Aa Solar Charger

You might try the solar powered yard lights. Mine use two double A batteries each. I have four. I don"t know if there are yard lamps that use triple A.
Good luck
Hope

Went looking for a Solio Classic but came across this. What this unit does is charge your AA NiHM (included) and from there you can charge any ...

I am building a solar AA battery charger but have a problem my solar cell is 23-25 volts @ 120mA. I only need to charge to AA's(2.4v). What kind of voltage regulator should I use? Thanks

Solar cells have a high output impedance, which tends to produce a constant current. A constant current is one way to charge a cell.

So why not connect them together? I don't think you need a regulator.

I am going on a camping trip for a week and will be regularly charging aa and aaa batteries in my car charger. I am wondering- will getting one of those 12v solar battery chargers that you plug into your cigarette lighter that keep the battery...

try this addy www.realgoods.com they should have what you are looking for and other info solar related.

We have a yellow solar battery charger which has the Shell (petrol station) logo on them, it charges two AA batterys at a time and we are really impressed but we don't know were it came from and we would really like another one, can anyone help...

You could probably find one on E-Bay :)
But my sister got one from Woolworth's i think.
I'm not sure if its run on solar but if your ever on the computer then you plug it in and it uses that energy.
Also im sure you can buy...

Hi. I have bought a number of solar panel chargers over the years. Some are for AA batteries. Some are for AAA. Some are just for a specific device. How do I combine all of them together to create a single, more powerful or faster charging unit? I...

First you need to figure out the output voltage of each charger. The AA and AAA chargers should have the same output voltage. Each solar cell will generate 0.5 to 0.55 volts per cell. So count the number of solar cells in each panel, if they...

I'm trying to make a solar charger for when I go on camping trips. I know you can buy them, but they're about $70, and I just purchased about 8 cells for $25. I plan on wiring them in parallel/series to get the desired voltage and amperage, but I...

4 AA's is about 5-6 volts. so you need well above that to charge them, assuming they are in series.

It's a complicated area. Yes, there is a risk of overcharging. And I don't know the current output of the cells, or the type of...
