AC300 battery maintenance

The AC300 manual says to discharge the batteries at least once every 6 months. Does that mean a full discharge to 0% or is there some other percentage I should shoot for? I am using the system as a UPS (my devices are plugged directly into the inverter, no transfer switch) with the default setting of Standard UPS/Offline UPS.


Hi @glc650 , Yes. Completely discharged means that the machine is drained of power until it is turned off.

Does that happen right at 0% or does it reserve some juice and shut off a little before?

Hi @glc650 , You can discharge the machine to 0, then fully charge it.
