I purchased a box of the Costco (Kirkland) AA batteries a little while (?6 months?) ago. We just opened them recently.....I've now opened the third package and have found that they won't even power my mini mag <img src="/images/graemlins/shocked.gif" alt="" /> (with the LED !) <img src="/images/graemlins/confused.gif" alt="" />:. I will be returning them to the store for replacement.

I should mention to you that this is the FIRST and hopefully only time that I've had a problem with the Kirkland batteries. It will definetly not stop me from buying them. I just wanted to let people know in case they run across the same problem.
