Allow me to throw gas on a very small fire. My ‘46 GMC is a “shed queen”; and rarely gets out to stretch its legs. Maybe 6 times in a year, and most of those times is a 5 mile loop to circulate the fluids.
Not very happy with 6-volt starting; the owner of my local battery warehouse suggested an 8 volt battery. That was 1997. I have used nothing else since. They last 6-8 years. I bought an 8-volt battery tender and that stays hooked up 24/7.
The truck turns over like it had 12 volts. We adjusted the voltage regulator to 10 bolts, which charges the battery and does not blow any bulbs. We do not have a radio.
As they say: You pay your money, you take your pick.
