For systems without such a device, it is recommended that the float voltage be reduced by 3mV/°C/module for the 2VR250E or 2VR375E and 6mV/°C/module for 4VR125E or 4VR125EL for temperatures above 25°C (77°F).

  • Page 44: Charging Voltage Ripple

    Both the amplitude and frequency of the ripple affect the degree of battery degradation. As a guideline, the charging voltage ripple for the Enhanced VR Series battery should not exceed 10mV peak to peak per cell or last longer in duration than 8mSec.

  • Page 45: Capacity

    Lucent Technologies Enhanced VR Series Batteries The Warranty Period outlined in Section 12 is based on the battery temperature, not the ambient temperature.
