My father has a 2012 Fusion Hybrid. He is currently in assisted living now, and is unlikely to be driving again. The car has been sitting in the garage at the house. I have occasionally driven it, but it recently sat too long and the 12V battery died. I checked, and he had written a date on it, sometime in 2018. So it's due for a replacement anyways. I did try charging it up, but didn't have too much time to really fully charge it. After about 2-3 hours, it did power up, but gave a bunch of weird errors, and then the display went blank. The engine itself never started.
The battery in there now is a Motorcraft BXT-67R. I get mixed part numbers if I search online for what belongs in the car. Any good ideas on a battery? I do see the same battery for around $135 or so at various places nearby.
Also, any good trickle chargers or similar? The car will probably be eventually sold, but would like to keep the battery topped up. Also, this does not have the updated software or battery age fakeout, so the hybrid feature is barely more than start-stop.
