TonyHzNV Report post Posted February 6, 2015 While doing a little research to verify the "correct new number" for the 12V battery, I discovered some interesting things. First, on fordparts.com I discovered that there are actually 2 different batteries listed for my 2014 Fusion Hybrid: BXT-99RT4 (listed in the 2nd printing of the 2014 OM as BXT-99RT4-390) and BXT-99RT4-A. The former (BXT-99RT4) is applicable to: 2.0L 122 CID 4 Cyl Electric/Gas and the latter (BXT-99RT4-A) applicable to: 2.0 4V Dual Overhead Cam PFI Gas/Electric (See attached FordPartsBatteryResults.pdf below) Huh? There are two different engines in the hybrids? THAT got my curiosity up, so I checked 2013 and 2015 as well and both batteries were listed for each model year with the same applications. So, I started a chat session (see attached) with fordparts.com to try to determine the correct battery and also to verify that there are 2 different engines. As you will see by reading the chat transcript, I was told that BXT-99RT4-A is the correct part number for my VIN because I have the 4 valve per cylinder engine per the "build sheet". When I asked which Fusion Hybrid the BXT-99RT4 was for, I was told "the one with 2 valves per cylinder". So, there are two different hybrid engines? I was told yes there are. Is it possible that the Energi has a different 2.0L engine than the Hybrid? I don't know. How about you? I got the brilliant idea to call the Ford Customer Service line and ask these same questions. I really didn't get any help there. I was referred to my dealer who would know more about this. Really? Next I called the Team Ford-Lincoln (my closest dealer) parts department and asked them too. I was told that the "-A" part number didn't even come up in their computer and that all they stock is the BXT-99RT4 for $119.95. They had no idea about a different battery OR different engines. Ihave attached a copy of the page showing these two batteries/applications, and a copy of my shopping cart where I successfully placed one of each battery so you can see you really can order them (through fordparts for pickup at your dealer). Maybe somebody out there among you has some knowledge of the two different batteries and/or the two different engines? Waldo, you listening? Maybe this is a another case for Meagan.HELP!!!! :)12V Battery Chat Transcript.pdfFordPartsBatteryResults.pdfFordPartsCart001.pdf 1 GrySql reacted to this Quote Share this post Link to post Share on other sites
GrySql Report post Posted February 6, 2015 From the Manual:2013 Ford Fusion Hybrid Atkinson Engine OverviewThe 2.0L 4-cylinder engine has the following features:Dual overhead camshaftsFour valves per cylinderComposite intake manifoldAluminum cylinder headAluminum cylinder blockThe 2.0L engine is a 4 valve-per-cylinder, dual overhead camshaft engine. The engine uses a coil-on-plug ignition system. The cylinder block is made of aluminum and the bearing caps are integrated into the ladder assembly. An aluminum oil pan bolts to the bottom of the lower cylinder block and to the transmission to provide greater strength. The camshafts are mounted in the cylinder heads and act against valve tappets to open and close the valves. The camshafts are driven off the front of the cylinder head by one timing chain. The chain is driven by a sprocket that is located on the crankshaft. The piston assembly is an aluminum piston with a cast iron connecting rod. 2 Hybrider and hybridbear reacted to this Quote Share this post Link to post Share on other sites

mrobinso8 Report post Posted February 13, 2015 My dealer just replaced the 12 volt in my car for the 4th or 5th time. Had the bs message instantly when the car was turned off. Prior to that the Garmin unit would occasionally stay on along with the seatbelt warning light. Took data from Forum on the Garmin shutdown (I have built in Nav but use Garmin on trips since it is easier to use) to help tech analysis of issue. Replaced Air Bag Sensor assembly, RCM, and installed battery BXT 99RT4. Oh for a reliable car. Quote Share this post Link to post Share on other sites

Still waiting to find out what the difference is with BXT-99RT4A which is supposedly the correct battery for my VIN. Quote Share this post Link to post Share on other sites
mrobinso8 Report post Posted February 14, 2015 The last battery was the old version. The service advisor put in the new version based upon the print I gave from this forum as to the RT4 I believe. All I really know is that they did the replacement under warranty as usual. Time will tell if this helps but hopefully I can replace the car before it dies again. Problem being finding what I want without having to get stuff I do not want in a "Package". Quote Share this post Link to post Share on other sites

Can you possibly find out what the difference is between the BXT-99RT4 & the BXT-99RT4-A? Is there a difference in size/specs? We would all be interested to know since the BXT-99RT4 seems to be getting installed in some of our cars. There hasn't been any mention of the RT4-A. Thanks again. 1 GrySql reacted to this Quote Share this post Link to post Share on other sites

MeaganOK, Meagan, thank you for following up on that. I do find it strange however, that my local dealer, Team Ford-Lincoln, told me that the "-A" part number didn't even come up in his computer. Must be a pretty new number, huh? Thanks again for your help. At least we know now that either number is OK and there's no difference. Have a great day! :) 1 GrySql reacted to this Quote Share this post Link to post Share on other sites
