    I just bought a Uniross fast charger and 2100mAhr Ni-MH AA
    rechargeable batteries for my new digital camera. I bought two sets of
    batteries so I have one spare. I'd like to keep the spare set in the
    charger so they're all in one place, but someone told me that if you
    leave newly charged batteries in the charger, even with it switched
    off, the batteries will discharge faster than if you keep them out of
    the charger. I'm having difficulty finding a storage box locally to
    keep the spare set in. I don't want to carry the spare set in the
    camera case due to the extra weight so keeping them in the charger
    seems the best option. Any suggestions? I always recharge batteries
    after they go flat and store them that way so they're ready for use.

    Thanks,

    Ken
     
  2. To hold the charge longer, store the charged batteries in the fridge.

    Hope this helps.

    Emmmmm... yes, I could, but the charger has a car lighter socket
    adapter and I was hoping to keep the batteries with me when I'm out
    travelling. I was looking for an answer more along the lines of
    either "No problem storing them in the charger" or "Better to get a
    battery case from <supplier name, preferrably in the UK>".

    Thanks for the suggestion anyway, I've some space in the veggy drawer.
    Or would they be better in the freezer compartment?!

    the 3448-40 holds 4 sets of 4 AA batteries, I keep 3 sets of Nimh and one
    set of info-lithium with me at all times. Goggled to get the link and came
    up with some UK distros, I got mine at Bass Pro Shop here in the Colonies
    <g> the lid is a slight press fit to close which helps keep the batteries
    from sliding around, HTH

    Right next to my car battery?

    do an excellent rubberised case to hold 8 AA batteries for about £3
     
  9. I keep mine in the fridge. IMO the freezer might crystallize something
    that shouldn't be.

    I don't know about that. There might be problems with condensation
    when removed from the fridge, not to mention moisture in the fridge.

    As for the charger - if you leave batteries in without power, there's
    going to be some discharge through the circuit. You already have
    the charger, so I guess a smart charger with trickle charge is not
    an option.

    Ken,
    Depending on the charger, there might be some drain on batteries
    left in it with the charger unplugged. I have a nice wallet that holds
    two spare sets of batteries and a couple of extra cards. Of course you
    KNOW not to drop spare (or used) batteries into your pants pocket. I
    can PERSONALLY testify that this is not a good plan.

    NOT in the freezer. Place in a plastic bag, force out all the air, and
    store in the refrigerator part at 40 Degrees F.

    I don't know what your charger looks like but you might consider getting a
    piece of thin plastic (open up a sandwich bag?) that is just the right
    size so that when you place it over the housing in the charger into which
    you put your batteries and press the batteries back into their position in
    the charger, the plastic sinks into the housing with the batteries with
    just enough left over at the ends so that the excess covers the terminals
    of the batteries when they are in the housing.

    If this is possible, that would seem to be the simplest solution.

    To extract the batteries, you just tug on the excess piece of plastic
    sticking out of the housing.

  14. Leave NiCd and NiMH batteries at room temperature and let them
    self-discharge. Leave lead-acids on a constant float-charge.
    Primary batteries are best stored refrigerated. THe chemistry of
    these things differs greatly. Use them as their manufacturers
    suggest, and whey will do well.

    Now that everyone else on the planet has been consulted, how about the
    people who designed and built the thing. Note the "FAQ" indicating
    you're not the first to ask by far.

    http://www.uniross-batteries.com/UK/info/FAQ/0400#11

    At least the battery university thing was informative.
     
  16. That is the sort of trick I use to haul my digital cameras around
    when travelling. Using _very_ thin, and appropriately cut and
    trimmed pieces of plastic, I set one over one or more battery
    contacts before closing the compartment and putting the camera
    into its carrying case. I've found my camera(s) "ON" too many times
    when pulled from the carrying case to do otherwise. Sure, there is
    an "AUTO SHUTDOWN", but I do not need the aggravation. At airports --
    when going through the Illusion Of Security -- it is a simple
    matter to open the battery cover and blow out the plastic to prove
    that it'll power up properly. (But, I've never been asked except for
    once.)

    When you cut up these plastic pieces, cut up LOTS of them and carry
    them with you in a small zip-lock bag.

    Cool dry place, upright (+ve terminal up) so the vents operate
    correctly. Somebody (Al Jacobs?) suggested boring .410 holes in a piece
    of wood to hold thems ecurely upright.

    In a camera bag, strap 4 batteries together with a an elastic band and
    find a pocket that will ensure the batteries are +ve terminal up as much
    as possible.

    I have never heard of this. Does it really make a big difference which
    direction the batteries are oriented? Is this just for rechargeables?

    If this were a big factor, I would think that manufacturers of
    battery-operated equipment (such as cameras) would have the battery
    housings oriented so the batteries are ALL pointing up, rather than
    alternating up and down as most do.

    I have read "keep upside storage" this too .. the argument given is because
    of the overprssure vents .. but I sustain yr argument too ie the up/down
    orientation in equipment so I have no idea it the initial statement makes
    any sense after all.

    Thousands if not millions of rechargeable batteries are in use. My
    completely uneducated guess is that the writer of the article you quote plus
    a couple of his close friends and confidants carefully store their
    rechargeables upright. The rest of us (thousands if not millions), just
    throw in them in their pockets, camera bags, whatever, so I wouldn't lose
    any sleep over it.
