The inside bore near the battery cap looks a right mess, but it is clear of all potassium hydroxide residue. I used the file, pick, and fine emery cloth wrapped round a pencil to clean up the bore, finishing off with a detergent soaked rolled up kitchen towel and a final drying stage. The innermost end of the battery tube looked OK, as did the positive contact at the bottom of it. Apple bluetooth keyboard batteries stuck free#That was messy, although it came out in one piece! The second battery was free to move, but would not come out past the residual gunk on the inner bore until I scraped it off (using a dental pick to clear the threads, and a small file to scrape clear the bore). I drilled a small hole in the negative terminal of the first battery, then used a corkscrew to get it out. Then I clamped a large flat-blade screwdriver in a bench vice, and unscrewed the battery cap by turning the keyboard as KWVarde suggested, using brute force & ignorance (plenty of ignorance). I used domestic appliance descaler (concentrated acetic acid, I think) to disolve the worst of the gunk as in finddarkpoet's first picture. I had the same issue, on a keyboard which is no longer used very often. The keyboard took a serious beating, yet now shows no signs of it, except a rather marred screw surface □ *Huge testament to how these devices are constructed. There is still some caking on the surface and the threads appear to have been somewhat dissolved from the battery acid, but that doesn't mean things are beyond repair. I took some care to really soak the areas, listening to the fizzy reaction, and making sure all the contacts had been treated. I thought I'd destroyed the electronics and gave up for a few days until I figured I'd give it one last shot.Īfter taking a q-tip doused in vinegar (expensive red wine vinegar, at that) and cleaning the threads on both the compartment and the cap, it all worked again. What I hope to add here is that even though I could get new batteries into the compartment and had thought I'd cleaned everything up, the keyboard wouldn't power on. Scraping the acid away with a screwdriver allowed me to get the batteries out after some considerable banging on a soft surface.* I managed to get the compartment open after applying huge amounts of torque, but the threads on the inside were caked with battery acid and getting the batteries out was a huge pain. The batteries are out, but I still have to clean all the corrosion residue before I attempt to replace batteries.įor the benefit of other people looking at this thread with similar issues: I think I even applied WD40, and finally got it unscrewed. I had to do a lot more vinegar soaking, empying and soaking again to loosen the threaded screw. Then poured more vinegar in the compartment and after soaking for a while, I used the hammer again to get the second battery out of the same center opening. Interesting that there was not much corrosion but the battery seemed to have swollen. Slowly, one battery started coming out of the center opening, then I pulled it out with pliers - was really stuck. Then, I wrapped the screw end in a towel and started hammering it while holding the keyboard on a carpeted surfaces. I followed the suggestion above (same way as show in the posted photos) and removed the electronics, then soaked both ends of the battery compartment with vinegar and baking soda, but nothing really helped except maybe loosen a little.
