6 volt or 12 volt...and other battery issues
Looks like I will have to replace my 12 volt batteries. When I do, wondering if I should go with 2-6 volts in series or 2-12 volts in parallel? If I go 6 volt, the only disadvantage (other than cost), is if one goes bad, then I only have 6 volts available, whereas if I stay with 12 volt, at least I'd have full (albeit reduced longevity) functionality.
So, what are the thoughts on this subject from others. How much extra longevity can I expect if I go 2-6 volts over 2-12 volts.
Whether I go with 6 or 12 volt, what should I look for in a battery? Deep cycle? CCA? Specific brand to go for (or avoid)? No maintenance, or gel cell, or regular maintenance?
I think I'll put some other general battery questions in a separate thread, so that will do for the purchasing issues. Thanks.
