My BJ's carries a 48 pack of Lextron AA for $9.99 vs. a 36 pack of
Energizers for $13.46.

I looked at Consumer Reports and they tested 14 brands of Alkaline
batteries. They included name brands (Panasonic, Rayovac, Energizer,
etc.) and store brands (CVS, Rite Aid, Kirkland, etc.) Unfortunately,
the Lextron's are not on the list.

CR gave 13 out 14 of them "very good" ratings for use in toys, cd
players etc. One got a "good." All 14 got a "fair" rating for use in
digital cameras.

However, they state that they are listed in order of performance, so
there must be some differences, although they don't define them. They
also don't separate performance in camera from performance in a cd
player - it's the same list - so I'm a little leery to use the
performance ranking to make any decisions. The video says they top
rated the Kirkland's based on the price - 21¢ per battery.

So, can I assume that all AA batteries are so close to each other in
performance that I should shop on price alone? That would make the
Lextron's (21¢) as good a deal as the Kirklands.
