Not very good
I used to think about Sanyo as a top performer in rechargeable batteries.
These cells are "nothing to write home about".
They do work, but I am not sure they hold 900mAh - at least Sanyo 800 mAh Eneloop outperformed them almost 1.5 times in my MP3 player.
Don't hold full chanrge, discharge quickly
Batteries don't seem to hold a full charge. Batteries discharge rather quickly. Have used similar AAA rechargeable batteries in the past with better results. Will try a different brand next time.
