Hawker Energy , 6V Ah lead acid battery 4533 4533 Fiche De Données

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 (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.
