Can I recharge protected CR123a's with an adapter?

Hi, I got a few rechargeable lithium CR123a batteries.  They are the protected kind.

I was wondering if I can just find some adapter in the 3.6 volt range and charge them that way??  I had this idea cause it says protects from over-charge, over-heat...and such.

Can I do it?  if so, what ma or volts should it be at?

I don't mind soldering together a board for it, I just want to know the simplest solution for charging these things without taking them out of my module.

Re: Can I recharge protected CR123a's with an adap

I would highly recommend that you treat the Li-ion batteries with care and respect. These things can and will "rapidly vent with flame" (explode) if they are mistreated.

It sounds like you are using more than one, so you would need a board to moniter the voltage of each cell and cut out at the appropriate voltage for your cells. Don't depend on the battery board alone for protection - get an appropriate charger.

Do a search on CandlePowerForums for Li-ion explosions for more information.

DX has chargers cheap so i wouldn't bother ghetto rigging a charger when a retail one is like $10 :-/

I know that lithiums explode! and I have a charger!

But I just wanted a way to charge them inside the unit instead of having to disassemble it for each charge.

So exactly what does the board in the battery do then?

I'm pretty sure it protects against over and under-charging.
