    UPS batteries need to be fully charged all the time. Lead acid batteries like to be fully charged. Lithium batteries need to be stored around 50% charge to have a long lifetime.

      Lead batteries are also cheap.

      And mine take ~30 minutes to charge. This person may want to replace their batteries.

        It’s brand new, I’m reading directly from the instructions, if it only takes 30min to change they should say that and it’s not by design. It’s a CP1500PFCLCD

        Charge time depends on the UPS. The cheap consumer grade ones usually have a float charger that takes forever.
