Upgrading Batteries

If you have 2 6 volt coach batteries installed in series can you change to 1 12 volt battery. Also, same scenario with the chassis batteries. I need to replace the batteries on a recently purchased 1992 Coachmen Royal 360RD. What are good dependable batteries, also is a battery minder a good investment.

Thank you all for your help

I am not a battery guru, so forgive my lack of battery terminology, think technically you could replace 2-6v with 1-12v, however the 6v batteries have twice the run time of the 12v, so you are really doing yourself a disservice by downgrading to 12v.

Have read nothing but good things about the Costco batteries, and that is what I have on my coach, and the bonus is they are very well priced, paid $84 each for my 6v batteries.

Am sure someone a lot smarter than me will give you the real skinny on batteries.

Good Luck!

Upgrading Batteries

2 golf cart batteries of the GC2 variety have a capacity of 220 amp hours when wired in series to produce 12 volts. Not many 12 volt batteries have that much capacity.... It takes lead to make capacity.....so if the batteries don't weight the same, they aren't the same !
