TH-D74 is a really cool radio, but it's a bit of a battery hog. If you're going out for more than a few hours you might want a spare battery with you. This is a cover to protect the internal terminals.
It also have an indicator switch you can toggle between E and F to help you remember the charge status of the battery. It can also be charged in the cradle with the cover on.
Just keep in mind it doesn't cover the outer terminals, but they at least have a bit more spacing.

The switch benefits from a color change to get some contrast.
