Looking for input regarding swollen battery (Dell XPS 15 9560 2017 model) 64-bit

Specs: IntelCore i7-7700HQ CPU @ 2.80Ghz, 1TB SSD, 2x8gbDDR4 RAM so 16gb RAM

TLDR: Have had a protruded mouse pad and dead swollen battery for well over a year, maybe almost 2 years with resource-heavy use on a daily basis with no issues (other than a burning smell noticed well over a year ago leading to non-stop recurring BSOD issue which I have since fixed.) No noticeable performance issues since. Spoke with Dell Support. 5XJ28 battery model not offered by Dell, and other options offered online with very mixed reviews. Wondering if it is worth it to buy a new battery and replace it, as I am not bothered by the mouse pad since I use a wireless mouse, and seems nothing internally was severely damaged.

Hi,

So I first noticed my mousepad raise probably over a year ago and did not even think about the possibility of it being caused by the swollen battery. I should have definitely looked into it more at the time. I have the orange flashing light and if I unplug my AC adapter my laptop shuts off (dead battery). There was a period where I would constantly get Blue Screen shutdowns, but I spent hours going through different solutions and managed to find a fix, and since have not had a crash in at least a year I would say. I did at one point notice a burning smell (before the constant BSOD), so I quickly turned it off, sprayed it with the laptop cooling spray, and let it sit for a while before attempting to use it again.  I have not opened my laptop yet to see if anything was seriously damaged internally, but besides the issues with BSOD following that, which I have since fixed, I have had no problems with the performance so I am assuming the motherboard, graphics card, and RAM are fine. Have run diagnostics, installed Core Temp to monitor my battery cell temperatures, and get notified if goes above a set temperature. 

I was completely unaware the protruded touchpad was the result of a swollen battery until my brother pointed it out to me recently. I then googled the issue and saw how common it was and that Dell supposedly offered free battery replacements regardless of whether the warranty had expired for models in which the battery swelling occurred. Also, read not to use any device with the issue, but I have been using it for some pretty resource-consuming tasks for the past year (video editing, rendering, music production with FL Studio, virtualization running several OS at the same time, and many other things) and have not noticed any issues or any more instances where I smelt something burning. I called Dell support after reading about the many cases and asked about the no warranty battery replacement, and was told my battery model is 5XJ28, and the support rep offered to transfer me to another support for this issue that would cost $60 or something just to talk to them about battery replacement (not for them to offer a replacement, but to walk me through how to replace the battery, which I declined because I know how to deal with hardware. Since there are no actual Dell replacements offered by Dell for the battery available, and, as far as I have seen, third-party sellers on Amazon, ComputerParts, NewEgg, etc. with some having very mixed reviews. I use a wireless mouse so the pad being protruded does not bother me much. I will most likely be buying a new laptop within the next year anyway, and am fine with using this as my "Desktop." Also since I have not noticed any glaringly obvious performance issues, all ports work, etc. It is fully updated and seems the only issue is the battery. Does not seem it poses a threat of exploding anymore, as long as I keep it on a hard surface. Have it connected to Dell P2720DC monitor and that has not brought upon any issues either (have also used it with Seiki 40" 4k monitor with no issues). Dual booted Ubunutu disk partition. Just do not want to buy a $200 battery if it is gonna die in 2 months or only last 45 minutes unplugged, when I really only use it as a desktop right now anyway. 

Any advice, people in similar situations, would be much appreciated
