2.0 Description
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.
