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.
4.6 EXCESSIVELY DISCHARGED BATTERIES
NOTICE
: Columbia Dealer will have the equipment and experience to perform the following
battery inspections.
4.6.1 DELTA-Q WILL NOT CHARGE
The Delta Q will not charge dead batteries. First establish that none of the batteries have an internal fault
or bad cell. If a battery has remained too long in a discharged state (ie. 2-4 volts each), it may be
internally damaged and not capable of accepting a charge and must be replaced.
If the electrolyte Specific Gravity is low (less than 1.1098 SG) or individual battery voltage is les than 5.25
volts for three cells (10.5 volts for six cells), recharge each battery with an ordinary automotive style trickle
charger at a rate of 3 to 6 amps.
It is not necessary to disconnect the battery cables, as the alligator style clips can be connected to each
positive and negative battery post. Follow specific Charger instructions.
To prevent a spark from igniting the gas emitted from the batteries, always disconnect the
Charger AC power cord first when moving the positive/negative alligator clips.
Be sure to charge all of the batteries in the set. Each battery may require two to three hours of charging to
bring it back to serviceable condition. After all batteries have been individually charged, remove the
automotive Charger and restart charging with the Delta-Q Charger (Section 4.5.1). If again the Delta-Q
Charger has the RED FAULT LED (Fig. 4.5 No. 6) flashing there is a problem with one or more of the
batteries.
If repeated cycles (5-7) do not result in a 100% green charge, the batteries are beyond useful life and will
need replacement.
4.7 SPECIFIC GRAVITY TEST
It is possible to determine a battery's ability to perform by measuring the specific gravity (sp. gr.) of each
cell with a hydrometer. This is the best method to determine a defective battery.
The hydrometer readings indicate two things:
State of Charge - The amount of electrical power stored in the battery.
Condition - The ability of battery to store and deliver power.
