Hi
I am lost between:

1) 2300 mAH NiMH AAA battery
2) 800 mAH I-C3 NiMH AAA battery

I wanna ask which one of 'em is stronger than the other so that it can give me the maximum playing hours for my MP3 player (Cowon Iaudio 5)

Will appreciate any info coz my aim is 2 buy the strongest NIMH available nowadays and neglecting costs for now.

THANKS
