my battery does appear to be holding a charge. i dont think its the alternator; my `84 240 wagon runs fine when its started, but even turning it off at the gas station will leave me needing another jump.
i have a heavy duty inverter in my car which is unused, lacking a deep cycle battery. i use it every now and then to power up my laptop. my question is, can you crank off a deep cycle battery? i'd rather buy one expensive battery than a starter+expensive deep cycle. i just dont know if deep cycle batteries have problems providing high drain cranking.
does anyone have suggestions for deep cycle batteries? the optima blue and yellow tops are $110 at pep boys. i'm half tempted just to do that.
if i need a seperate cranking battery, what should i expect to pay?
thanks a million Myren
