Columbia Delta-Q Operation

Delta-Q Automatic Charger Operation

Battery Charging Summary:

All current production Columbia 24/36/48 volt electric vehicles are built with a new solid state on-board, fully
automatic Delta Q Battery Charger as standard equipment. It is important to be aware of the differences and
improvements over prior chargers. This bulletin explains in more detail the Delta Q Charger Operating
Instructions that accompany every vehicle.
Always schedule enough charging time so the Delta Q Charger attains the 100% level, illuminates the 100%
Green LED, and automatically stops the charging cycle. Charging time is affected by age and battery condition,
state of discharge, electrolyte temperature, AC line voltage, and other variables. Correct charging methods
extend battery life and vehicle range between charges. Before the first new vehicle use, completely charge new
batteries. Charging time will vary based on conditions noted above but will probably be 12 hours. New
batteries need up to four hours more charging than "mature" batteries.
Limit new batteries use between charges for the first 15-20 cycles. New batteries have less capacity than
seasoned batteries. New batteries should not be discharged more than 20-30% before recharging. This practice
prevents premature battery failure.
The AC power Yellow LED should remain illuminated while the charger is plugged into an AC source. If
charger does not power up, after following the instructions described in step 1, then contact your Columbia
Dealer for assistance.
Do Not Disassemble the Charger. There are No Serviceable Components.

Charger Operating Instructions:

1. Connect power cord at charger receptacle to proper grounded wall outlet.
Note: The AC cord to each charger is to be connected to a source capable of supplying 15 amperes minimum
per charger (20 amperes recommended). The charger is equipped with an equipment-grounding AC electric
cord, and a grounding type plug. Connect the cord to an appropriately installed receptacle grounded in
accordance with the National Electric Code ANSI/NFPA 70, and all local codes and ordinances.
The Yellow AC power LED [(1) in figure below] should remain illuminated while the charger is plugged into
an AC source. If the Yellow LED [(1)] is not lit, before replacing charger inspect and confirm the two AC
connections supplying the charger on the vehicle are intact. First is the extension cord receptacle, typically
found behind the left leg of the driver on the vehicle's body. Second is the three pronged quick connection on
the short 6" AC cord extending from the LED panel. Also confirm your AC source fuse or breaker operation,
then contact your Columbia Dealer for assistance.
