I built a homemade one. 2.4kwh of capacity.
Should be good for a few decades easily.
Wouldn't call it cheap. But, it will be around for 15 or 20 years.

I've had my APC 1000-UPS for 5 year and have only had to replace the battery once, though I think I may need to again by the end of the year.
Do you remember what brand of battery it was?
I think the original lasted longer than the replacement.
So, every ~2.5 years... Not that far off...
if you're running batteries down often enough to need battery replacements that frequently, you may be going 'too cheap' (poor quality and/or not enough capacity) to begin with, and would need an upgrade not another 'cheap' solution.
Maybe this is a combination of cheap battery and temperature. I feel the chassis is a bit warm.
Mains is very stable here, only very short breaks like fractions of a second. So no deep cycle.
Thanks!
