[QUOTE="sexy, post: 6380967, member: 612355"] about the only diff in batteries that realy maters to me is that the jell type puts off less fumes for in car use other than that a battery is a battery. unless of course you sell batteries then the one you sell is this best with out a doubt. as for voltage you alt is factory set to 13.8 or 14.4 depending on what car you have. if you were going to run 16.6 volt you would have to have a seperate circut for your amps so as not to burn up your ECU. to see what needs you have just check voltage at the amps it should not drop much below 14 volt with the system cranking at three quarter volume for several minutes. no amount of batteries or brand of batteries is going to produce magic power power comes from the alternator. now if you were wanting to run you music for a long time with the engine off thats a different story in that case you would need extra batteries but then you would have less than 12 volts to the amps at all times. a 12 volt battery has 6 cells each stores about 2.01 volts resting and while being charged a chemical reaction takes place and each cell producesses 2.4 volts (2.4 x 6 = 14.4 ) [/QUOTE]
