The Interstate Battery web sites indicate the B series mostly use a group 51 battery, which is 9 3/4 long and 5" wide.
The battery in the B7001 measures 9 x 4 3/4 x 9, which does not look right.
However, the battery has the code 50B24l stamped on it, and I picked this up from another thread...
"If that is a B7100 then I think the Kubota part number is 66704-55430 a cross reference battery number should be 50B24L"
I don't see any battery in the chart that is as small as the one in there now.
The B7100 is listed as a group 51 battery, so I am a bit confused.
If that Kubota number is correct, then the rest is easy. Can anyone help here?
