We've pretty much switched all of our batteries out for SunXtenders.
We've had them in a couple of solar sites for over 6 years. That's daily
charge/discharge cycles.

An alternative if you want a high quality AGM Group 27 100 Ah battery,
there’s a place in Texas selling Sun Xtenders for $280 incl shipping:

I recently bought the same batteries but paid around $300 at a local
Concorde dealer where I could pick them up rather than deal with
shipping. They have thick plates, full spec sheets, and M8 copper
terminals, and are made in the USA. I really hate replacing
batteries, so I’m willing to pay more, whether they will last 3 times
as long I don’t know. But it always seems batteries sit there for
several years and then fail right about the time we get a big power
outage during a storm.

It says 200mins at 23amp.....that would be around 75ah. So $1/ah.
Seems pretty cheap.
A regular lead/acid wet cell is fine if they're kept in perfect
conditions....ie never discharged and kept at 70F. Otherwise they'll
stratify and the plates will get sulfate built up on them and/or corrode.
They say you can get more out of them if you top off the fluid and
shake them up.
AGM is reported to last 2-3x as long when conditions aren't perfect
because they resist these bad things happening.
On the other hand, I have a feeling for some WISP loads that if you
buy the batteries big enough you won't really notice how weak they are
getting until they're dead. Such as if you have a few canopy AP's and
a Mikrotik totalling 40 Watts, then two of those batteries would last
you over 40 hours when they're new......and if you still get 5-10
hours out of them when they're near end of life,then they're still useful.

How long do these last vs AGM?

That's a similar price to what I've seen locally here at Menards and
Farm and Fleet. It's not a bad way to go if you just want lots of
capacity for cheap, but I think most people prefer AGM batteries.

Saw these at the local Fleet Farm. Are they a good deal?
