A childhood belief about tv shows

when i was really little there was this TV show with Lee Majors... i'm pretty certain it was The Fall Guy... so in this one episode, him and his sidekick were driving through this desert with bad guys chasing after them... so the sidekick is holding these batteries like hot potatoes and he's throwing these hot batteries out the window at the bad guys... and they were exploding and blowing up the cars that were chasing them!

so i asked my mom if batteries would blow up if you threw them... and for whatever reason she was like "yes, don't ever throw batteries! thats dangerous..." and that was all the proof i needed... i thought for years that batteries were like bombs and would explode if i dropped them or knocked them too hard...
