AAA,AA have high incidents of leakage
on January 16, 2018
Posted by: David S
from NYC, NY, United States
I'm a heavy user of AA AAA and 9 Volt batteries.
Until recently I've been a big fan of duracell batteries. They were the best.
There's been a very noticeable degradation in the build quality. The AA and AAA batteries are very susceptible to leakage & destruction of the devices that they are enclosed in. I'm looking into alternative sources of batteries. Duracell has passed it's prime.

Disappointing Performance
on January 15, 2018
Posted by: ShreeTE
from Indianapolis, IN, United States
Duracell hearing aid batteries lasting barely 1 day and performance is unstable. We purchased a 32-pack of Duracell 312 hearing aid batteries on 1/5/2018. The best-by date is March 2021. I opened the package on 1/8/2018, and in 7 days I have gone through 5 batteries already.
My hearing aids are connected to my cell phone through a Bluetooth app which gives me various information including battery strength. These batteries come out of the package at 60%-80% strength. Some batteries are malfunctioning within minutes of insertion.
My audiologist warned me that store-bought batteries are mass produced and sit in warehouses for long periods of time resulting in greatly degredaded performance. He recommended I purchase my batteries through him; admittedly an obvious benefit to the audiologist. The audiologist supplied my first box of batteries [not Duracell brand], and those batteries had a life of approximately 5 days under heavy use.
When I purchased my latest package of Duracell batteries, I was very disappointed at the performance; both in longevity of battery and of various malfunctions, such as my hearing aids shutting off minutes after new battery insertion. In one example, one hearing aid shut off while I was busy and did not immediately replace it. Over an hour later, the hearing aid turned on without intervention.

The Duracell AAA battery 16 pack that I bought does not last 1/4 as long as an energizer of equal value. I use them in my insulin pump and for whatever reason they just don"t last. # on package is 7216868101 date is march 2027.

A 9V Coppertop Duracell battery touted to last 5 years and placed in my smoke alarm, was dead within a year. Supposedly good until 2020, dead in 2017.

Can't open the package or they die
on December 17, 2017
Posted by: Jack54

I am so tired of these batteries that are left in the open package dying before I get the chance to use them. You used to be able to buy a multi pack and have the rest available. Every time I go back to the open package to get batteries to replace ones that have been used up in a device, the ones in the package are dead. This has happened so many times I am furious. The ones I just attempted to use say December 2025 and it is currently Dec 2017. The package says "Guaranteed for 10 years in storage." They are in a dry drawer at room temperature, in their original packaing with the plastic case snapped shut. So I just lost 7 batteries I paid for! this has happened numerous times and I am quite tired of it. The ones in the device last pretty good. But I want to be able to have ones on hand to use!

Duracell batteries NEVER used to leak! Now they are giving their nearest competitor a challenge for the worst batteries ever. Duracell,l if you are monitoring you need to figure out what the problem is. Your reputation is ruined!

Bad quality
on December 7, 2017
Posted by: Bill Mac
from Commerce Charter Township, MI, United States
I used to always buy Duracell batteries, but in the last 3-4 years I have lost 3 expensive flash lights and 4 or 5 cheap flash lights and a awesome remote control for a stereo receiver that could control multiple equipment and is no longer available. They just leak and corrode. I don't usually leave reviews but I am disappointed in the quality of late.
