I have four golf cart batteries purchased at Sam's place for my house batteries.
They are 107 minutes at 75 amps each. How does this translate to amp hours?

I will second that,, Most of those Golf Car GC-2's are 220+/-10 with Sams and Costco being -10 so his estimate is perfect.

Just so you know,  Most all batteries EXCEPT OPTIMA of the same size are xx+/-10%

Group 25 75 AH
Group 27 and 29 just under and over 100
Group 31 130
and GC-2 220, (NOTE you need two GC-2's and you wire in series you add VOLTAGE not AH)

You have a very nice set of batteries there. Exactly what I would recommend.
 
The Sam's Club Duracell GC2 golf car battery has a 20-hour rating of 215 amp-hours.

There is also an EGC2 (taller, extended capacity) that is rated for 230AH (20 hour rate) and 120 minutes at the 75A rate.

The "20 hour rate" is the universal standard used to compare batteries of different makes and sizes.
