Why Is My Battery Smoking In My Car. Its a very small window to find but use a water bottle or canteen to fill the radiator. Either one of two ideas.

Place it in a safe location. Oo and other good news my left headlight bulb jus blew magically. Ok i had my alt.
Up to 20 cash back Disconnect the negative battery cable and let is sit again the in 15 minutes or so disconnect the positive cable and remove the battery.
An overcharge occuring from the alternator. Loose connection smaller touching surface area to draw lots of amps through very very hot and possibly smoking mo_dingo Well-Known Member. When I started my car I heard a loup pop and smoking coming from the battery. If an alternators voltage regulator is beginning to fail or has failed the alternator can begin to send too much voltage back to the battery which in turn causes the battery to overheat.
