New batteries
need up to four hours more charging than “mature” batteries. Before the first use,
completely charge new batteries. Charging time will vary based on conditions noted above but will
probably be 12 hours.
Limit new batteries use between charges for the first 25
– 50 cycles. New batteries have less capacity
than seasoned batteries. New batteries should not be discharged more the 20
– 30% before recharging.
This will prevent premature battery failure.
Battery efficiency is affected by temperature. If the temperature of the outside air and/or batteries is
below 60º F, battery capacity is reduced. Batteries will require more frequent and longer charge periods in
early spring, fall and winter.
As batteries age, they finish charge at progressively higher charge rates and tend to use more distilled
water. At this point in battery age, charger will automatically begin reducing charge time.
Batteries found defective must be replaced. All batteries in a vehicle should be matched according to age,
capacity and brand.
4.5 DELTA-Q BATTERY CHARGING
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 (Figure 4.5A) as standard equipment. This section explains in
more detail the Delta-Q Charger Operations. The Delta Q charge status can be found in two locations. On
the Delta Q face and on a remote multicolored LED (Figure 4-5B). This LED and descriptive label will
located near the Charger Receptacle.
NOTICE:
Do not cover the charger cabinet or cooling fins with clothing, blankets, or other
material. Fins provide ventilation and prevent overheating.
Do not disassemble the charger. There are no serviceable components.
4.5.1 CHARGER OPERATING INSTRUCTIONS
Connect the supplied power cord to the vehicle charger receptacle and to a properly grounded wall outlet.
Charger start and charge time is automatic. The Yellow AC power LED (Fig. 4.5A No. 1) should remain
illuminated while the Charger is plugged into an AC source. The remote LED will be flashing short green.
If these LED
’s are not lit, before replacing Charger, recheck the AC connection and the AC source fuse or
breaker. If this fails to correct the problem, contact your Columbia Dealer for assistance.
