    Anyone have any pointers to decent price & quality AA NiMHs batts?

    Previously I've bought Jaycar's "Powertech" 2000mAH for $4.25 which seem to
    be quite decent, but Futurlec flog Sanyo 2100mAH for $3.16 and I'm under the
    impression that Sanyo batts are pretty good. However I notice that the US
    Futurlec site has Sanyo 2500mAH for US$2.25 - I assume these would be
    available in Australia somewhere as well?

    Any suggestions?

    I personally am happy with the Jaycar Powertech batteries. I have the
    2400mAh "AA" size, I get around 600 photos with LCD on my camera (S2is) no
    flash.

    I was a bit worried at first that I would not get the performance out of
    them but am now quite happy with them.

    I didn't notice the 2400 ones on their web site, maybe because they've
    changed colour. At $5 a pop they seem a bit steep, but if they deliver the
    goods they might be worth it.

    Thanks - I'll have to rifle through the collection of updates - I wish
    they'd sort out some kind of online system.

    I bought 12 Powertech 2.3AH cells. My Lightning Pack 4000N
    intelligent charger would often shut off prematurely in a 'fault'
    state when charging them.
    They powered two Olympus digital cameras pretty well when charged
    by a cheap PoweBase charger, but Sony digital cameras are very
    particular about the internal impedance of their power source and
    would shut off after only a few minutes of use.
    I eventually replaced them with Energizer 2.5AH cells, which the
    4000N charger and the Sony cameras are happy with.

    You, me and about 2,000 others are waiting for them to get their act
    together. If Rockby Electronics can do it, so can WES!
     
  8. Sanyo are traditionally regarded as the best rechargeable cells.

    Whether that is actually true today is another story.

    Exactly. That reputation comes from the days of NiCd's.

    I was using Sanyo 2.1AH NiMH cells in two digital cameras,
    alternating them with cheap 2AH PowerBase ones. I was surprised that
    although I bought the Sanyos after the PowerBase cells, they lost
    capacity to the point of being pretty useless while the PowerBase ones
    were still working OK. Hmmm....

    I emailed WES and they are selling their 2500mAH AAs in a 2-pack for $5.50 -
    ie. $2.75 each, which is pretty much the cheapest I've found so far. I'd
    really like to get one or two to start with, and do some charge/discharge
    cycles to see what their capacity is like (I've got a fancy charger that
    tells you how many herbs it puts in or takes out) But I really need the
    things for a flash that just munches through the alkalines.

    Thanks for the info. NiMH cells are much better suited to very high
    load currents than alkalines.
    I've seen icecreams which cost more than each of those cells. You
    don't have much to lose, so give them a try. :)
