I NTRODUCTION
The 491198-36 NiCd Battery Fast
Charger is a dual power source battery
charger. It charges 3.6 volt 1400 mAH
NiCd batteries and is powered by 120-
240 Vac line power or 12.5 Vdc. The
491198-36 uses a -(dV)/(dT) (negative
delta V) technique to determine when
the battery is fully charged, typically one
hour. With this technique, the charge
state of the battery has no effect other
than shortening the charge time.
Housed in a rugged enclosure, power enters the battery charger through a power
entry module, which contains the fuses, or an optional cigarette lighter plug
adapter. LEDs and the label on the front face of the unit provide operating
status. The battery charger connects to the device being charged through a
short cord terminated with a power jack.
An integrated circuit within the charger monitors the battery voltage and controls
the charging functions according to the charge state of the battery.
