I have a Magic Trackpad 2 with a swelling lithium battery

Is there a replacement battery available for the Lithium Ion battery in my Magic Trackpad 2?

I recognize that this swelling is a potential fire hazard.

Further information: The battery is a TIS 2217-2548 Apple South Asia (Thailand) Limited Product, Lithium Ion Polymer Battery

Another question: Will the Magic Trackpad 2 operate with the battery disconnected or removed as long as it is plugged into my MacBook system?

My Magic TrackPad 2 Lithium Ion Polymer battery swelled to the point where it detached the bottom plate of the unit!

I decide to remove the battery from the unit. I detached the plug unit from the circuit board and the bottom plate was free A little glue softener allowed the three patches of double stick tap holding the battery to a black aluminized heat sink on the bottom plate to detach and the battery is free.

When I put the bottom plate back on (without a battery) and plugged it in to my keyboard. It works perfectly with the exception that I am getting a low battery symbol beside the Bluetooth rune on dashboard.

if you "carefully" remove the lithium ion polymer ion Battery from your Magic Trackpad 2 you can go on using it just not as a stand alone wireless device. Why Apple saw the need to do away with the 2 AA batteries in the old Trackpad for the lithium ion polymer battery is beyond me

Anybody have source for a replacement for a TIS 2217-2548 3.78Vdc 2024mAh battery in the USA

I took the battery out with no issue, but the function is not the same. There had been a clicking motion that is not gone after removal of the battery and its hard to select in right click from the menu. Perhaps I did not put the parts back together, but I thought it was pretty simple.

So the forcetouch is disabled without the battery. I might have been nice to say that as a warning.

@davidgruenberg ye, I found it today. I checked twice, if battery removed, taptic engine not working via cable without battery. A little upset about this. But the battery was so swollen that the back cover partially fell off, and the trackpad wobbled)))

I know the Magic Keyboard of the same era works without a battery, if kept plugged in with a lightning cable, so I'd expect the trackpad too as well.

You can get a battery for the Magic Trackpad 2, but I have only been able to find listings on AliExpress, or similar so I cannot speak to the reliability of these parts.

As for whether it can run on USB cable alone, with no battery, I’m not sure. I’ve honestly never tried. It logically makes sense that it would. But my logic is by no means infallible.

^ What they said. On small devices it's a crapshoot whether it will work without a battery or not. You'd think that sensible design practices would say it should be able to work on AC power or battery for anything that incorporates charging, but I have a few things that have proved that's not always the case.

My electric shaver, for example, won't run if the battery is dead, even when it's plugged in to the outlet; not until it's charged enough that the battery can run the motor.

@dadibrokeit ^ What she they said. Please and thank you. :)

And yes. It's nonsense sometimes what will run straight off the wall adapter, with no battery, and what won't.

- de

Ah, my apologies. Corrected now.

@dadibrokeit I get it. Pronouns are a weird thing. And not readily obvious.

Although, honestly, I appreciate that you used she/her… which sounds weird given that I have eschewed “feminine” signifiers being used for myself. But I get “bro” and “man” so often in repair spaces that I almost just let it slide. So many people affiliate repair knowledge with “masculinity” and it was nice to see that isn’t always the case </rant about my gender and not so vaguely misogynistic trends in repair spaces>.

My Magic TrackPad 2 Lithium Ion Polymer battery swelled to the point where it detached the bottom polymer (styrene?) plate of the unit!

Before the battery bag slits and the battery possibly catches fire I decide to remove it form the unit. I detached the plug unit from the circuit board and the bottom plate was free A little glue softener allowed the three patches of double stick tap holding the battery to a black aluminized heat sink on the bottom plate to detach and the battery is free.

I discovered an interesting thing about the trackpad2 when I put the bottom plate back on (without a battery) and plugged it in to my keyboard. It works perfectly with the exception that I am getting a low battery symbol beside the Bluetooth rune on dashboard.

This means that if you are willing to "carefully" remove the lithium ion polymer ion Battery (time bomb) from your Magic Trackpad 2 you can go on using it as a plugin device just not as a stand alone wireless device. Why Apple saw the need to do away with the 2 AA batteries in the old Trackpad for the lithium ion polymer battery is beyond me (except perhaps that the engineers though it was cool).

Anybody got a source for a replacement for a TIS 2217-2548 3.78Vdc 2024mAh Apple Japan battery in the USA or at least short of the PRC gray market?

Now, that's the kind of comment I've been looking for. Thank you, Richard!

This trackpad has been sitting here doing a good imitation of an opening clam, while I try to figure out some useful way of dealing with it, rather than taking it to hazardous waste.

Consensus seems to be that the battery isn't feasible to replace by any reasonable method. But, knowing that the unit will work without the battery, makes that project possibly worthwhile. We'll see 'what it looks like'/'what I think' once I have a moment to remove the battery.

I hate throwaway mentality...

And, thank you, Gwendolyn, for giving us some insights into what any adventures into the innards of this trackpad might entail...

Thank you!

Larry:

You are welcome!

Here is a q quick update:

I've been running the Magic Trackpad 2 without a battery since the battery pried open the styrene back panel by swelling and my original post.

The Lithium ion battery was relatively easy to remove with some tape adhesive solvent and once un-stuck simply unplugged. The trackpad back cover morphed back into its original shape with the swollen battery gone and the trackpad works perfectly except for displaying a dead battery symbol on the header. There is no reason to be afraid of a careful battery removal and doing so will save the unit from the recycling bin as long as it is used plugged in. Honestly I still prefer the AAA battery version of these devices. But of course they don't self destruct and need to be replaced.

Honestly I don't understand why Apple cannot either ditch lithium ion batteries or make them more easily replaceable?

I don't want to order a pig in a poke from AliExpress. Maybe IFixit Should source a battery replacement.

Hi,

the same issue happened to me as well with the battery (swollen and pushed the back out).

But now without the battery I don't have any click feedback. Everything apart the feedback is working ok!

I have connected the battery back and tested it, and the click feedback is working.

Obviously the expanded battery for one does not fit the device and of course there is a hazard of some injury as well I guess.

Do you have the click feedback on you pad without the battery?

I just made this repair using the battery listed here. The battery took 25 days to reach me from the time I ordered. My old battery had swelled and pushed the back of the case open, so the backing was easy to remove.

I just replaced my swollen battery with this same one from AliExpress, and it works fine. But just as the teardown explains, getting the rear panel off the trackpad is a nightmare. I used a hair dryer to soften the glue a little, but I spent the whole time worrying that I was going to bend the panel beyond its breaking point. Fortunately, it all went well. The glue kept its stickiness, so that sealing the thing back up again was easy. I would definitely have preferred tiny screws for this!

I removed battery and taptic engine not work... I checked twice, if battery removed, taptic engine not working via cable without battery. All basic functional working properly just connect via usb cable.

I experienced the same issue. The haptic component (Apple's Taptic Engine) no longer worked when I removed the swollen battery from my unit. It's not a big deal for me because I didn't find it that useful. But it is something to be aware of if you want to use the unit without a battery.

Have you tried adding a spacer to fill the space? Maybe a piece of cardboard with aluminum foil taped to both sides to mimics the capacitance of a battery (if it isn't detecting the force)? I'm thinking out loud here, but it would be worth trying some things like that to see if the missing functionality is an electrical issue or a mechanical one. Also, try a heavier-gauge third-party lightning cable and a higher-amperage power supply. When pulling power from your computer, the device probably caps itself at 500 mA, but the Taptic Engine may draw more than that in instantaneous power.

Like others here, my trackpad's battery swelled to the point of pushing open the backplate. I picked up the battery Patrik linked from AliExpress and performed the repair. The battery arrived in 25 days.

The backplate open:

I cleaned off the adhesive and installed the new battery. I clicked the backplate into place without adding more adhesive. The backplate stays in place on its own when sitting on a desk.

And, it connected without issue:

All features work.

When I received the replacement battery linked above, it arrived totally unmarked or identified from what looked like Mr. Li. The battery initially looked far too long for the trackpad, but when I finally got around to getting the trackpad out for inspection, I was delighted to discover that the battery’s length was perfect, and indeed the cable and socket configuration appeared to be the same as the swollen one beneath the gaping wound in the trackpad.

The only thing that took any time was convincing the old battery’s adhesive to surrender. After placing new adhesive on the new battery, everything went back together quickly and effortlessly.

I knew that I preferred the trackpad to Apple’s curiously miserable Magic Mouse, but I wasn’t prepared for the sensual delight and ease of zipping the curser side to side on a large screen with one finger precision and less effort than it takes to say “effortlessly”!

My thanks to everyone who contributed to this outcome, including Mr. Li!

Be very careful when prying open the plastic backplate. The adhesive is very strong, and even the iOpener doesn't soften it very much. My battery was slightly swollen and the backplate was still very firmly attached. I used a X-acto blade to help pry open the bottom, which took considerable effort. Instead, I would avoid using a blade and go for opening picks or an iFixit jimmy. There isn't much space on the sides to pry open the device, and I accidentally punctured the battery, releasing the Lithium gas and smoke. Luckily, the battery didn't have much charge left, avoiding a fire, but I still breathed in some of the toxic fumes.

There is no reason for Apple to use adhesive for enclosing the device when screws would have accomplished the same function. I hate Apple. This is the only Apple product I own because no one makes a trackpad like this and using this instead of a mouse helps mitigate RSI. I hope I never have to buy another Apple product for the rest of my life.

That's pretty strong language, Yatin. Apple certainly gives us reasons to call them on a surprising number of choices, but are you saying you're more satisfied with the universes of Android and/or Microsoft? I'm under no illusions that Apple is perfect—far from it. But hate is a one-way, dead-end street, with no way out, other than putting it in reverse through the understanding and power of love alone. It leaves us cast in cold stone.

Apple chooses to use strong adhesives for their cases for a number of reasons some good and some not so good for the consumers of their products. In the case of my magic track pad the adhesive was overcome by the swelling battery.

I still wish a replacement battery was available outside of the PRC. There is no reason for apple to make these accessories unrepairable by the average customer. The back could be secured by a waterproof adhesive and screws and removable and repairable and replacement batteries could be made available. I just set up a new MacBook Pro for work and it has a new magic keyboard and Magic TrackPad2. We will see if the battery on this one swells too?

I do think that Apple is open to legitimate criticism for their repair reuse policy. My position is that once I pay for my Apple products they are my personal property and I can repair them as I choose and Apple's no consumer repair policy be damned.

@richardleverett, I understand what you are saying about adhesives in general, but for this specific device, adhesives are not needed. Water resistance can be achieved using a gasket and would probably work more effectively. The decisions Apple is making on the design of this device are geared toward preventing user serviceability, plain and simple. Gaskets can be replaced and allow for easier access without the risk of damaging the device or your safety.

I 100% agree with you on ignoring Apple's anti-consumer policies.
