    Are there any name brand "AA" or "AAA" Lithium ion cells on the market
    that can be RECHARGED?

    Or anyhting that looks roughly like good quality. Please advise source
    for cells and charger.

    All I can find are Chinese ones on eBay.

    It would be a rather strange package for a Li-Ion battery, since the voltage
    would be all wrong for the appliance. Without knowing what any given stupid
    company might do, I'd guess that they don't exist.
    NiMH? NiCD?

    ** And that is all you will find.

    The major brands are not supplying them cos there are too many hazards with
    consumers using them - as they have triple the voltage of other
    rechargeable AA and AAA cells and will catch fire if over charged.

    ** Why change your name every time you post ?

    In recent days you have also been " Bob Morris", " Martin Evans" and "
    Karl Roberts" .

    Damn silly thing to do.

  5. No, Like others posted they are different voltage and require special
    charging considerations.
    Are you looking for shelf life? or capacity?
    In the NiMH lineup, Eneloop for shelf life or any other SANYO battery
    for capacity.

    NEITHER ! :) Lithium
  7. Would you consider Tenergy a name brand? If so, there are some here:

    They are also available without solder tabs, but only with a flat top,
    not with button top:

    The important question is: What properties of the Li-ion batteries is
    it that you are interested in?

    Since you specify physical size, I suspect you want to replace NiCd or
    NiMh cells with Li? In that case, the different voltage would need to
    be considered, but also the different voltage discharge curve. Ni
    batteries have a fairly constant voltage all the way down to empty,
    while Li batteries have a voltage that varies quite a bit between
    fully charged and empty.

    I meant *USE* NiMH or NiCd. LiIon is a non-starter.

    AW brand is the best in the high-end flashlight community. I keep the
    CR123 sized versions in my pocket rockets:

    I'll assume you know what you are doing with them.
