Energizer e2 Titanium AAA (4-pack)

Pros: Long life, compatible with electronics requiring more power.
Cons: None. These batteries are more expensive than Duracell alkaline batteries but well worth the money.

I picked these batteries up today because I lost 2 of my 4 required rechargeables. Initially, I bought Duracells($2.29 plus tax) but my camera would not work in the record mode. The message was "Change the batteries." I bought a 4 pack of the Energizer e2 Titanium batteries for $4.29(plus tax) at a grocery store and my camera fired right up. I took about 150 pics today and the batteries are still going strong. I recommend these for any electronics that require more power than a remote control. I am going to try them in my MP3 Player next.
