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.
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 (i.e. 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). It may require several 8-12 hour cycles for bring severely
discharged batteries back to 100% charged condition.
If again the Delta-Q Charger has the RED FAULT LED (Fig. 4.5.1 No. 6) flashing there is a problem with one or more
of the batteries.
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.
NOTICE: Batteries should be fully charged before performing specific gravity tests to determine battery
condition. Hydrometer tests of batteries not fully charged are misleading and inconclusive.
There are different type hydrometers. Carefully read and follow the instructions supplied with your
hydrometer.
NOTICE: Specific gravity readings are at 80
0
F. Values need adjustment for electrolyte temperature. Reduce
.004 for every 10
0
F below 80
0
F. Increase by that amount for every 10
0
F above.
