I open up my Logitech mouse G305 for battery check, I took out the battery to see the expiry date, next thing i felt liquid through my palm, I thought why would I have water on my palm but i realized that it was from the energizer battery! threw away the battery, washed my hands back to the mouse, there was a small puddle in the battery compartment of the mouse, tried cleaning up and even did a teardown to clean that up, but it was too late, the liquid got to the mouse sensor and it is now total dead. It was total clear like water when it oozed out, during the process towards crystallization, it started to get slight sticky. My mouse was just 3 months old.

Biggest problem I have with Duracell is that they are very prone to leakage. I have damaged so many electronic items by using Duracell. I can no longer leave Duracell batteries in equipment that may sit idle for 6 months or more, and in fact, never use Duracell where I can access an alternative. With Energizer, which I now use almost exclusively, I don't recall ever suffering from battery leakage and subsequent equipment damage.

Recently I had a Chateau (TERRIBLE BRAND!) battery leak liquid.
The battery were in a device for 24 HOURS. Sure, the battery had an expiry date of 12-2019, but still.

I completely stopped using alkaline batteries. I use either the more expensive lithium batteries for stuff that draws low current but must work when I use it (fire alarm / emergency flash light). Or Eneloop chargeable batteries with low self discharge (10%/year), so that they can be in a drawer until I use them.

Yeah, I lost an expensive torch like that.

Energizer battery leaked into torch which meant I could not get the batteries out.

They expanded.

Energizer are shit batteries from what I know of them.

I've seen the liquid a few times. I've tried darn near every brand available in the US. Energizer used to be good, not any more- in fact none are any good any more. I buy the cheap crap where you know 1 in ten cells are DOA or dead soon, swap out the dead ones as needed, then remove them after use if it's going to sit more than a few days unused.

Now anything I need to keep powered gets the 'heavy-duty' stuff, not alkaline, even if it means replacing the cells frequently. If it something which needs to be long-term I take out another mortgage and use lithium primaries (which are usually Energizer brand ones). So far so good.

But my preference for most things where I can use them is now LiIon; one heck of a lot of energy and if not mistreated will last for many years us use. Not a direct-swap for primaries but no leakage and best long-term value where you can use them, especially the 18650 size which has the best 'scale of manufacturing' cost as so many of them, are made. Use only the good ones with a good charger and you'll never want to go back to anything else.

Was there a point to putting MADE IN USA! in the title like that, seems kind of condescending, i've had battery leaks happen from allot of brands over the years, i just don't see the point in that title other than to be a $%@&

I had this happen with the power winder on one of my 35mm cameras. I couldn't figure out why my hand was getting wet, until I removed the battery cover. I was using Rayovac batteries.

"For once it's not Duracells" .. Brilliant!

Having worked in the service trade (TVs & VCRs, HiFi etc.) and since then doing repairs as a hobby you wouldn't believe how many ruined devices (usually remotes but sometimes radios and other portable equipment) I've had to fix, usually with DuraLeak™ cells fitted. Many of these still had charge in them .. maybe exacerbating the issue?

And, yes, I've had a few with the liquid coming out …

I think I've seen the liquid leakage twice: once was in an old 4 D cell camping lantern (probably a sealed compartment) and the second time was when I hooked a 6vdc adapter to a pair of AAs when I was younger.

Is actually not acid inside, that's why they are called, "alkaline batteries". It's the opposite of an acid which is why you use acids to clean up after.

This is also why you should only buy lithium AA and AAA batteries. They have around a 20 year shelf life and never vent electrolytes. They are also waaayyy lighter…

I have. They were heavy duty batteries bought from the dollar store (Dollar Tree). It leaked as a dark brown liquid. NASTY!!! It was difficult to clean up and stained my clothing. It happened more than once. I think they were Sunbeam heavy duty batteries. I will never, ever buy them again.

Once a duracell NiMh 2A Explodet in my Computer Mouse … IT was only a gas burst without flames but IT scares me a Lot !! (Sry 4 Bad English, im from Austria) True Story!
