I second u/seth’s recommendation on Will Prowse as a good source of knowledge on this topic. I agree with avoiding lead acid as it’s less cost effective for a long term solution. I think they also have some more maintenance involved with them compared to li ion.
Yeah, I guess you could recondition one kinda like how this guy does it. I had never heard of doing that before. Thanks for the info.
I would still opt for li ion even with that though. Lithium Ion has a 2x greater depth of discharge(usable stored power) and 2-3x the lifetime (not taking into account any reconditioning) when compared to lead acid. That equals 4-6x the utility theoretically at around double the cost. That would make li ion 2-3x more bang for your buck compared to lead acid.
But there may be some case, for using a cheaper lead acid on a small scale project. Just be aware of the maintenance requirements of them and the increased cost if you do end up using it on a long term project.
I’d probably go with a renology battery via amazon or an eg4 battery from signature solar or from solar sovereign for lithium Ion batteries for long term use.

Don’t the lead-acid have better longetivity tho, since you can change the acid?
The acid is not the problem. It’s the sulfation of the plates (or mats) in flooded cell (and absorbent glass mat) batteries that ruins the batteries.
