I got konnoc 2500mah nimh AAs, 8 of them. The charger that come with it, no good.
The problem comes when battery still got power, you recharge it. The charger did not recharge the AAs fully. I had a case when the charger indicated full charge, and I took out for an outing. Shot the first one, okay. Second shot, the output down and by the third shot, no power. I took the batteries on a full charge with the Maha - shoots beautifully. What does this tell me? So I want to verify. So, I charge the AAs to full power in the Konnoc, put into my Maha charger, the AAs still need to charge for quite a while before it turn green and fully charged.
From my experience, the konnoc batteries are quite good and economical, but stay away from their charger. Currently, I use konnoc 2500 with Maha Powerex MH-C401FS 100 Minute Cool Charger. The charger does a decent job of ensure my batteries are fully charged!

I heard from some sources that the Sanyo 2500mah are not consistent performers, so I am staying away from them until proven otherwise. Heard powerex 2500 is good, but I will wait until my konnoc die before procuring new batteries.
