The batteries are stuck in my trackpad!

Same thing - but remedied when corrosion/bulging only on the first battery inserted. Long sharp screw inserted into a pilot hole on bottom of battery solved the problem for the time being - there are still corrosion crystals that I tried to completely remove with WD 40 and a tube of fine sandpaper. Trackpad now works as before, but rather than drilling into corrosive alkaline I think I will just replace the trackpad if it happens again. Seems batteries are the way wireless works these days, but I too would like to see an USB port for use during battery issues. The kind of battery probably does not matter, I have had popped cases and spilled contents in many of my battery powered thingies and I am quite fussy about purchasing top rated battery brands.

Here is is end of November 2017 and I have discarded the numeric pad, and the keyboard also later had expanded and corroded batteries. I was off to the Apple store to see what solutions have emerged, and for a $120 bill or so, I replaced these battery powered peripheral with a keyboard unit incorporating the numeric pad and the keyboard in one, powered by Thunderbolt to the back of the iMac. Much better solution - but have pretty much given up on using the Trackpad, as it is still battery powered.

My rechargeable AAs swelled up and could not be removed. I drilled a hole in the end of the first one and pulled it out with a screw. Unfortunately, BOTH batteries seem to have swollen, and there's no way to get the second battery out. So I'm afraid my Magic Trackpad is junk. (I wish Apple made a USB-powered version.)

Beware of "iGoGreen" batteries (purchased from Woot.com)!

The screw trick worked great. I had both batteries (duarcel) swell up in my track pad and against my wifes wishes I drilled into them with decking screws. The second battery required a long 4 inch screw to get to but it worked like a charm. Thanks for the advice.

I've the same problem, I'm going to try the "drilling" technique mentioned above. Did your trackpad still work after removing the batteries or had the corrosion messed up the circuitry?

Thanks for that tip!! I had the exact same problem using Duracells (what **** rubbish batteries!!!) and the second one would not budge.

I drilled a hole in the bottom and used a drywall screw as shown and it was a ***** to pull out. I had to use varying pieces of plastic (a wire brush handle) to use as a fulcrum for a Leatherman pliers to pry it out!!

I used contact cleaner and sand paper wrapped around a Phlips screw driver to get rid of the corrosion inside and then sprayed some WD40 to stop any further corrosion.

I dropped new batteries in and it still works thankfully!!

Thanks for the suggestion. These are the batteries that actually came with my track pad. I made the foolish decision to recharge them even though they aren't rechargeable. They worked fine for about a month until they swelled slightly. The first battery slid right out, but the second one was jammed in there.

I drilled a shallow pilot hole then used a 2 1/2 " deck screw - it slid right out when I pulled back on the drill.

You should not buy nor magic trackpad or keyboard, ever !!! I won't buy anu more !!!

Hey, you have no idea how helpful was this post.

I was just siting trying to take out this battery.

Thanks A LOT!

The pilot hole and a screw did the trick to remove a leaking Energizer alkaline battery. Mahalo
