I NTRODUCTION
The H-491198-01 Nickel-Metal
Hydride (NiMH) Battery Charger is
a dual power source battery charger.
It charges 4.8 volt 220 mA NiMH
batteries and is powered by
85-264 VAC line power or 12.5 VDC.
The H-491198-01 Battery Charger
uses a -(dV)/(dT) negative delta V
technique to determine when the
battery is fully charged, which is
typically two hours. 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. The front face of the battery charger displays LEDs that provide the
operating status. The battery charger connects to the device being charged
through a short cord terminated with a power jack.
