I still have the roto start on my Savage 25 (Cuz pull starts are nothing but probs for me) and when I charge the battery it reaks really bad. The box thing that plugs in the wall gets really hot and if I leave it on for a while the battery gets hot also. Is this normal? My other charger was a rapid charger and the battery would get a little warm but wouldnt smell like this. Smells like a electrical fire.. I have two different batteries and it does it for both.. Is this common? Any ideas? or should I go get a new charger?
