SLA, Li-ion and Li-Ph Batteries
The C7x00 analyzer uses a Constant Current/Constant Voltage Charge algorithm
to charge SLA, Li-ion and Li-Ph batteries. A current and voltage plot is shown for a
typical Li-ion battery serviced on the analyzer with default C-code settings. This plot
is similar for the SLA battery.
There are three stages during the charge:
Stage 1: the battery is charged at a constant current (this current is the ‘Charge Rate’ in the
Extended C-code) until the battery reaches the Maximum Charge Voltage (set in the
Extended C-code) is reached.
Stage 2: When the battery reaches Maximum Battery Voltage, the analyzer switches to
constant voltage. During this stage, current is reduced to maintain Maximum Charge
Voltage until the End of Charge current (set in the C-code) is reached.
