Why would a company make a survival product without interchangeable batteries?
Three possibilities come to mind:
- Easier to make a water-resistant / waterproof product if you don’t need a battery door with potentially leaky seals.
- Follow the crowd. User-removable batteries are disappearing or gone from all kinds of consumer products – cell phones, cameras, laptops, toothbrushes, dustbusters, …
- More follow-on sales. If your non-removable battery is good for only three or four years, then all those customers must buy a replacement for a much bigger profit margin than a replacement battery. And you can’t be undercut by third-party replacement batteries – or have more problems with flaming batteries.
Luckily almost everything recharges from inexpensive USB external batteries now, so it’s not the end of the world.
