Yesterday, I scored 26 FREE big-a$$ UPS batteries that a cable company was discarding.
Here's the tally after a session with the voltmeter:
22 Good batteries, all over 12v :-D
1 @ 11.6v, easy fix ;-)
1 @ 4.2v, might save it (very likely)
2 @ 0.05v, might be totally shot? IDK for sure... ???
Overall, a Great Haul!
:-D
Pushing the 4.2v battery on a standard charger, but the 11.6v battery is getting the "Spa Treatment" with the R-Charge radiant charging unit. It uses High Voltage DC spikes to "condition" and "rejuvenate" the cells. It eliminates sulfation and makes the lead plates more porous and spongey, which allows a greater ampacity. They also tend to charge quicker as they become "rejuvenated" and can hold up to 25% greater ampacity, and ergo, run times. A 100AH battery taking up to 44 hours to charge with this method actually means I need a bigger unit. Stop It, Dirty Minds! LOL!!! I mean that I need a more powerful Radiant Charging Unit, so I can do many of these batteries at once. But they get rather EXPENSIVE! I might get a twin unit that is rated at 4 times the output, but that will have to wait. I can build one, but automatic cut off would be the problem. Hate to waste a whole batch of batteries because the charger did not shut off! Here's a pic of my R-Charge unit:

Great to hear that it was overall a great success!

Next Moves: Get a couple larger inverters (or several medium sized ones, or 1 large, a few medium) and set up UPS stations for critical power. Like the fridge, gas furnace blower and so forth. Oh, and my 'Web Connection' LOL!!!

Cant forget the web connection!!!! Sounds like a good set up man! How much space does it all take up?

Each battery is about 12" x 6" and ~8" tall, so not bad. I suspect I will go with 3-4 smaller setups around the house, I can get away with a power unit the size of a small suitcase I'd imagine. Looks like the 2 totally "dead" batts will likely be recycled, but I still need to try the old "Bump Charge" method... ;)

All the batts would take up ~13 sq ft minimum, and more most likely, as I would make some funky connections to reduce the wire size needed to carry the Big Amperage. Also, using Copper Tubing is a bit more efficient, cheaper and allows higher current. It is hollow so it cools a bit quicker than insulated wire. But precautions and barriers must be used to avoid a short circuit! Fire Hazard WOW!!!

Doesn't sound too bad space wise! This is pretty cool stuff man and you certainly seem to have the knowledge and wherewithal to get it done!
