I have a few of these and the batteries all died. Any recommendations on where to buy batteries or is it even worth it?
You can use lithium batteries that will last a lot longer, but the charging profile won't be correct so you wouldn't get full capacity out of them.
I did this on one of my systems and it's been fine for about 8-10months
Or you can opt for a goldenmate lithium UPS. I have one of the pro models and have had one short outage and it worked fine but it doesn't output munch info to my Linux server regarding consumption/voltages...

I got tired of replacing my batteries every couple of years and the short Op time due to the smaller capacity so I went with one of those lifepo4 power banks. I have a bluetti elite that can run for hours vs 10 minutes and it only cost about 2x more. The power bank is also pure sine wave and can take solar panel inputs. Easier to integrate with my home assistant too.
If you are talking about replacement batteries for a ups that are lithium, it would depend on the model. Just find a lead acid replacement and make sure the new ones are the same dimensions and terminal location.
For the goldenmate, this is the one i have https://www.amazon.com/dp/B0DQ4RH...nmate&th=1
There are less expensive options if you dont need it to send a power down signal to a computer/server

a great option. Just make sure it has fast enough switching to be used as a UPS.
I tried going down this route with an ecoflow delta 2 and switching was too slow (its not advertised to be used as a UPS, so its not its fault). It seems like most new power banks have the ability to be a UPS now, but just something to double check. (10ms or less switching speed)
