No, but disassembly can be very risky by way of snapping retainer tabs, especially on anything meant to be waterproof and seamless tot eh touch. As good as I've gotten over the decades, such things always tend to show dents and scrapes from my pry tools. But I can also commit to that risk as well as the compromise that I may have to glue it together after the fix, making it a final fix.

It's not the battery (although it does take an uncommon battery, a 14500), it's the disassembly.

You need to soak the base in hot water to soften the plastic clip, then use the charging stand to break the seal and open it up. Once open, there's a delicate metal brackets to unclip and remove. At that point, you need to desolder the battery and the motor, and then start to work on the plastic brackets. This is less than halfway through the process, and it's likely broken.

Some things are extremely repair-hostile. I'm not happy about it, but I'm not going to spend half a day attempting a very unlikely repair.
