Watt Hour Capacity of 27 Deep Cycle battery
I have a battery with this information on the label: Interstate SMR-27, 600CCA, 750 MCA, Deep Cycle. I haven’t found the right information on Interstate’s website. I found this on some of the ...

96 amps times 12 volts at the 20 hour rate.
Let's see... 960 + 192 = 1152 watt hours at the 20 hour rate
You can safely use 1/2 of that, LESS if you use it faster
NOTE: Normally I use round the G-27 to 95 amp hours, which is how I remember it, Thank you for posting the battery's specs so I can do it exact.
IN a DC circuit, AMPS times VOLTS really does equal watts. (not true in AC).
NOTE: I short cutted a bit.. The full calc
C=Capacity c-Sub(20) is the amp hour capacity at the 20 hour rate
A=Amps
V=Volts
c-Sub(20)/20 times volts times 20 = W-Sub(20)
(Sub means subscript, I can't do that here).
As you can see the 20's cancel out so I did not bother with them in the shortcut.
And yes I majored in math with a certificate (Kind of a 2nd major) in electronics.
