Note the battery date 092607. 09/26/2007............. If you go to Ford and buy a battery right now, the listed replacement part number is also BXT 96 R, but the labeling has changed.

How did you upload your picture's? john I uploaded the pictures to a host site, postimages.org and then linked them to this forum thread. Does your BXT-40R have a 2006 or 2007 date on the label? When I owned one of each of the Cobra R's, 1993, 1995 and 2000 I found that the 1993 Cobra R had a couple of different batteries that were installed on the Ford assy. line, so I know this does happen.

R Ford used two batteries in 07-08 the one you show is a BXE 96 R which is smaller in size & capacity The BXT 40 R is large in size & more crank amps. The cover & case that it fits in your car of coarse is larger so be careful when changing your battery to an OEM as the large one won`t fit BXT 96 R 550 ca crank amps at 32 F 625 Length 8.97" Width 6.30" Height 6.88 " Weight 32 lbs BXT 40-R 590 crank amps at 32 F 735 ca Length 10.90" Width 6.42" Height 6.88" Weight 37 lbs. The only reason Ford might have used the RXT 40 battery in cars going to colder countries for the extra cranking amps just a guess though. Hope this helps.

johncola99 Posted August 29, 2018 Author Report Share Posted August 29, 2018 Hey guys , thanks for responding. My original battery has the charger cable on it. The other is a replacement for ford dealer. Original has a YN in front of part number, the other doesn't. Orig has the handle holders on side near top, the other doesn't. The original has a date code of 7B18B41D.I think feb of 07. Both dimension's are the same. The bxt-96 is smaller in dimension's. I really would like to find exact battery if it is out there. thanks Quote Link to comment Share on other sites More sharing options...

Robert M Posted August 30, 2018 Report Share Posted August 30, 2018 (edited) Mine also had (and still has) a heat shield blanket that is fitted to the BXT-96R case, it sounds like this same heat shield blanket will not fit the BXT-40R if it is a larger case? I would guess that the larger the case and the closer to the right side cylinder head/valve cover heat, the more need to shield the battery from that heat? or maybe that is why Ford down sized the battery case size? Too much heat in that corner of the engine compartment for battery longevity? I live in Florida, but my car was originally sold to me from a Northeastern Ford dealership, so I can't say that cold weather regions got the bigger battery because my car came from that region and did not come with that battery. As it relates to the BXT-40R, have you called your local Ford dealership parts dept. and asked about that part number, and if they can get one?

If so, that would be the way to go, if not, then the current replacement for that application will be the only option from Motorcraft. My thought was......just because the 40 is not listed for the GT500 application now doesn't mean that it is not still available for another application......

Robert M Posted August 31, 2018 Report Share Posted August 31, 2018 I'm on with my local Ford parts dept. right now, he has 2 BXT-40R's in stock. He is looking through the original Ford applications beginning in 1995 thru current, Contour, Mystic, Cougar, Escape........all the way to now Transit. He says that there are no Mustang applications listed in the Ford documentation for the 40 series and that the current BXT-96R has the exact same 590 rating as the 40. I had not paid much attention, but apparently the BXT-96R has been upgraded over the years from it's original 500 as shown in my pictures to a current 590. I have a Shelby cover on my battery currently, so I can not verify the label information. R Quote Link to comment Share on other sites More sharing options...

Nice information! Since the 40 series is mentioned in the owners manual for a 2007, I would buy that battery from my Ford dealership if that was original to my 2007, and call it a day.

mhr1961 Posted September 2, 2018 Report Share Posted September 2, 2018 well, The variables have been pointed out which may have resulted in a slightly different battery being substituted at times. If a BTX40R is what you said was in it originally, and the supplement says BTX40R, then I would say go ahead and put the BTX40R in and call it day Quote Link to comment Share on other sites More sharing options...
William Rodgers Posted September 2, 2018 Report Share Posted September 2, 2018 I just replaced my 2nd battery, went with an Interstate from Costco, best out there for the money.

Robert M Posted September 2, 2018 Report Share Posted September 2, 2018 (edited) As I previously mentioned, I was able to slip my original battery blanket/heat shield onto the replacement Motorcraft battery so the dimensions are the same and one other point of interest..........That Shelby battery box that is shown in one of my posts above.......that cover sits directly on top of the battery and attaches with a bolt and "T" bracket with the oem wedge block to secure this battery in place. If the replacement battery were taller, the "T" bracket would not attach and if it were a shorter replacement, there would be space between the cover and the battery top. One other thing as it relates to this subject..........The battery blanket that is original to my car, with original Ford part number has been changed by Ford at some point in production. The replacement has a different part number and there were a couple of differences. Since my original blanket was in perfect condition, I put it away and installed a new replacement blanket instead. Both blankets were the same size and fit, but there were some differences at the bottom in the mounting area, and the part number. Here is my original 2008 GT500 heat blanket and the replacement Ford part number bag below.............My Ford parts friend said that the engineering number on my original blanket crossed to another part number and that part number had gone obsolete and been superseded to the part number shown on the Ford bag. The Shelby battery box/cover that I previously posted a picture of slides snuggly (but not too snug) over the battery blanket after it is installed on the BXT-96R battery.

I must admit, those batteries were on Battery Tenders when the cars were in the garage, so that may have helped the battery longevity.

KOBRA2848 Posted September 13, 2018 Report Share Posted September 13, 2018 Either battery will fit your car. After you remove the battery you will see some plastic tabs that center the battery side to side that are removable in case you put the 40 R instead of the 96 R. If you want to reuse your existing battery blanket you would have to keep the same battery size. Motorcraft and Interstate batteries come from the same manufacturing facility and on the 96 R size the Interstate battery is the same case color as the original and not green like most of there batteries.
