If SLA and Li Optimization are set to Capacity (see Saving Program and Target Capacity
Settings, page 79), the charge time is extended for approximately 20 minutes after End of
Charge has been reached. This additional charging period may add 4% to 6% capacity;
however, the small increase in capacity may not be worth the additional time.
If SLA and Li Optimization are been set to Time (this is the recommended setting), charge
will terminate as soon as End of Charge has been reached.
In both cases of Optimization settings, exceeding dT/dt will fail a battery.
Stage 3: After the charge has completed, the battery is maintained at a constant voltage
level (this is voltage is the Maximum Standby Voltage set in the C-code).
