well how many yellow tops can u get for the price of an alt? if u can get 3 yellow tops for the price of the alt i would get 3 batteries. but if not i would get an alt.
if the yellow top batterys cost more the 100 each new i would go with XS or battcap or a car audio battery. shit u can find deka 31s for 200 each new most places.
