hey guys, I need a new battery for the 27 coupe, is it ok to install an 8 volt battery, and what kind do you guys use? thanks in advance mike
6v ones work fine, if you have heavy cables and clean connections. You can get those at any tractor supply store.
Oh boy, here we go again. I use a six volt Super Start from the local farm supply. Why eight? Why not just fix what's wrong?
If you insist on an 8 volt battery, just adjust the brushes on your generator to charge slightly higher. My Dad did this on our 27 coupe and it will spin the starter a little faster, but we still needed to jack up one rear wheel off the ground, often. We found that 8 volt batteries don't last any better than 6 volt batteries. Of course that was before the modern battery tenders became available. As long as you don't set the charging rate, too high, you can use 6 volt bulbs.
I doubt you will find an 8 volt battery that will be superior to a GOOD, 650 CCA, 6 volt battery.
I bought a store branded 6 volt, 650CCA last year and it has served me well so far. I did have to put the charger on it once over the winter because I failed to start it for awhile but other than that it's been just fine.
I don't think you'll find a battery tender for an 8V either
what I needed to know , thanks, and steve, sorry if i caused any extra stress in you life over the question.
No stress, just my smartypants comment about this being a much-chewed-over subject, like water pumps and oil.
I have used 8 volt batteries in 2 of my cars and the others use 6. They cost exactly the same at my NAPA dealer and they stock 1 with each battery order they place. They can be charged (at albeit a slower rate) with a 6 volt charger just fine. Only 1 car has a generator and I have not adjusted the charging rate. The install date of one of my 8 volt batteries id 2008 and it is perfectly serviceable. Nothing is wrong with my electrical systems in any case but I like the idea of brighter lights, faster cranking speed, and the extra 2 volts for the same price.
