It's market is dying off. The Mercury brand is just a rebadged Ford which costs more. The Mercury Milan is nothing more than a rebadged Ford Fusion. Mercury Mariner is a Ford Escape. Mercury Mountaineer is a Ford Explorer, and the Grand Marquis is a Ford Crown Victoria. In the past the Mercury was a totally different car but in the last few decades that has not been true. Therefore Ford can save money by eliminated a duplicate brand of Ford cars it already builds.
A car battery would keep dying because inversely, the lesser the battery is used, the dying process continues. The more the battery is used, the lesser the dying process. But the dying commences and continues , the moment the car engine is not used. Thus, as often as the car is being used, the dying "resumes" the moment tne engine stops. And the faster it is used again, the slower the dying process.EVerytime the car engine is used, the battery recharges, thus life is given back to the battery. Once the engine stops, the dying resumes. This is why the car battery keeps on dying (everytime the car engine is not being used)
