CHECK / CHANGE CHARGING ALGORITHM
The charger has been programmed for use with the Columbia ParCar supplied batteries and
contains algorithms for use with different batteries. Table A details these battery models.

NOTICE: For maximum battery life the correct algorithm must be used.
If your battery model is not listed in Table A, contact Columbia ParCar for further

Each time AC power is applied with the battery pack NOT connected, the charger enters an
algorithm select/display mode for approximately 11 seconds. This will be displayed on the
remote LED.
During this time, the current algorithm # is indicated on the LED light. 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:
Disconnect the charger positive connector from battery pack. Apply AC power and after the LED
test, the algorithm # will be displayed for 11 seconds.
To change the algorithm, touch the positive connector during the 11 second display period to
the battery pack’s positive terminal for 3 seconds and then remove. The algorithm # will
advance after 3 seconds. Repeat until the desired algorithm # is displayed. A 30 second timeout
is extended for every increment. Incrementing beyond the last algorithm moves back to the first
algorithm. After the desired algorithm # is displayed touch the charger connector to the battery
positive until the output relay is heard to click (~ 10 seconds). The algorithm is now in
permanent memory.
Remove AC power from the charger and reconnect the charger positive connector to the battery
pack. It is highly recommended to check a newly changed algorithm by repeating the above
steps.
