Lucent Technologies Enhanced VR Series Batteries

Issue 5  December 1998 

Discharge and Power Data  9 - 13

High 
Discharge Rate 
Performance

The Enhanced VR battery is also appropriate for applications 
requiring high discharge rate performance. Table 
9-G lists 1-minute and 5-minute rates to 1.75 volts per battery at 
77° F. These data have been adjusted for intercell and/or interior 
connector losses, but not for connections between the battery 
and the load.
