I am very happy with my Energizer NiMH batteries and compact chargers. The batteries hold a charge very well. My first rechargeable batteries and charger were from PowerEx... the charger is good, but the batteries were the worst. I still have the charger but the batteries are no longer in my bag.
I had Energizer NiMH batteries for year in various electronics around the house, including an older P&S that took AA's. I was constantly disappointed by them. Not one of them holds a change now, and most won't even charge anymore (blinking light on charger indicating faulty battery). I use Sanyo Eneloop batteries exclusively now. They are very reliable, and from what I've found, hold a charge for a very long time in storage between charges.
