Solar Powered AA Battery Charger by SunForce. Works well. Guy Fanguy, Houma Louisiana.

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.

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

I recently bought a solar battery charger that doesn't have a meter built in. But I do have a multimeter that I use to check the battery's voltage and current. But I want to make sure my batteries don't overcharge and possibly explode. So I want...

The heat of your solar panels doesn't mean anything - other than the drop in efficiency from them being warmed by the sun.
If the panel is match to the voltage of the batteries, then you can't over charge them - the current just turns to...

I'm thinking about going camping for an extended period of time. I want to bring my camera but I won't be near an electrical outlet to recharge it's AA batteries.
From what I've read solar powered rechargers are impractical because they...

Hi, I have lived "off-the-grid" (in the mountains without electricity) for many years. I know about the wind up chargers and solar and such, they do work, but it is a major hassle, will cost you money to buy it, & you will have to carry

The blinds are so high and the batteries need to be replaced just about every six months. I would love to just put some sort of small solar panel to power the battery pack now. It uses 4 AA batteries. If I could some how incorporate a charger...

It might be considerably more economical to simply run longer wires to put the battery pack in a more convenient location. Four batteries are about 6 volts. You would have to replace the batteries with NiCad or other rechargeable cells, which...
