Checking/Changing the Battery Charger
Algorithm
The charger is pre-loaded with programming algorithms
for the specific batteries detailed in Table 3-4, Battery
Algorithms.
NOTE: 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 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 seconds.
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 dis-
played. 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 sec-
onds). The algorithm is now in the permanent mem-
ory.
3. Remove the AC power from the charger and recon-
nect the charger’s positive connector to the battery.
It is recommended to check a newly changed algo-
rithm by repeating the above steps 1 and 3.
