Flashlight Batteries that leak/corrode?

[Billrog]

Always had leaking battery's yrs. ago 90 % are Duracell now and have not had one leak even in the flash light that sits in the backhoe yr. round and they also last better just replaced the 2 in a smart level over 20 yrs. old.

I have lost several aluminum flashlights because of this. Hasn't happened to my plastic ones, but I have lost other electronic devices to corroded batteries.

We have numerous crash carts around the Hospital... all have 3 a cell maglite in holders mounted to the carts.

Some of the carts date to 1995...

The last 3 years I've had to trash several Maglights because the batteries became corroded in place...

I've noticed the same in my AAA and AA personal Maglites too.

Last night a weather station I gave Mom two years ago for Christmas stopped working... opened it up the battery compartment was full of corrosion... I live in a mild climate where it does not freeze nor is it hot enough to have A/C

Mag manuals used to mention using vaseline every so often on the O rings. I try and "re-grease" my maglites at least once/year, seems to help. Lost one AAA mag years ago before I started greasing, have about 3 on the go now, so far so good.

On more open style battery compartments, maybe try slathering on something like Permatex's Dielectric grease ?

Can't say I've seen any Duracells leaking, but only have bought a few in the last years. Have used plenty of Kirkland (Costco housebrand) AAs the last few years - no issues there, and those are USA made too.

There are different types of battery dry cells.
Alkaline, lead acid, zink (something) mercury, nickle cadmium and lithium just to name a few.
Some are just plain more corrosive than others with. I think, lead acid being worst.

With the advent of all the dollar stores there has been an influx of hoards of chicom cheap batteries on the market.
A dry cell works due to chemical reaction whereby some solution (usually an acid) eats a metal and produces electrify.

I've had a few rechargeables in solar landscape lights leak and mess them up.

Currently fighting with this keyboard. There's more batteries in that hole, got one out as you can see, with a wood screw. I don't remember how many more batteries are in there, will consider myself lucky if I can get them out.

Clever using a self tapping screw to pry out the battery.

I haven't had much of a problem since the Raovac and Everyready days. If it doesn't say Duracell I don't buy it. That equipment that comes with other cheeeeep brands gets a fresh start with Duracell PDQ.

I have had many leaking Duracell batteries in the last few years. Also had a couple of 9 volt that were completely dead in the pack that had good till 2019 on them. One had visible corrosion on the bottom and the other one was just dead. I don't think any of the batteries are corrosion proof. I have had button batteries, AA, AAA, C, D & 9 volt lead. I don't buy the cheapo brands, usually Duracell and occasionally Eveready. The cheap Chicom ones mostly don't produce the stated voltage. I bought some one time and tried them in a camera, instantly it said low battery. I finally used them up in my AA flashlight.
I have some Duracell in the computer keyboard that I am using right now that have been in there for 2+ years and still work fine. The mouse burns thru them pretty fast though. The only thing I use lithium on is my laser site on my 9mm handgun, I want it to function perfectly when needed.
