what exactly is a starting battery? i was reading a description of a blue top starting battery and it said it was for starting only.. does this mean it wouldnt be able to keep up with my electronics? (2 amps for a total of 600watts RMS, 4 LED bars, 7" monitor and upgraded head unit + 300 watt power inverter on occasion.. always drive with headlights on) or will i need to get a yellow top to be able to handle the the load?
