You could get a new battery from a known good source (or light a couple on fire to make sure they’re not explosive). It should be relatively easy to check the rest of the components for anything near a dangerous amount of explosive, and the body can be replaced with a custom one and/or subjected to the fire test.
Even a fire test may not produce accurate results (see C4). Better to not have distinct supply lines from the civilian population you’re already hiding in.
