Was going to say this is just a quick video... but nope, my classic rambling style upgrading this cheap Geiger counter (BR-6). Originally, this thing has terrible charging capabilities basically "cooking" the Ni-MH batteries. Why not just upgrade this to use a common Lithium cell? That's what this video is all about...
