either it is my fault for running 15w-40 rotella oil in the M-37, but at below 15 degrees, it don't have enough umph to turn the engine over and start the M-37.

I gave both batteries a slow charge last month, but they are about 6 or 8 years old, depending on the battery. They are old, diehard silvers.

I know with the giant underseat battery box, I have many choices. The original hold downs are long gone, so I am limited only in total battery box area.

What are the favorite sizes folks are using?

The truck has been used here and there all winter, most recently about 10 days ago when we used it to unstick the 68 utiline and the motorcycle trailer from frozen muck. It has a busy spring coming up with land clearing for the new shop. It is the only thing that can operate on the muddy, hilly terrain.
