Do chickens have large talons
As long as the amp-hour doesn't exceed the sum of the two originals, it won't make a difference. But one advantage of having two batteries is that of one seems to be draining the other, you can disconnect the parasitic one and run on just one battery for a while (As long as it's not too cold out)I've not been real impressed with my NAPA batteries. For my gasser I bought one from Autozone - I think it was the DL Gold - and it did well. I don't know how many of you are Consumer Reports readers but the list certain DuraLast Gold batteries as good buys. If I have the money when the time comes about I think I'm going to go with a couple of the sears diehards next time though.
As for the one big battery, that might be great for starting but I would venture to guess you may start burning up alternators. Keep in mind that the beast will require charging and the standard alternator may not beable to do the job real well.
Just my 2 cents...
