2.3 Recommended Battery Operating Limits for High AC Ripple Applications

The battery maximum operating limits are specified for DC current and voltage and do not account for AC ripple typically caused
by frequency conversion electronics such as inverter/chargers. The following operating limits are recommended for these types
of systems.
Recommended Operating Settings
Continuous Charge Current
Continuous Discharge Current
Charge Voltage (Bulk/Absorb)
Charge Voltage (Float)
Low Voltage Disconnect
