VRLA CONSTANT CURRENT CHARGER
When using a constant current charger it is important to adhere to the termination
criteria mentioned below to minimize the chance of excessive over-charge.
See Table 5 & 7 for the recommended constant current charge profile.
VRLA REFRESH CHARGE
If Rolls VRLA batteries are properly charged they should never require an
equalizing charge. If they were not properly charged and there is a decrease

apply a refresh charge as follows:
NOTE: Current controlled chargers are very expensive and often not
available. Currently, 100% of all charging devices used in the Renewable
Industry are Voltage Regulated.
