So far i bought from greatworld and chris_x... their Sanyo are 100% original... didnt gave me any problem unlike Sony.... it sucks hell a lot... especially those AAA ones... use my Sanyo smart charger... it will charge stable for about 10 to 15 times... after that, Sanyo charger wouldnt charge as the LED blink to show error...

Now im testing another 2 pieces of Sanyo 2500Mah AA battery bought from greatworld at RM 10 each. It seems like the packaging is identical with Chris_X. Performance wise not yet tested. Will 2500Mah easily self discharged when it was left keep in the box for a few days after the battery fully charged?

I wonder anyone could help me solve this problem... My Sanyo 2500Mah AA battery bought from Chris_X starting to give me problem. Charge cycle less than 100 times. After charging, left it for about 1 to 2 days... When i use it... It shows only 1 bar of battery level instead of 4 or 3 at least.

Does this battery will quickly self discharge after fully charge?

Oh crap..... What can we do? Does Chris_x aware of this problem?

Does 2300mah battery affected by this?

Now i end with 6 peices of 2500Mah with timebomb.....

Chris_x is not selling fake units... What i found out from greatworld who use to sell Sanyo battery even now.... Even is much cheaper. During 2004 production batch. There is defective on it. I guess i bought mine from Chris_x during 2004 production that has this problem. Current new batch seems to be working find and sanyo has resolve the issue.

BTW, for the tip. Use only Sanyo charger to charge 2500Mah battery as it uses special substance battery.
