Since batteries are so important to an off grid home electric system, I finally got around to looking up info on DIY battery options. Fascinating stuff.

First up, changing a dead lead acid battery to a working alum battery. John Bedini came up with this DIY protocol, apparently.

http://www.hho4free.com/bedini_alkaline_battery.htm

Any thoughts on this? It seems to have advantages, if the information is true. I'd just like to get your thoughts on these methods.

Next up, speaking of Bedini, is the pulse charger he sells.

http://energenx.com/products.html

So, anyone believe the claims of rejuvenateing old batteries by pulse charging with Bedini's charger? Anyone use or know someone who uses this charger? Pretty expensive, but if used on a home battery bank to extend the life, and it works, it might be worth it.

For the truly hard core, this next link is instructions to build your own batteries at home, Edison batteries included

http://members.shaw.ca/Craig-C/hybridize/BatteryMaking/BatteryMaking.html

This guy is flat out amazing, whether or not you agree with his conclusions. He's experimenting and sharing his results, along with providing directions to build Edison Batteries at home---free of charge. Right or wrong, this guy knows a thing or two about what it's going to take to change the way things are currently headed in this world.
He's not claiming he knows more than battery manufacturers, just that he knows enough to help you build a better, longer lasting battery that manufacturers are unwilling to provide for sale.

And then there are the earth batteries. Next link is to an extremely interesting little project I'm going to do with my children.

This little battery is pretty cool when you consider it's life span compared to a AA battery's. I don't see these ever running a home, but it seems possible to charge small electronics with them or light enough LEDs to see by night, with a bit more development.

Anyway, hope some of you find the material in the links interesting. If you know something about any of this, please share. There doesn't seem to be all that much info on building batteries with a useful amount of power on the web right now. Or, maybe I'm not searching with the proper key words yet.

To clarify Edison's batteries. http://en.wikipedia.org/wiki/Nickel–iron_battery


NiFe batteries. They are not maintenance free. But if you do spend some time on them they will last indefinitely... as it stands to the current date. They are on the market today. China produces NiFe batteries for the US market. Edison's batteries are still at full capacity after 90-odd years.

The principal of Edison's batteries are that the electrolyte is in itself the anti-oxidant for the anode and cathode. Hence you avoid the issues of lead-acid and it's sulfication - they are simply not relevant in the NiFe battery. There is no build-up on the electrolytic plates within the battery. The electrolyte solution has to be changed to maintain capacity however.

Battery desulfation might help to prolong a battery life that is sulfated. The pulses to the battery can mess with inverters and solar chargers. If you take care of a battery you can keep down the sulfating and get a good life out of your batteries.

I did try a few desulfation devices when I first went off grid. I ended up destroying the batteries because the solar chargers were unable to read and adjust to voltage because of the pulses.

Any time you look into battery chargers look at the power factor and the harmonics they give off. When you run a battery charger off a genset most of the time you need to double or triple the input amps when sizing the genset. The low power factor and harmonics will kill the coils in the head if it is to far out of spec.

The chargers built into the better brands of off grid inverters were made to work with gensets. They have a different design.

My current battery bank on my off grid system are 9 years old and still in great shape. It comes down to proper sizing, maintenance, and not abuseing them and they can last 15 to 20 years. I love my wet lead cells.

I gave up on the thought of having a back up genset. It's much cheaper to have a alternator on a small engine than it is to run a larger engine. Cheaper to repair, replace, and to fuel.

Pulsators work good, if the plates arn't actually shorted out.

Get the one that varys the pulse rates, it will shake off a lot more sulphides.

Best idea is to run these off the wall, or in the car, since it is running all the time.


Battery Minder plus i believe.
These will run the desulphation magic, even when not hooked up to a charger. Does drain slowly, figure a week before you have to hook it back up.

And here is even more news...dang, it's the same thing.
