board terminals. If the wiring is good, the battery should to be
replaced.
If the back-up battery needs to be replaced because it has either
failed, or will not keep a charge, a new back-up battery can be
ordered through your local leak detector supplier or directly from
Cool Air Incorporated. Prior to removing the old battery, disconnect
the leak detector power supply, remove the black and red wires from
the battery terminals, cut the wire cable strap (used primarily for
shipping), and remove the battery from the Velcro mounting pad.
Install the new battery onto the Velcro mount pad, remove the battery
protector caps, plug the black wire into the black terminal, plug the
red wire to the red terminal, and reconnect the leak detector power
supply. Allow 24-hours of leak detector operation time before testing
the new battery.
