    I don't usually use my Magic Trackpad, so I leave it turned off. Looked at it today and noticed what I first thought was dust around the battery compartment opening. I wiped it off, and then realized it was from a corroded battery. I tried to open it, but it is sealed shut. Even used a large screw driver (which dinged up the cover a little) and it won't budge.

    Anyone know of a way to loosen the end cap?

    I've got the same problem

    I didn't use my trackpad very often either. I tried to open it once to change the batteries and couldn't so I just left it. Then I noticed the same dust, from an exploded battery. I tried to use a coin to open it like it says on the apple website but it won't budge. Help anyone?

    Took it to the Genius Bar today. They didn't even try to open it or anything, basically told me it was ruined and I had to spend $75 on a new one because I'm out of warranty. So they did **** all. Some genius' they are. I'm pretty sure I'll get it to work if I change the batteries but have to get it open first. I'm going to keep trying and I'll update if I fix it.

    I'm hoping this will help someone else in the future like there wasn't any thing out there to help me.

    I am in the same boat. I have it open but the batteries seem welded in. I am thinking of a drill once I secure the track pad in a vice with plenty of padding.

    If u use the trackpad and swap batteries often, no problems at all.

    Love a good Alkaline Battery Story.
    Eneloops came out, what 7-9 years ago?
    Just sayin' - Guess you need to be around long enough
    to have your first "Acid Freeze" in a flashlight or toy.

    Now Ya Know ;)

    How much elbow grease did it take? Think mine might be too tight to get any WD-40 in there

    you can try using white vinegar to dissolve the will do a better job than WD-40.

    Some tips from a flashlight forum (adapt them to fit your situation as appropriate - I would try the vinegar first to get rid of as much corrosion as possible - then try the screw pulling technique):

    How to get the batteries out that have corroded:

    1. Find a #10 self tapping hex head steel screw 2" long.
    2. Measure down the barrel how far the battery is.
    3. Get an extension for your drill (battery drill prefered) to allow the screw to be power screwed into the battery.
    4a. Before power drilling the self tapping screw into the battery, ensure that you have some very long needle nosed pliers or vise grips that will reach the screw, otherwise figure something out that can pull the screwed battery out, e.g. small chain, or steel wire.
    4b. Pour some 3 in 1 oil down the barrel to assist the release of the battery. Ensure that battery is adequately flooded with oil.
    5. Place maglite into bench mounted vise. Wrap something soft around it first, such as an old towel or rag. Make sure that the vise-gripping area is NOT at the same location as the stuck battery.
    6. Power drive the self tapping screw into the battery. If using a small chain, put screw through end of chain first. (may have to use a few washers, etc..)
    7. Make sure that you can pull with lots of strength and the maglite won't pull out of the vise. (test pull the lite)
    8. Pull the battery out of the barrel using vise grips grabbing the screw, or the chain attached to the screw.
    9. With the battery out, flush the barrel with isopropyl alcohol to get the oil out. Allow to dry. OK to jam a rag down there to dry also.
    10. Take a broom handle and tape some 80-100-150 grit sandpaper to it. Sand the inside of the barrel to remove corrosion. Gently test inside diameter of barrel with another non-leaky junk battery.
    11. Flush maglite with lots of clear running water to remove debris. Flush with isopropyl alcohol to absorb water, and let air dry overnight open.
    12. Reassemble the next day.

    Note that even if you wreck the trackpad getting them out - if they are name-brand (Duracell or Energizer) you can contact the battery mfgr and they will replace the item that was destroyed (see their website for their guarantee).

    What miracles were you hoping for, seriously?

    Batteries, especially cheap ones, tend to leak and mess up the electronics. I am confused why the trackpad is the problem in your opinion?

    If your trackpad battery compartment is sealed shut do not try to open it. It takes tremendous amount of force and messing up with chemicals. At the end of the day, you will either not be able to open the compartment or in the process damage the trackpad. I just spent the whole weekend doing the same thing and then grabbed my tools to do the job. I now have a slightly damaged but fully functional trackpad with no worries for a future catastrophe. The pictures below will give you the entire story and the way out. The slot will be covered with a plastic sleeve. The tool used was a dremel rotary tool.

    Since you had Duracells that obviously caused the damage and have photographic proof - go to their website and look up how to take advantage of their guarantee. They will send you reimbursement for a new trackpad.
