Bringing some dead batteries back to life BatteryMINDer Model # 2012
He did a good review of model #2012. Works for me. I prefer to buy USA made if possible, and buy direct, as opposed to buying from Monopolized middlemen like Amazing.

Knowledge base on maintaining batteries - excellent choices - http://www.batteryminders.com/knowledge/
I have this model 2012 permanently installed under the hood, I do not like removing items that can be permanently installed. It is fully sealed case which is waterproof and has temperature compensation in environment from 0F to 130F. It is a good model, made to be permanently installed and functions very well. I've a 110VAC 15 Amp Marinco external plug installed into a drilled with hole saw in side of auto, the Model 2012 is permanently wired to that plug. I plug my auto into home power when I need to, it is also switched and can use Solar Power 500 Watt Sine Wave Inverter. It works both ways and I call it good. I am NOT affiliated with seller, I just like their products.

The most reliable batteries are likely to be lithium polymer type... I looked up a listing just now to give an idea of what these are like and the prices... They are quite expensive but as long as they are kept charged up, there is no reason they can't last 30 to 40 years....

https://www.ebay.ca/itm/Lithium-12V-100 ... :rk:1:pf:0

Remember: A 100 amp / hr battery can only produce 100 amps for 1 hour... 50 amps for 2 hours, 5 amps for 20 hours... you still need to produce power on a regular basis or a battery of any type will deplete quickly. Lead acid batteries that are discharged completely become damaged. This is also true of other battery types but to a lesser degree.

Really, I posted the Rolls-Surrette for the battery maintenance PDF chart to give an idea of how to go about upkeep.

Use & deep cycling aside. I agree with you there, both flooded & sealed lead-acid AGM, or sealed lead-calcium PureGEL, majority of batteries should only be depleted by 50% or battery is killed or its life will be shortened. I chose lead-calcium PureGEL sealed maintenance free. I just came up at end of 2 years using the $760.00 pair = 400Ah from 2 paralleled 200Ah. (today cost is $880)
So far, 200 Ah has been enough (don't need an AC unit) to power 100% of my electrical cooking, morning heat or tool toys for the job & leisure occasional movie or ??? Usage timing is everything.

Lithium can be drained down to 10% & I'd love to have them, but I won't afford Li's. The cost is way too crazy high, for now. After these batteries slow down I may consider Lithiums, when meeting at that crossroads...

I often hear from others, "your first batteries you will kill them." I disagree, if you start out with the right equipment, temperature & other VDC monitoring & use meters - fuses and all that, and use Ah correctly they'll be fine. The real problem is when people forego and try to cut costs by not buying what they really need for a reliable system. Wiring, is another pet peeve of mine. Wiring has to be done right, no skimping. I'd be happy to trade good company & a good meal for my wiring skills & time.

Thanks for posting the chart, that will come in handy later... I have looked at the pure gel batteries in the past as a alternative to lead / acid for my car but didn't look into them for off-grid situations before. I like the temperature stability of the pure gel batteries and as you have pointed out, you get 400 A/h for $760.00 and the best Li-Polymer set I've seen so far would be 300 A/h for around $1,200. I believe I will be keeping an eye out for deals on the pure gel type now.

If I really get stuck, I can always use the graphite rods I bought, aluminium and salt water to make a battery.... The graphite can be used forever but the salt and aluminium gets used up. Obtaining a cost effective battery array would of course be preferable to that.... LOL

I did oversimplify the problem in my post and I thank you for pointing out the missing information Andy. I need to try harder to think of other people's set-ups and situations and their needs rather than my own plan. I could never get away with 200 Ah worth of energy per day as I run an indoor gardening cabinet 24 hours a day and I would run out of electricity in about 14 hours from full charge. After I expand my garden, I will be using 3 times that amount of energy. I am one of those that needs to produce power all the time but a battery array as a buffer would be really awesome.... :D
