TIPS ABOUT NICAD BATTERIES
Nicad batteries may accept as many as 1,000 recharges;
however, they have some limitations.
1. Nicad batteries will only last about half as long
as standard carbon-zinc batteries before
recharging is required.
2. Nicad batteries may develop a “memory” if
you give them repeated “booster” charges. In
other words, if you charge your Nicad batteries
over and over again for only three 3 hours at a
time, the batteries will eventually only hold a 3-
hour charge.
3. Nicad batteries may reverse polarity if
discharged too low and refuse to recharge.
Don’t leave your detector turned on, and don’t
continue to operate it after the “LO BATT”
indicator starts flashing.
AUTO RECHARGER
The complete IMPULSE recharge kit (optional) includes one
battery pack, eight Nicad batteries, one 110-volt, 60-cycle
home recharger and one 12- volt, negative-ground, auto
cigarette lighter recharger. The 12-Volt Recharger offers a
method to recharge your nicad batteries while on the road.
1. Remove and disconnect the Nicad battery
pack from the Control Housing.
2. Connect the cigarette lighter recharger
battery lead to the battery pack.
3. Plug the recharger into the cigarette lighter
socket, and the batteries will immediately begin
recharging.
4. The small, green light may glow briefly if the
batteries are completely dead and the engine is
running. Normally, it will not glow at all.
5. An overnight charge with the engine off may
give only 6 to 8 hours of battery life. A full charge
may take as long as 48 hours (less with the engine
running). For this reason, the Auto Charger may
best be used for occasional “Booster” charges
(see Tips).
6. Do not charge over 48 hours.
