Well, the ugly truth about Alkalines is that Eveready and Energizer are both the same batteries from the same company, and Spectum makes Ray-o-vacs and Enercell. That accounts for 85% of the market. Apparently there are a limited number of North American alkaline battery manufacturers, which Comsumer Reports have reported all produce essentially the same product. Their advice, shop cheap.

For IMRs I personally like these On The Way batteries. They have all the things you should look for in IMRs, high capacity, circuit protection, reasonable price.
