A couple people have said that if you add a 2nd battery that it needs to MATCH the main battery/starter battery. However, some people say that it does not matter. Which is right?
this is true but you must also use the same type of battery ie .. agm ,wet cellThe main thing is that the resting voltage of both is relatively close. The stronger battery will try to charge the weaker one when your vehicle is off.
The battery I want to use is a deep cycle battery. Its a Stinger SP800this is true but you must also use the same type of battery ie .. agm ,wet cell
