FordFusion00 Posted March 16, 2021 Share Posted March 16, 2021 (edited) 2018 Ford Fusion Titanium Hybrid, 65k miles Current battery Original Ford Motorcraft BXT-90T5-590 Cold cranking amps: 590 Batteries I am interested in Odyssey Performance Series ODP-AGM48 H6 L3 Cold cranking amps: 720 Warranty: 36-month free replacement ~$268ish - expensive !! Motorcraft BAGM-48H6-760 Cold cranking amps: 760 Warranty: 36-month free replacement, limited warranty of 100-months & unlimited mileage ~$183ish - not so bad !! Would love an Optima battery, but they don't make one for my car. Questions Would an AMG be a big upgrade given that my current battery has 65k miles on it and a relatively small CCA of 590? Why is the Motorcraft so much cheaper than the Odyssey? Is the Odyssey worth it? Best place to purchase? Normally, I'd purchase a battery locally from an auto parts store. They handle any warranty issues. What do I do if I have a battery issue under warranty? For the Motorcraft battery, can I just go to any Ford dealership?

Same answer as over on the Ford Fusion Club. Here is my opinion: Purchase the Motorcraft battery. There are usually coupons available on the Ford Owners website for the top of the line, Motorcraft Tested Tough Max battery @ ~$129. If you have warranty issues, you bring it back to a Ford or Lincoln Dealership. I am sure others will jump in with their own opinions and recommendations. Let us know how you make out and good luck. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted March 17, 2021 Share Posted March 17, 2021 I agree with bbf2530. If you need a replacement battery, just stick with the OE recommendation. There are 2 things going on here. First, the 12V battery in your FFH is a BCI Group 90 (T5). Dimensions for Group 90 are L: 9.5", W:6.9". The other 2 (AGM) batteries you referenced are Group 48 (H6) batteries. Dimensions of that group are L: 12.1" and W: 6.9". While the widths are the same for both groups, the H6 batteries are 2½ inches longer than the battery that's OE in your car. Therefore, you'll have a fitment issue, as the Group 48 battery will not fit the tray in the Hybrid without some kind of modification. Are you prepared to hack up your battery mounting tray? On a sidenote, since the 12V battery in the Hybrid is trunk-mounted, it has a vent tube. While AGM batteries are not known to emit hydrogen gas, as lead-acid batteries do, they don't normally require venting in enclosed spaces. That's a chance you'd have to take, as the AGM batteries have no vent provision built in. Second, why do you feel that you need over 700 CCA in a Hybrid. The 12V battery in the Hybrid is not used to start the ICE. That function is performed by the HVB. True, you need a healthy 12V battery for proper operation of the Hybrid, CCA isn't going to help with that. Hence, Ford puts the smaller 12V battery in the Hybrid. OTOH, Ford specifies the AGM, 790 CCA battery as OE for its gasoline models that employ idle stop/start to address the higher electrical loads placed on the battery by the frequent stop/start cycles those cars will be subject to in normal use. You don't need 760 CCA in a Hybrid. It's capacity that will never be used. 0 Quote Link to comment Share on other sites More sharing options...
