AAA Battery Leaks
Best Uses

On Items That Are Used Of
I left these batteries in a voice recorder, not used too often. When I went to use the unit I noticed that the recorder did not work, figured the batteries went dead. Opening the battery compartment I was greeted with battery leakage all over the interior of the recorder. The batteries may be less expensive but considering the leaking issue I have had with Kirkland batteries I will go back to Duracell.

I LOVE COSTCO, AND NORMALLY WOULD NEVER SAY ANYTHING NEGATIVE; but I think this is an issue that needs to be looked into by CR and COSTCO. We have noticed for several years more than 5--That AA Kirkland batteries tend to corrode the longer they are in a product. It has the potential to damage the electronic deice, if nothing else to make it difficult to clean and or rusts the battery compartment and contacts... We have seen it occasion in all Kirklands, D, C, AAA, and 9V, but mainly it is the AA perhaps, because that is what we use the most of... and it is usually in the items we DO NOT use as often, less frequently, as say a Digital Camera or Automatic Air Freshner. Especially if the item sits in a drawer or on a shelf unused for weeks or months at a time unused or only occasionally used. And of definitely it seems the more moisture the item is exposed to the more likely it is to occur. This has happened in both Southern California where I lived for 25 years and in North Carolina where I am originally from/family lives and I am currently living again--temp hopefully Miss the OC and the better weather and my 4 Costco's in 5 within 5 miles of me... instead of having to drive 50 miles here in NC to the nearest one. The price is unbeatable, and the POWER supply is great and consistent immediately, but in a HIGH useage item such as a digital camera... the life of the Kirkland batteries is drastically cut short when using with a digital camera... Also there seems to be far less chance of corrosion if the power is used steady and or quickly upon putting the batter in service in stead of leaving the batteries in an item waiting for use.... like a flashlight, or a bug sprayer, or some other thing that doesn't get used as often... even an older model phone that required batteries to maintain the memory for speed dial and such... it would eventually start to corrode before I would remember to check to see if it was time to replace them. So if the Issue could be resolved... a better seal to prevent leakage from power bursts, or the leakage of charge due to not being used... The KIRKLAND battery would be a definite RIVAL TO #1 Duracell Ultra if for no other reason because of the price... You could afford to use Kirklands for Digitial Camera even if you did only get one Event of film shooting per Kirkland at 1/5 the cost per battery. By the Way... I I can no longer buy Duracell Ultra at Costco only quantum and coopertop. in Fact Sams has also switched from Everyready/energier to Duracell--Except for the Energier Lithium Ultimate--which Sams Club still sells)
