Does anyone know of a good AA, AAA battery charger? I have some lithium 3.2V Lifepo4 AA batteries and would like to have something on hand to charge them.

Thank you

Check out deal extreme,they have many different chargers.
Thank you. You know if there are any that can actually tell you when the batteries are charged? I guess Lithium batteries can't use regular battery chargers... Don't know anything about them.

Mine has red and green lights on it ,the green light is full charge. I use 18650 batteries for several of my flashlights.
Me too. But they are 3.7 (4.2) volt batteries. Putting that type of voltage on a lower rated battery causes them to go boom.

What ever you get make sure it's not only right for the voltage but the type of battery too.

I posted the one link in the 'cheap' flashlight thread but here you go.
http://www.lighthound.com/Solarforce_c_168.html
http://www.sbflashlights.com/cart.php

I got the Solarforce (L2). Not a true flashlight per se (sold as a host) because you need to order the lamp (drop in) too. That way you get to choose what intensity led you get.

I got two of them and the XM-L lamps;

http://www.sbflashlights.com/Solarforce-Dropins/Solarforce-3-7V-1-Mode-Cree-XML-Dropin-p131.html

The batteries I chose are the Panasonic 3100 mAh with added circuit protection sold by other brand names like Callie Kustom, Redilast
or Xtar;

Those some expensive batteries :eek:

Wonder if it would be easier to just buy a charge that had overcharge protection? Dunno much about it. Still lookin' around. Thank you for u're input m8.

They'll work, sort of.

Everything is bottom tier.

As said repeatedly **** fire is cheap stuff and seldom what's the advertized rating. That goes for Trustfire, Truefire etc. I've gotten some batteries fron deal extreme rated as 2400 mAh 'Trustfire that were heavily used, probably recycled, relabeled, laptop baterries. And not worth the cost of the free shipping.

Cheap flashlights that work for a while but have really cheap switches that may or may not work every time.(ask me how I know)

Granted the stuff I linked to is more expensive but tried and tested. Even recommended by those that collect real expensive flashlights at the CPF forum.

Yeah, my only concern was the charger you listed says:

- Output 2: 4.2V/4x500mA, 500mA (+/-10%)

And didn't know if putting 3.2V in there would ruin them or not. Yeah, 3.2v not 3.6. Had to double check the batteries.

Ever hear the phrase you get what you pay for?

I've tried cheap batteries and flashlights and was disappointed. If you want cheap and local flashlights go to Home Depot and get their 10/$10 (with aaa batteries). At least they hold up for a while. The led lights aren't great but fine for many applications.

3.7 volt batteries peak out at 4.2 volts. But sold as 3.7 as an average. They can be drained down to at least 3.2 (I think lower but not positive where they eventually cut out.)

I don't own any 3.2 volt batteries but I'm positive they won't work in either of the chargers I linked to. It should say on the battery what the maximum voltage it can take.

Charging above the maximum voltage is a great way to start a fire. More Lithium ion batteries explode while in the charger then any other way. That's why the charger is more important then the battery.

Great anyway! I will be buying the 3.6v that I listed then. Those should work with the chargers you listed then. Thank you very much.

Thanks everyone. I think I'll go with this:

Light:
http://www.dealextreme.com/p/ultraf...e-led-memory-flashlight-black-1-x-18650-91091

Charger:
http://www.dealextreme.com/p/trustf...500-16340-17670-18500-18650-ac-110-240v-66842

Batteries:
http://www.dealextreme.com/p/rechargeable-3-6v-18650-2200mah-blue-933

Anyone know of a good solar charger for these batteries? I thought about buying some cheap walmart solar lights that you put outside and charge them that way, but would probably take a month to fully charge one LOL. Any ideas?

Thanks
