Charging recommendations:
Broadly speaking, a battery may be
recharged using either a constant
voltage (CV) charger or a constant
current (CC) charger, or a modification
of either or both of these.
The exact regime chosen generally
depends upon the time and economic
constraints imposed by the system.
Constant current charging is widely
used in cyclic applications where a
recharge must be accomplished in a
relatively short time period. Constant
voltage charging, where a single
voltage level is applied across the
battery terminals, is the most suitable
method to recharge CYCLON
batteries. Depending on the CV
charger's current limit, it is possible
to recharge these batteries from a
100% discharged condition to better
than 95% state of charge in less than
one hour, using only the cyclic charge
voltage.
Constant voltage charging
Constant voltage (CV) charging
should be within the following ranges:
Fast Chargers, Per cell:
2.45 to 2.50 volts @ 25°C
12 volts:
14.70 to 15.0 volts @ 25°C
(for a maximum of 16-20 hours)
Float Chargers, Per cell:
2.27 to 2.35 volts @ 25°C
12 volts:
13.62 to 14.10 volts @ 25°C
To avoid thermal runaway in warmer
temperatures, and to improve charge
acceptance in colder temperatures,
the charger voltage should be
compensated by approximately
3 millivolts per cell per degree
Centigrade variance from 25°C.
This is a negative coefficient, with
the voltage being lowered as the
temperature increases, and vice versa.
