You can buy "name brand" batteries, or you can buy private label batteries. I prefer to save a few dollars and buy private label for certain items and AA batteries are one of them.
I don't buy "Heavy Duty" AA batteries as they aren't nearly as good as alkaline batteries. Some devices won't allow the use of heavy duty batteries unless you want to void your warranties. But alkaline batteries are a safe bet if you buy ones that do the job right... correct voltage, long lasting while being used, and long lasting shelf life.
The Kirkland brand is Costco's brand. I picked up their 48 battery pack for $10.99. That's about $0.23 per battery. Compared to brands like Duracell, that's about half the price. Not bad!
I checked the batteries on a digital multimeter and they read 1.625 Volts each. That's pretty good. AA batteries are rated at 1.5 Volts. Getting a little more out of the battery to start is a good thing.
In the past, I have purchased batteries from Rayovac, which is a name brand. Still, in general, I found that Rayovac tends to be less expensive than Duracell and Energizer as well and they have always held up well too. But these Kirklands are even less expensive and seems to do a good job too. So why not?
Some online reports have also confirmed that the Kirkland AA batteries do a fine job. Click here for one of the reports.

Just don't use the CVS batteries in anything you want to work for a good amount of time. With good brand name batteries my GPS works for 8-12 hours. It crapped out at 4 with CVS. I read a study that showed Kirkland was at the top of the generic batteries tested and the name brands were only slightly better. Just stay away from CVS generic batteries, at that rate it is more expensive to use them.
Interestingly, I have heard the same thing said about Walgreen's Alkaline batteries as well. Others have told me that they don't last too long either.
Thanks for your comment!
