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 6 to 10 hours.
If vehicle is used only occasionally, a refresher charge should be given prior to using.
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.
3.7 CHARGER INFORMATION
The built-in battery charger is custom made for Columbia vehicle CR-10 Models. Its operation is totally
automatic. When connected to a 110 - 120 Volt AC power source, the charger's electronic timer will turn
the charger on. It determines and provides the energy necessary to return batteries to a fully charged
state, automatically shutting off when the batteries are fully charged. This occurs when each cell reaches
approximately 2.5 volts.
3.8 CHARGER OPERATING INSTRUCTIONS
Plug 120 volt AC supply cord into charger receptacle on charger panel. After a short time delay of
approximately 5 to 6 seconds, a RED light comes on indicating battery charging.
When the solid state circuitry senses that the batteries are fully charged, the RED light turns off and the
GREEN light turns on indicating that charging is complete.
The GREEN light will remain on until the AC cord is disconnected. At that point the light will turn off and
the charger will reset itself for the next charging cycle.
3.9 LOW BATTERY RESET SWITCH:
This is used if the batteries are heavily over discharged. When the AC cord is connected, the RED light
will turn on but will shortly turn off. To reactivate the charger, push the reset button for 10 seconds. This
will restart the charger. Release the button and the charger will continue to charge.
