On: Building replacement proprietary battery packs

When companies do use that approach, they usually include a warning insert about not shorting, mechanically abusing, or eating the battery. Li-ion cells aren't very difficult to handle safely, especially in single-cell applications. This has gone well for flashlights, but has yet to be widely adopted in other product categories.

I understand that major consumer-product companies are reluctant to offer a product with any risk of attracting personal injury lawsuits, but I'm still classing it as a bad reason.
