rack size for batteries

Are the rack they use for batteries in Rv's standard sizes? Here is my issue. I bought an 06 Gulfstream Ultra. It has a rack to hold two deep cell batteries (but it only has one 12V at the moment). In reading the forums, I might want to purchase 2, 6V golf cart batteries, however, I am not sure they will fit. I measure my rack and it is 14 1/4 inches. Most golf cart batteries I am seeing on line have a listed measurement of 7.13 inches.

So my question--can my rack handle two of this six volts? How tight can these things be? Are most racks designed to handle these standard battery sizes? Thanks for any help

    Here is a TROJAN T105 spec sheet which shows the case dimensions



    Usually the kicker with the 6V GC2 batteries is the height - They are alot taller than a standard battery...

    X2 on marking cables. It is so easy to get them reversed. If that happens then you will looking for fuses to replace. Use TAPE and mark each lead a "+" or a "-" depending which battery terminal they come from...

    Also don't forget the 6V golf cart batteries have to be conneced in series to get 12VDC out of them


    just my thoughts

    Let me cut to the chase scene.

    The TOP and BOTTOM measurement physically is not the same on the battery.

    Both dimensions are important if you want to have a battery bank.

    My gut instinct tells me that you have nothing to worry about; yet I have seen even more common things not work in particular applications.

    Shove as much amperage as you can get in the space available. 2 6V, 2 grp 24s, 2 grp 27s, 2 grp 31s, a single 4D, a single 8D. Whatever uses the space best.

    Skipnchar has some good advice. Use some spacers. You can make your own with plastic cut up PVC pipe or whatever you find at the hardware store. Use your imagination. I'll add you can also use a nylon tie down strap to to hold down the battery box.

    For my friend, I simply cut off his existing metal battery rack and welded on a custom sized one to his specific needs. Simple angle iron is your friend. You can find a welder to do that very simple and effective mod, if need be.

    I'd do it for you for a beer and pizza, but you and I live at two different coast lines.

    The foot print of a Trojan T 105 (the most popular 6 volt battery) is exactly the same as a standard group 24 battery (12 volt). It is about 2" taller however. It's tremendous POWER and staying power are achieved with plastic spacers between the SOLID lead plates as opposed to cardboard spacers between waffle plates in most Deep Cycle batteries.
    Good luck / Skip
