Same issue here... one month out of warranty, the battery starts swelling and the trackpad is useless. Dell have offered to replace the battery for free, but I've had no indication of when that might be as they are out of stock. The best I can get out of them is that it might take weeks.

Great that I get a new battery, but I'm now stuck with a laptop I can't use unless it's plugged in. Not what I would have hoped for, for such an expensive pc.

I too have suffered this issue on a £2000 16 month old laptop and reported it to the ultimately useless Dell Cares (what a misnomer!) via twitter.  They followed it up, I sent pictures of the battery and they responded that it's not a safety issue and as the laptop is out of warranty to contact them for an out of warranty repair!  When I asked what the criteria they were using to decide it wasn't a safety issue they couldn't tell me.  They could only tell me that it was safe.  They even said  there was no risk to me or the laptop in putting the battery back in and carrying on using it!  This is utterly ridiculous and has ensured that I will not be buying Dell again.

Same problem here just 3 month after my warranty has expired. Battery unplugged in fustration.

I´m a former IBM/Lenono user and did never have problems finding and picking up spare parts if necessary. Apparently this is not an option at Dell.

Same problem, out of warranty for 6 months.  This is ridiculous for such an expensive computer.

I'm writing this on a 10-year-old iMac because the battery on my <2-year-old XPS 15 just pushed my trackpad clean out of the computer. I agree with you all, totally and completely unacceptable on a "high-end" laptop. First and last Dell I'll ever buy, for sure.

Same problem here, out of warranty for 6 months.I stick with using the laptop with external power.

You should cal 1-800-822-6031 (the DELL out of warranty support number). They have confirmed this is a known issue. They will be replacing the battery free of charge due to this being a known issue. Please call Dell ASAP as having a swollen battery is a huge safety concern.

There is a replacement battery program for the "Precision 5510 and XPS 9550 swelling system battery".

That is very good news,

I got told over the phone they would repair it free of charge but they could not do it due to a system problem.

Its unfair that they are willing to change it for some (whether they change the battery or the whole laptop) but for others they won't do a thing.
