    BTW, AhV, I've PMed you previously, as your mailbox rejected my emails.

    no worries ..you are already in my first list, which i ve submitted to SANYO If I am not wrong, most rechargeable batts can last > 500 cycles. Maybe some of the IT guys here can clarify further...80 cycles sound too short for such investments. Do save your $$$ for the new SANYO batts - after we solve the 2500s' issue ....

    That is bad. I had 5 sets of 4ea. All of them went berserk with rapid discharge just overnight! Previously, they'd last a week, which I consider reasonable. Then overnight the whole lot went to flat-after-five-hours. Because of that I put a hold on the use of my remaining 2 sets (which also discharge after a day).

    I'd thrown those 20pcs away in Aug.

    All the same, for you AhV.

    I've taken to keeping 2 sets Fujifilm2300, 2 sets Konnoc2500. The 2 sets of Sanyos are spares... just in case.

    As for our neighbouring CS members, I will ask them what you can do if you had bought your batts in your country e.g. M'sia I am sure you will have a solution too. There will probably be another 'AhV" in your country
    From Malaysia, I mail ordered my 2500mAH batteries from East Gear, then how?

    I have 8 pieces of Sanyo 2500 and they seem to be exhibiting the same problems.
    Drain within the week. Batch 04-09-S1.

    My 2300, 2100 and even the 1600 Sanyo battries are still ok.
    Yes even real old 1600 still can hold its charge.



    My Batteries.


    I am using the Sanyo Quick Charger with refresh and also the MAHA charger on all my batteries.



    Good job AvH. Appreciate what you are doing for us

    AhV, first of all, thank you for your effort of helping us photographers.

    I am from Malaysia, and I have bought nearly a hundred packs (4 blisters and 2 blisters pack) of Sanyo 2500mAh batteries for my PhotoMalaysia members in Malaysia. I believe some of them have the faulty batteries, but they are now all over in Malaysia. So, what can Sanyo Singapore do? Can you help me to check with them? I bought the Sanyo 2500mAh from Singapore with the trust that those in Singapore should be the better original batch...

    I got the same problem when my sanyo batteries exhibit low charge on the camera batt indicator, sent an email to eastgear and got this reply

    "Hello

    NiMH rechargeable batteries are typically rated at 1.2v whereas
    alkaline and lithium are rated at 1.5v. Thus you have a total voltage of 7.2v
    versus 9v when using alkaline or lithium. While rechargeable batteries
    start at a lower voltage, they are able to maintain this voltage for
    longer than alkalines which have a linear discharge curve.

    The lower voltage also means the battery indicator will show the
    batteries are at partial instead of full power. One way to test would be to
    compare the number of shots you can take with alkaline versus NiMH
    rechargeables. The NiMH should be able to take more despite being at partial
    power.

    Using AA batteries in the BG-E3 is usually meant only as an emergency
    measure.

    Regards
    (name)"

    Thks! will PM u my batch number tonight or tomorrow evening

    One qn, does this behaviour start from day 1?

    Update: hmm after reading the posts more carefully, looks like the behaviour can come in halfway.

    Actually, the older green Sanyos were really good. I've read that the 1800mAh batts outperformed many 2000mAh batts.

    All,

    I have 12x Sanyo 2500Mah. Initially I though the fast drainage of itself only happen to me. Seem it is the quality issue. My one is 05-03-AC batch. Will become flat after less than one week without usage.
    Question now, Sanyo commit replacement?

    Wonder

    Default do you have 2500 "SUPER LAO SAI" batts ??

    ok...everybody listen up..SANYO just contacted me again today.

    They need more extremely 'BAD' 2500s batteries .... do a test on yours again..if yours "LAO SAI" at F1 speed and is already on my list, drop me an email to volunteer your samples. I will need to collect your batts from you. These batts will be sent to Japan for stringent testings.

    The list is growing daily but I will close the request for info at month-end for final consolidation of my list. So, HURRY if you are still not on my list. I will send acknowledgement to those on my list at month-end.


    Please bear with me as I will only provide update once I have updated additional members.

    Cheers !

    AhV, possible to meet up with u and pass you my whole collection?
    mine's championship material.

    3sets of 2500 and 2sets of 2100 only. threw away many more before this latest purchase.

    good move by Sanyo boys to stop the rot.
    but i'll be battery-less for quite a while so meanwhile, i'll just buy other brands.


    cheers! thanks for ur help!!

    Hi guys, Joined this forums just for this issue cos I also happen to purchased 5 sets (of 4) AAs! that's 20 Batts affected

    My batch aren't that badly affected yet cos I just bought them a few months back via lelong.com.my from some store called WinCom in Penang. But can feel that it's worse than even my 2100s... something is wrong!
