the desired Algorithm is displayed, touch
the charger connector to the battery positive ter
-
minal until the output relay makes a clicking noise
(approx. 10 seconds). The algorithm is now in the
permanent memory.
3. Remove the AC power from the charger and
reconnect the charger’s positive connector to the
battery. It is recommended to check a newly
changed algorithm by repeating the above steps 1
and 3.
