3.6V LIon?

#1 09-11-2003, 11:09 AM

I have two button-cell 3.6V LIon batteries. they're about the diameter of a quarter, but thicker. While I'm sure my M/S could handle 3.6V, I'm more concerned about charging these batteries up. Does anyone know of a good 3.6V LIon charger?

and whered you get button cells at that power rating that are recharageable?

If they haven't purged some REALLY old posts, you can do a search for more info on them. Way back in the day (lol okay about a year ago), "Able Energy" was all the rage here in the tinyrc forums. They offered button cell batteries in Lithium, lithium ion, and a few other compounds. The Li-ion cells came in LiR2450 and LiR2477 form factors. I have one of each.

The specs, mAh rating, max mA output, dimensions and weight are all very nice. Not too big or heavy for a tinyRC at all.

Here's a spec sheet I scanned a long time ago. check out the numbers for yourself. Click the thumbnail for the fullsize scan (beware, it's HUGE):

here's some more info... it's not "able energy" - it's "Able battery" and their website is FINALLY back up.

Here's a previous thread about the batteries:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 actually im sure if recharable but old gameboy color games have 3v lithium battery(to keep the game saved and it was a 3v in mine) but i cant get much voltage out of it and i cant charge it cause well no speacial charger. but if im right and you have a old cruddy glameboy game lieing around smash it open! and you have a dual cell(if you have the irght charger and my therory of them being recharable is correct)

who's interested in some of these? I have the opportunity to buy some for pretty cheap, but I don't know how much shipping is going to be from asia... The more I can buy at once, the better. Keep in mind you'll need a charger to recharge these. They won't be fast charging.

DO NOT TRY TO CHARGE A LITHIUM BATTERY. only Li Ion or LI Poly are rechargeable, you could cause a fire trying to charge a regular Lithium battery.

I posted about this about a year ago, I've just finally got the ball rolling.

These batteries are lithium ion. They require special charging. The charger sold here at tinyRC should work just fine. The chargiong procedure for Li-Ion and Li-Poly are identical, and any smart charger capable of charging 3.6V cells will work.

Primary (non rechargeable) Lithium batteries work GREAT in tinyRC's. I have a 3 volt primary lithium cell I use in my microsizer for drag racing, you just can't try to recharge it, so it gets expensive.

Basically I can get them for about $5 each if I order 10. I'd like to make a LITTLE profit on it, but I am more for helping my fellow hobbiests than making a wad of cash on this, so I'd probably sell them for $6 plus $2 shipping/handling/packaging for US Residents, as I'd probably have to buy some padded envelopes (expensive and increases postage weight).

Realize that you can't just hook up a voltage source to these, and that you'll have to make an investment in a good charger. They come pre-charged (at least, both my samples did) and they hold charge for a very long time.

If there's not much interest in this, I'll most likely bail on it. No biggie.
