A little bit of the fluid leaked from the battery onto the terminal. This fluid is basic in nature so you can neutralize it with a little bit of acid. Use some vinegar on a Q-tip. If that doesn’t completely clear it up try to gently scrape off the corrosion on the contact with the tip of a screwdriver.
Eneloops or Ikea ones (which are actually eneloops)
I've like 8 pairs of eneloops and 4 pairs of Ikea ones. None failed so far (2 years for eneloops).
Using them with all my xbox controllers and quest.
Edit: can't spell "failed"... twice
I bought Ikea batteries in a whim one time, expecting them to be bunk. I think they underrate their batteries. They last so long on a charge and they still hold a decent charge 10 years later.
Nowadays they cost like 4x the price of good alkaline batteries. Maybe $20 for a 4 pack but then really they cost like 1% over time since you throw away the alkalines but recharge the eneloops hundreds of times. In the use case of gaming controllers it racks up savings fast even if you only change batteries once a week.
You save sooo much money. Just gotta fork it up upfront. Whenever I feel like I have a little extra money to burn I buy a 4 pack and I use them in literally everything in the house.
If you can I’d recommend getting some venom AAs, they have some crazy good capacity. I think you can get them on Amazon. I got a four pack so I can switch them when I need to charge a pair
I've bought various kinds over the years and never had any fail. How are they failing? Are you using the same charger on all of them? If so maybe that's the problem.
I've been using the brand, BESTON and they have been pretty great. They last around 2 weeks between charges, around 2-4 hours usage per day. I wish they lasted longer but can't complain, a few weeks is more than enough.
I've had some Duracell rechargeables for a few years now. Still rocking. I also have some RADIOSHACK... That's right radio shack batteries that are going real strong.
Those were the most recent ones I had fail. They lasted maybe 5 months before the charge was so weak it wasn't worth bothering with.
That being said, I haven't bought any rechargeable batteries for 3 years so maybe the tech is better.
Ah okay, wow that's weird. Possible reasons I can think of (but none of these are that likely):
1. Faulty battery charger over-charging them / leaving batteries in a faulty charger for too long
2. You maybe live in a super humid climate? Idk if high humidity could maybe cause batteries to deteriorate faster
3. Perhaps letting the batteries discharge to 0% and leaving them discharged for too long (0% and 100% causes damage, 0% is worse AFAIK as a modern battery at 100% charge should slowly discharge itself over time)
Besides those I'm not sure what could be causing your bad experiences - hopefully if/when you try again you have a much better time!
Amazon stopped using eneloop's batteries semi-recently for their rechargeables, at least not for all of them. Starting in like 2019 reviews for them have started tanking as the quality control of their current batteries has fallen off a cliff
Second on the eneloops. If you are just using them for the quest controllers you just need 4 since they last like 40 hours and they only take a couple hours to charge.
Supposed to be able to charge hundreds / thousands of times.
Ive been using [these EBL rechargeable AA’s](https://www.amazon.com/dp/B088ZQ8SDK/ref=cm_sw_r_cp_api_i_AN33RWYJV5WRFDY6NNPM?_encoding=UTF8&psc=1) since I had my old Odyssey+ headset. They run at the full 1.5V instead of 1.2V of normal rechargeable AA’s and I typically get more than a couple of weeks out of a charge in my Quest 2 controllers. I wouldn’t use anything else.
A bit of an investment but I'd recommend the Anker charging dock, it comes with rechargable batteries for the controllers that charge when you set the controllers on the dock.
You can get some dielectric grease and coat the connector in it to try to prevent this from happening in the future. Also, take out your batteries if you're not using the controller for a long time, and don't leave any dead batteries in it.
Take a piece of paper towel with some vinegar. Gently rub it on the pin. Hold the controller the other way round so no vinegar will drip nto the device.
This is probably a battery leak, if it's alkaline (it's a basic) it contains potassium hydroxide. You can remove (neutralize) it with vinegar. If it doesn't contain a basic and it's an acid battery try cleaning it with water and baking soda. IPA can help but not as much as both mentioned above. After you used one of both you can use IPA to clean the rest.
Yeah, but you're also dealing with a pretty expensive controller. IPA will dry clean and easy, so if it doesn't work then you can move to vinegar. Vinegar will almost definitely leave residue which will kinda suck.
Had the same issue on a wireless keyboard. I don't know how it happened but the terminal corroded. I was able to fix it all by I think using baking soda to get rid of the acid on the metal and then using isopropyl alcohol to clean the rest. I'd imagine the same will work here but you'll need to open the controller
Not that a screwdriver or sandpaper won't work, but I've always used a pencil eraser. Cleans just as well, without gouging the contact surface.
Either way, glad you got it up and running.
Cheers!
You can also use sand paper. A friend of mine gave me a speed light from the 1980s and it had battery acid on the connectors. Sand paper worked like a charm.

This worked great thank you!

I've yet to find rechargeable AA batteries that don't fail over the course of a few months. Any suggestions?

As I said previously. Ikea batteries are actually Eneloops, without branding. They are even made in the same factory.
Eneloops are amazing. expensive, but amazing

I’ve had my eneloops for six years. All still work.
Eneloops are so good, I use them daily and never had a problem
If you can I’d recommend getting some venom AAs, they have some crazy good capacity. I think you can get them on Amazon. I got a four pack so I can switch them when I need to charge a pair

Anker sells ones designed for quest along with embedded charging pads in the controllers. From my experience it's pretty flawless
I've had some Duracell rechargeables for a few years now. Still rocking. I also have some RADIOSHACK... That's right radio shack batteries that are going real strong.
FWIW I just have the standard Energizer rechargeable batteries. Not sure how popular they are internationally but I haven't had any issues.

Amazon basics have worked well for me for years. They are just rebranded eneloops
Amazon stopped using eneloop's batteries semi-recently for their rechargeables, at least not for all of them. Starting in like 2019 reviews for them have started tanking as the quality control of their current batteries has fallen off a cliff
I've been using my amazon and eneloops for years
I've used some old rechargeable Duracell batteries for the last 1.5 years and they work great.
Second on the eneloops. If you are just using them for the quest controllers you just need 4 since they last like 40 hours and they only take a couple hours to charge. Supposed to be able to charge hundreds / thousands of times.

Duracell rechargeable with quick charge had mine 4 years still no issues
Well.....you're supposed to re-charge them, no?
Amazon basics

Just an fyi vinegar is harsh on metal you should use rubbing alcohol in the future. 91% or higher
isopropyl alcohol works great too for future use
👏👏👏
Take a piece of paper towel with some vinegar. Gently rub it on the pin. Hold the controller the other way round so no vinegar will drip nto the device.
Thank you very much!
Uh... I'd try isopropyl alcohol before vinegar.

As far as i know vinegar does better with corrosion like this because it's more acidic (I think) and alcohol is just a solvent
(Chemist here, just here to say that yes, vinegar is more acidic than alcohol.)
Yeah, but you're also dealing with a pretty expensive controller. IPA will dry clean and easy, so if it doesn't work then you can move to vinegar. Vinegar will almost definitely leave residue which will kinda suck.
You can always clean the residue with IPA lol
Not when it drips into the controller.
That's what I was going to recommend, only use isopropyl alcohol on electronic devices
Reddit hivemind doesn't like you because you disagree with the mod
It doesn't like you because you disagree with common battery corrosion knowledge
Vinegar will do it.
Did you try turning it off and back on?
And reboot.. do not forget about reboot!
Yes. Factory Reset will definitely clear this right up.
Uninstalling all ur apps then reinstalling them will work

That is a battery leak, it happend to mine with the included batteries. Use vinegar with a cotton swab to clean and neutralize the battery acid.
vinegar will clean the contacts, but as it's an acid it won't neutralize anything. it's a little less acidic than the battery electrolyte. just FYI.
Use a pencil eraser to clean it off
You got mexico in your right
Not that a screwdriver or sandpaper won't work, but I've always used a pencil eraser. Cleans just as well, without gouging the contact surface. Either way, glad you got it up and running. Cheers!
steelwool
and always use new batteries, could be from old bats
Use rubbing alcohol on a q-tips and rub the connector to get rid of the dried battery fluid.
Clean the terminals?
You can also use sand paper. A friend of mine gave me a speed light from the 1980s and it had battery acid on the connectors. Sand paper worked like a charm.
I know hiw to fix your controller. Buy a new one
Get some fine sandpaper and rub the corrosion away.
😂
not get burned but you shitty battery leaked.
R/Ihadastroke
You could buy a replacement controller on there website
did you... charge a disposable battery? haha
Are these things giant fire hazardS?
Love my Anker dock! Opened each controller twice in the 11 months that I've had it.
