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

    It makes sense to me to have low power chargers on a UPS. Once your power comes back online, it needs to deliver enough juice to power everything plugged into the UPS plus the battery charger. A fast charger would be more likely to trip a breaker.
