Duracell 41501 MN1500B4 AA Battery (Pack of 20)

I have at least 3 dozen each of AA and AAA batteries, all with at least 5 years left before the expiration date printed on the cells. I throw some out every month for premature failure due to leaking, some in storage and some installed in devices where the leaking induces corrosion on device battery terminals. I am about to throw them all out in favor of another brand.

I bought the AAA coppertop batteries because the container indicated they were guaranteed for 10 years. For the extra cost charged for these batteries vs generic brands I expected good quality and durability. These batteries just don't last. I won't buy them again
