thank guys again.
eneloop was really disappointment. I got them from Challengers.. Now, I was trying GP rechargeable now. the 1st two rounds chargings did not bring much improvement (slightly better than eneloop). And the battery indicator went to red quite fast. I had to turned it off for a moment in order to get more power..(at least, it could be yellow when I turned it on.)
I did not use live view and most of the time, no flash
Get Maha PowerEx NiMHs or the imedions (similar to Eneloops) and the Maha MH-C401FS charger. They can charge any brand batteries and are individual charging too.
