Charge

Correct charging is one of the most important
factors to consider when using valve regulated lead
acid batteries. Battery performance and service life
will be directly affected by the efficiency of the
charger selected. The basic charging methods are:
Constant Voltage Charging
●
Constant Current Charging
●
Two Stage Constant Voltage Charging
●
Constant Voltage Charging
Charging at constant voltage is the most suitable
and commonly used method for charging valve
regulated lead acid batteries. Figures 8 - 13 show
the charging characteristics of Powerline SC when
charged by constant voltage chargers at 2.275
volts/cell, 2.40 volts/cell and 2.50 volts/cell when
the initial charging current is controlled at 0.1C
Amps and 0.25C Amps.
Figure 7 shows one example of a constant voltage
charging circuit. In this circuit, the initial charging
current is limited by the series resistance R1.

Note
The recommended float charge voltage for
Powerline SC at 20 C is 2.275vpc ±0.005v. this
should be the measured average for the total
battery, however when measured within a battery
network or string the allowable tolerances can be
expected between 2.25vpc to 2.30vpc.
