Question about NIMH AA battery chargers

    After much debate, I finally decided which camera to buy (Canon PowerShot
    A95) and am quite happy with it so far, but I'm now a little daunted by the
    variety of NIMH AA battery chargers available. Ideally, it would be nice to
    have something that charges reasonably quickly (a few hours rather than
    overnight), that will shut off on its own and not overcharge batteries, and
    that isn't horribly expensive. Even better if it's something easy to find
    in a store or online. Any suggestions?

    There are a million opinions. I've had great luck (not that luck should
    have anything to do with it...) with a MAHA MH-C204F. Decent price,
    there's an online dealer, came with a set of MAHA NiMH.

  3. Of the four chargers I've used, that is the one that I can't recommend.
    It was designed for older, lower capacity batteries. It's slow and it
    doesn't reliably detect a full charge on higher capacity batteries.

    I've had very good results with the Rayovac 1 hour NiMH charger. It's
    fast and it doesn't heat up the cells much. It's one shortcoming is
    that it will sometimes cook new and unused batteries. New cells go into
    the Maha MH-C204F, which doesn't have the current to do much damage if
    it doesn't shut off, or I take them out of the Rayovac when they get

  4. Avoid the fast chargers, they beat the batteries up too much.

    Or get one that's switchable. I like the Mhaha Powerex C401FS, which
    does slow or fast charge, has 4 independent charging circuits, and
    "FLEX negative pulse charging". Or I see they have a new C204W they
    think well of.

  5. Easy to find in almost any city or town, charges in a half hour or less,
    switches to trickle when done, comes with four batteries, cheap:

  8. I put together a small web site with chargers,

    Look at the Panasonic BQ830 (Costco) and the Maha C401FS. The Panasonic
    seems to have some issues with non-Panasonic batteries. It comes with
    eight 2300mAH AA cells (and 2 AAA cells of 780mAH (I think)), and Costco
    sells additional Panasonic cells pretty cheaply. But the Maha is
    probably the best choice, albeit more expensive.

    Avoid chargers that charge in pairs.

    Avoid very high rate chargers with no option for lower rate charging.

    Avoid the Ray-O-Vac charger.

    I have both the Panasonic charger you noted, and also an Eveready charger
    and batteries that I picked up at Wal-Mart.

    I notice that the Eveready charger takes 7 hours to recharge, regardless of
    whether the batteries were fully exhausted at the beginning of the charge
    cycle. It appears the Eveready charger goes through a discharge cycle, and
    then fully charges the batteries.

    The Panasonic charger, by comparison, just brings the batteries back up to
    full. Depending on whether they were fully discharged, I have had it bring
    my batteries up to a full charge in anywhere from 15 minutes to 3 hours.

    As I tend to recharge my batteries at the end of a shooting session,
    regardless of whether or not they are nearly dead, I prefer the Panasonic.

    I've got a Rayovac 1 hr charger that I got at Target for around $20. It
    charges the 4 cells individually (also charges AAA and 9v, which were
    important for me). I've been using it for over a year and it seems to work
    just fine.

    I know some people advocate slower charging of cells, but they just don't
    cost so much that I'm going to worry about it.

    I'm right there with you Bob. The Maha chargers are excellent units,
    but a four-pack of NiMH cells is pretty darn cheap at this point and
    in the 2 years I've had my Ray-o-vac 1hr chargers (I have two) I have
    only had one battery go bad on me (stopped taking a charge after about
    3 charges).
