If you go into a FLAPS that sells Interstate Batteries, you'll
probably be directed to the MTP-91, if you try to buy a Group 41
battery.

The MTP-91, as you might gather is a Group 91 battery. It's now an 85
month battery (!). Interstate does a good job honoring their warranty
no matter where you are, and Interstate Batteries are carried by a
heckuva a lot of FLAPS.
