That depends on how the batteries were wired, for what voltage. If they were to provide a 6 volt source, then yes, but not for very long as the 12 volts would burn the motors out very quickly. If they were wired to provide for 18 volts then yes, but it won't run very fast because of the low voltage.
A cart that has batteries connected in series with one plus and one minus cables may have three 12V batteries connected with two jumpers, instead of twice as many 6V batteries with five jumpers.
Sort of: you would need about 80 motorcycle batteries 10 to 20 Car batteries Or six to 8 of the correct golf cart batteries.
no
no, but they can be rebuilt.
Anecdotal opinion says golf cart batteries will last three years under normal, everyday, use.

Spare golf cart batteries can be bought from a number of specialist golf hardware providers both online and in a specialist golf store. You can also purchase them from specific golf cart dealers.
It depends on the ratings of the batteries and how they are connected.
No!
Depends on the amperage of the batteries you are using. Both setups will give you 36 volts, but you will normally have a longer run time with six 6 volt batteries in series than three 12 volt batteries. That is why golf carts use 6 volt instead of 12 volt batteries.
Golf cart batteries can be purchased in your local area at designated retailers, ordered from the manufacturer by telephone, or purchased online at one of the dozens of online retailers who carry your specific Golf Cart Battery brand.
