OP must be pretty young 😂, we old fucks have seen this happen 100 times

Get the batteries out and wipe the electronics with a soft towel soaked with a little vinegar to neutralize the corrosion. Then a damp towel with just water to get the vinegar up. Let it fully dry before putting in new batteries. This happens to batteries that have sat unused for a long time installed. It can also happen if at the end of charge, you pull the batteries out, and put them back in to squeeze a little more use out of the batteries. Do it too many times and there is a leak risk. Cheaper batteries do it more often but the top brands will occasionally leak as well.

Old batteries get spicy.

Yes? It was extremely common as a child because all our toys were battery powered (but not included)

Many times. When buying old battery-powered electronics, there's like a 50% chance that there's a leaked battery in there. Make sure to wash your hands if you touched that.

Oh my sweet summer child... Just don't taste it.

The forbidden frosted sugar.

It has happened enough times to me being really aware of removing batteries of any device that does not see constant use

Yes.

Basically if you leave Alkaline batteries in the device for a long time (years) without using them they will loose all charge and there is a chance of them leaking.

Leakage is significantly more common with the Zinc-Carbon batteries (the tech in use for most batteries in that format before Alkaline) though those leak something that forms blueish crystals.

No. I had an OG gameboy and my parents wouldn’t buy more batteries so every remote in the house had its batteries liberated for the glory of super Mario land 2 6 golden coins. They didn’t get the safety and security of rotting in a tv remote. They were fed to the Tetris vampire.

Yes, this is definitely worse 'than average' but have seen this before.

DO NOT TOUCH WITH BARE HANDS, EXTREMELY TOXIC.

This was very common pre 2010s.

This was so incredibly common before rechargeable batteries. Alkaline batteries may have had the best life but the worst death.

how old are you?

This happens when alkaline batteried are completely empty.

No, thankfully, I'm not a battery. But I've seen it plenty.

Ah, the forbidden salt. Yes, I remember it fondly from when I was but a young boy, playing the GameBoy Color.

So often that I have banned alkalines from the house, everything gets NiMH rechargeables.

Thats my, favorite sweet&sour candy

I lost my favorite mouse this way :(

Make sure to take ya batteries out if you're putting electronics in long storage!

As a millennial: all the time

What I did only experience once, was a leaking alkaline battery while in use

Mouse stopped working. Opened it up, only to be greeted with freshly squeezed battery juice dripping out of the battery

Mouse worked fine with new batteries, so no short in there.

Was even high end Duracell

Yes that's what they're called alkaleaks.

the fate of old batteries. if you're storing electronics for a long time, take the batteries out.

You know, at first glance these looked like 2 dollar bills rolled up to do coke with and these were after a couple of hours of use and the coke was getting gummed up around the snorting side. My first thought was "Yeah, I'm familiar with that."

Sure, dust out with a paintbrush...wipe down with some alcohol. If the contacts are corroded either file or use a dot of lemon juice and a toothbrush to remove and then either spray with contact cleaner or wipe again with alcohol.

3 or 4 times at least

Several times in my own electronics and many times in secondhand items. The potassium hydroxide electrolyte never quite evaporates and seeps under the crevices, requiring a full disassembly to prevent further corrosion.

Worst offenders are the pesky little alkaline button cells. Every alkaline cell inevitably evolves hydrogen gas as the electrochemical reaction proceeds and in those tiny canisters, the gas very quickly has nowhere to go but out along with the cell's guts. The secret is to get the silver oxide versions, same voltage, a bit pricier, but far less leakage.

I guess the silver lining to the declining popularity of AA and AAA powered devices is that I can finally afford to use only Ni-MH or primary lithium cells in all of my devices. Those chemistries are mostly immune to leaking.

Do not leave batteries inside things your not gonna be using for a long time. And if you don't want this to happen buy NiMH batteries

I've never seen your remote before, so no.

Battery orgasm?

Happened in my Wii remotes all the time when I was kid, only ever lost one to battery corrosion though, and that was about a decade later

That's why I put non rechargeable batteries out, before putting them away for long time without usage. This won't happen if you are constantly using the remote and batteries, and it won't happen with rechargeables. Edit: Read the replies to this comment. I was wrong.

Goddamn you had a blowout

I should go pull the batteries out of my game boy color because I'd rather not experience this again.

few times, but it luckily never broke the devices it happened it

Define experience

That's how cocaine is made

Every '90s kid remembers this!

Yeah, get accu cells. More environmentally friendly and they break without running out.

yeah it tastes like donut creme

Don’t lick it.

It’s sour with a mix of pain if you’re wondering, and now that you know this you do not need to lick it.

If the words on the batteries read the same way, it will cause acidic fuzz like this.

* They may have been correctly inserted, and then left a long time, which can also cause fuzz.

Yeap as a reseller happens quite a bit and I found battery that expirebbsck in the 90s in a portable speaker
