    I am looking for information on the use of rechargeable CR123A (CR123
    etc) size batteries in film cameras. Because I use an Olympus IS-3, the
    ZLR style of the camera requires "power zoom" and drains lithium CR123's
    with frequent use. Normal CR123 size batteries supply 3v each but the
    ones seen on ebay supply 3.6v each. I am wondering if such a voltage
    difference will overload the Oly IS-3.

    Another online source sells rechargeable "R123A" batteries rated at 3v
    but are about 2x the price for a set+charger. Anyone have any
    recommendations on sources for inexpensive CR123's or advice on
    rechargeable CR123's? Thanks.

    It might be a problem. Probably it would be wise to ask Olympus.
    LiOn cells often produce more than 3V. Regular CR123 batteries cost
    only about $1.50 now, so maybe you should just bite the bullet...
    Doesn't seem like a promising technology. CR123 batteries are physically
    too small to contain two high-capacity NiMH cells, which would be required
    to produce almost 3V (actually only 2.5V). LiON cells produce 3.6V so I'm
    not sure that the specifications of the "R123A" are correct. It's doubtful
    that it's any different from the Ebay battery you mentioned above.

    After some more looking around, it seems there are a number of people
    who've had success with lithium cells from surefire.com. A box of 12
    cells cost $15 + $5 shipping. The brand name photo lithium cells at
    the local stores still go for around $5+ a piece, I am not sure where
    you would get $1.50 photo cells locally.

    I'll test the surefire.com lithium batteries when they arrive, hopefully
    it will be a while before i need more.
