Re: Xps 9550 battery swelling causing malfunction and harm?
This is an issue for ALL systems using batteries of this design. Not surprisingly, it started with Apple, which was the first to use them.
The only way to avoid the issue completely is to avoid any thin/light system that uses a battery sealed in a plastic envelope - and there are VERY few notebooks now that don't use these. Just about the only ones in widespread distribution are some of the T-range Thinkpads and some large gaming systems from Clevo. If you don't want the spectre of a swollen battery, these are your only options.
For everything else, the batteries will swell up at life end. At the first sign of the issue, the battery should be replaced immediately.
