There are newer LFP portable batteries with <10ms UPS switch times that charge quickly and have much longer battery life’s, and LFP cells don’t degrade the same when kept at 100% like other types, although you should still cycle them a few times a year.
Bluetti makes some, the elite series has their latest UPS features. The non elite are slower and noisier.

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.

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

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.
