Duracell Quantum Alkaline AAA Batteries, 16 Count

I do not normally write online reviews but decided to in this case to warn people of the almost 100 percent probability that the Duracell AA or AAA will leak. In browsing thru the existing reviews it is apparent that I am not the only one to have issues with these batteries. The C and D batteries do not seem to have the same problem.

Duracell used to guarantee to repair or replace a device damaged by a defective battery, but no more. They will evaluate the consumer complaint, and then make their decision. In other words, no definitive guarantee is provided. I would be wary of these batteries. I have had new batteries leak while still in the package. I have had new batteries read low voltage right out of the package.

Just had a maglite flashlight destroyed from leaking Copper Top battery. Just using in non extreme environment. Very diapointing. Third occurane of an issue in lat 8 years. It may be time to try a new brand. I used to excusively use Duracell batteries but not sure this is smart to do anymore.

I've used Duracell for years. Last year the one in my keyless garage door opener died after 8 years of service. So I purchased and installed a 9V Duracell Duralock in September of 2012. Today, it died and I was locked out after dropping off my car for repair. Later, on checking with a voltmeter, the battery read near zero. I checked the last one from the same package and it read well over 9V. I put it in and the opener now works. But I wonder for how long. And I have a couple in smoke detectors. A single failure (never before with Duracell)? Or a pattern. Other reviews make it look like a pattern. I will reconsider my commitment to Duracell.

I am very disgusted with the old and the new Duralock batteries and will never buy again!!! On the coldest morning we woke up to no heat, why? because our Duracell AA battery leaked inside our digital thermostat, therefore we had no heat all night. Temp in the house was 50-degrees burr. Thank goodness my husband was able to clean the acid off and we could get the furnace running. I hope we didn't burn up the furnace motor. This is not the first time this has happen with leaking. I had to throw away many items because they couldn't be cleaned. Duracell used to be the best until about 2 years ago. I would not recommend.
