What battery is being used in the 85-86 Turbo Coupes since Motorcraft is no longer producing the correct one.

Just bought a Motorcraft battery in Nov. for $140.  Part No. BXT 65 850.  It's about the same size as the original for an automatic which I believe is a little larger physically
than the one for a 5 speed.

I have been using group 65N batteries in both my 88 TC and 86 Tbird 5.0 for years. I use Wally World Everstart MAXX 65N 1000 CCA batteries. Usually get 5 to 7 years out of them. Just replaced the batt in my 86 for $95.

I didn't try that hard to find a group 56. I did try to fit a 26R per suggestion of the battery shop but abandoned that idea because my pristine OE hold down would have to be modified to fit.

Ended up going with a group 55. It's about 1.5 inches narrower than the 56 so I have more room at the end of the radiator now. Only gave up 50 amps, had 590 cca on the wally world 56 and now 540 cca on a Duracell Ultra 55.

Looking at my battery tray I don't see how I could fit anything wider than the 56 like the 65N. 26R is too wide.

I don't really know why I would need a bigger battery since it just starts and runs the ignition and radio. I dont have any power options and my big stereo is years since removed...
