The battery I bought is a MTD-91/T6 to replace my MTD-91. The MTD-91 is no longer made but you may be able to find old stock. Also I am now told by Interstate that MTD-91 has been replaced with the MTD-48/6H.

The MTD-91/T6 does not list CA or CCA. Nor does the website.

Anyway, I drove the car nearly 100 miles tonight and no trouble. Hopefully the crank sensor was the problem.

Thanks for the replies. James
