Charger mod

[tattoosteve99]

Hello its been quite awhile since I posted here but Im back! So I have an idea that maybe some of you can help me with. I want to make an adapter to charge some 14500 batteries with my ultrafire charger. So here goes
Charger=http://www.lighthound.com/Ultrafire-36-volt-or-3-volt-RCR123-Lithium-Battery-Charger_p_2270.html

Batteries=Westinghouse 3.2 volt lithium ion rechargeable...dont know if they are protected or not?Got the at Walmart 4 for 10 bucks.

Holder=http://www.radioshack.com/product/index.jsp?productId=2062247
2 of these.

I was thinking that I could make an adapter that would plug in to the existing ports on the charger, and then switch it to 3 volt and then charge.
Any ideas that this will work?
Thanks

Hmmm ... Westinghouse 3.2 volt lithium ion rechargeable

I'm a little concerned about those batteries you say you got at WalMart . Are they AA size cells ?

You'd better wait for some experts here to weigh in on this .

In the mean time - give some more details on those batteries and the Voltage and mA output of your charger ... for them to help you.

3.2V isn't all that common - usually that would suggest LiFePO4 chemistry. If the cells have some more info like 3.6V cutoff for charging then I'd be pretty sure that they are LiFePO4 cells. If this is the case then they would not be protected, but they are 'safe' from 'thermal runaway' or 'vent with flame' (explosion).

LiFePO4 cells should be OK to charge on that charger when switched to 3V.

Mr Happy checked out these cells a while back in this thread. The WF-138 should work fine to charge them, if you rig up an adapter.

Using those adapters you shouldn't have any trouble charging the westinghouse 3.2v cells as long as the max charge voltage is around 3.6v.
I have been using a bench power supply set to 300mAh CC/ 3.6v CV and stop charging when the current drops. I got most of my information from Mr Happy's thread too. :thanks:

I have been using these 14500 cells with great success in my Quark AA. Turning that little light to MAX always makes me . They are indeed LiFePO4 and relatively safe. Charge 'em up and enjoy!
