The usual scenario for telecom site batteries is design for long float life with perhaps a dozen or so major discharges. But long term survival at low voltages isn't in their job description.
Paying up the yangying for a lifeline means getting incredibly thick plates. Controlled overcharging sheds substantial amounts of plate material. But if they're super thick it's like having a checking account overdraft protection plan.
But the chances of survival for a battery with lesser thickness plates is less.float maintenance for 10 years will consume a chunk of plate layer as well.
By the way Don if you ever get your hands on a regular transformer rectifier battery charger you can throttle it with your variac. A Fred Flintstone grade sort of adjustable charger.

Hi Mex,
I do have a regular transformer rectifier Battery Charger. I wanted a variac before I got the autoformer.
If I were to yin yang I'd go for Sio2. The problem is my age.
The existing jars don't owe me a dime.
I will ask my cousin to load test them later this month--and will base my decision on the outcome.
Regards, Don
My ride is a 28 foot Class C, 256 watts solar, 556 amp-hours of Telcom jars, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

I've yet to stumble across a conversation that mentions which brand of lithium battery is a standout; survival or cycle wise. That might have to do with the actual weight of each module. It would be hard for me to swallow "a cell is a cell" when it comes to lithium. Unlike western economies I am unable to dig up much information on the subject of China and lithium battery manufacturers. The small experience I have with another type of lithium. Battery is rather sour.
Replacement batteries like for my ereaders use reclaimed cells. Lifespan is less than half of a new battery. The sales pitch though is outright fraud. Keep in mind this is a different type of lithium battery to begin with.
Until LTH starts making lithium batteries here in México I am leery of going automotive size lithium. For solar the Tesla wall pack looks entirely legit. I need more factual info.

Canada just won the bidding war for VW to build their new battery plant in Ontario. does Mexico have any Li mines? that's where the plants are going to be built, close to the natural Resorces and the automotive industry.
the tesla wall is legit, but man is it expensive. I am getting quotes right now to do solar on my house, but I had to pass on the tesla solar wall.

Hi all,
I got a chance to load test the battery bank.
one set (each 139 amp-hours) was doing 350 amps
the other pair did 550 amps.
I think it is safe to say they survived.

Good news indeed, is the second pair a higher capacity rating than the first pair, 550 to 350 is a big difference, if all 4 are the same rating and same age, then the first pair is not in the same condition as the second pair, but not a total loss
I can explain it to you.
But I Can Not understand it for you !
