>My Surface had a swollen battery which killed the device.

Statistically, all devices suffer from swollen batteries. I've even see iPhones and iPads die from swollen batteries. There's a certain tiny % fallout in manufacturing of battery cells where they may degrade and fail prematurely and swelling is a safety feature.

I had two surfaces die from swollen batteries. The problem was frequent enough that Microsoft Store staff (rip) would exchange it immediately, no questions asked.

This was back during the Surface Book 1 days. I’ve been a happy surface user ever since, and haven’t had any other battery or build quality issues since.

Eventually, almost all LiPo batteries will puff up. But there are definitely some devices that reliably cause this problem far sooner than it should occurr, due to poor charge management and thermal management.
