If you convert the 200 minutes to hours and X 25 you get 83 AH which is about right for a cranking battery. A deep cycle battery that weighs that much would have around 125 AH.
I replaced my 10 year old Interstate 31s last summer as Interstate made me an offer I could not refuse at the FMCA rally in OR... I got to keep them. I put them in a 24V machine I own and they are still going strong. I did find the caps under the hard plastic top of these "maintenance free" and would add a small amount of water every two years. Taking the caps off and checking the Specific Gravity of each cell will tell you a lot about them.
I have noticed I have alot of reserve power after camping last weekend.
I plugged motor home in after getting back ( 5 days later )I unhooked it today and let it sit for about 3-4 hours and tested voltage it checks 13.41 volts no charging going on . I did test when it was plugged in 1 hour before I unplugged it and it was trickle charging at 13.71 volts . the day I got back from camping it was charging 14.71 volts
from the 110v . So everything with charger seem to be working good . far as I know . Did find issue with cranking battery has a slow dis charge even with everything off . That will be next project :)
