Using vinegar or lemon juice (both acids) will help to attack the corrosion. However, you should use baking soda and water mixture (a alkaline solution) to neutralize the acid(s). Personally, I would first use the baking soda mix to neutralize the battery acid. Then you could use the vinegar or lemon juice to clean the aluminum surfaces. Finishing up by using the baking soda mix again as a final process to remove all remnants of the acid. Aluminum is not a stable material, if you wipe your finger across raw aluminum, it will turn black. This is due to the fact that aluminum is always oxidizing. Once the aluminum has been ate away by the acid, the acid has eaten away past the sealing finish of the aluminum. Those surfaces need to be sealed once again or they will just continue to corrode. After the second baking soda process, I would clean the surfaces with Alcohol. Then have a small amount of clear coat paint on a q-tip and wipe the surfaces with the paint. Let it dry and reinstall batteries.
Just wanted to share a technique tht worked for me to get my trackpad open without damaging the glass. I used a tiny screw driver as a wedge/chisel and hammered it in all around the edges of the screw endcap. I think the hammering helped loosen the corrosion.
Tried opening mine with a quarter and pliers, but the trackpad flexed slightly with all the force I was applying and so the trackpad glass cracked all the way across, so now I have 2 problems to fix! Just bought 4 non working ones for parts off eBay for $25 - I must be able to salvage one working unit out of it and still be better off than having to buy a replacement (I hope!)
I fought the corroded battery in my Magic trackpad for an hour when one of these videos inspired me to use my table saw to cut an 1/8" slot on the bottom side of the batt compartment giving access to the batteries where the meet in the middle. Inserted a screwdriver and pried the batteries out! SUCCESS! Then while proudly cleaning up the inside and out I dropped the thing on a concrete floor shattering the glass, had a laugh and threw the mess into the trash. Done... go back to real work now and quit farting around.
Same problem here. The batteries were so stuck in mine that I had to drill a hole into the center of the battery, drive a screw into it, and use pliers to pull the battery out. Battery juice + aluminum really makes for a bad time. I'm only using NiMH from now on.
Using a nickel in the slot with pliers to turn the nickel while simultaneously tapping on the nickel with a light hammer was the only thing that worked for me. I fought mine for an hour before the tapping finally did it. I think the tapping loosens the corrosion that has locked up the threads. Careful with the tapping though, because the trackpad surface is glass and will shatter if you hit it or if you put too much pressure on it. Also, the joint where the trackpad glass and metal meet will bend if you wrench too hard with the nickel/pliers, so watch out for that. But try the tapping. It was the key for me.
It's the tapping while turning that did it for me. Gotta do something to loosen up that calcification in the threads. It's probably really bad on yours. Just be careful not to shatter the glass. I found that a nickel was the perfect size to get it turning.
@@JerryFerguson figured mine out! It was a 2-battery keyboard (I thought it was 3). The receiver inside look JUST like a battery and it looked possibly corroded. Tip: don't try to take out the receiver haha. Felt like an idiot when I figured it out!
I am encountering the same issue, thanks for your input.
I couldn't open mine but thanks for sharing your solution.

Any updates on that?

Great! But whats the voltage of the battery? 1,5v or 1,2v?
Awesome! Thank you! You just saved me a ton! All the best.
thank you so much for the detailed well-presented video 😍😍😍 now mine works like a charm
Whats the tension voltage of the battery? Is it 1,5v or 1,2v?
Thanks so much for this, although I cannot get the cap off. Ahhh so aggravating!

@@JerryFerguson Thanks! I'm still slowly working on it. I refuse to trash it! Thanks.
@@ashleymullis9539 please let me know if were able to unscrew it. Thanks
Locking the hell out of it with a hammer works well.
Coins wouldn’t work for me. I gave up and used a screwdriver. It was still a bit of work, but the cap finally unscrewed.
It worked ur a life saver thanks
Which batteries to use?
I couldn't even take the metal cap out. Have been trying with hand and electric screw driver and have broken a couple quarters :(

This helped me, thanks
Great Video! Thanks.
Will putting the vinegar inside damage any components?
It could, but I figured it can't get much worse than having a corroded battery in there.

cant take off the cap of my magic keyboard, solution? buying a new one.
Solution: buy products from companies that make products that last and are repairable :-p
Same
I had to use a corkscrew and pierce them to pull out
Man I shattered mine trynna get it open
ME TOO I'M CRYING
Hhhhhhhhhuuuuuuuuu goo
