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 following 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 char-
ger’s serial number and charge algorithm setting
available when calling.
Checking/Changing the Battery Charge Algorithm
The charger is pre-loaded with programming algorithms
for the specific batteries detailed in Table 5-5, 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/display
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 fol-
lowed 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 dur-
ing 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 timeout 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 terminal 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.
