MD Mondeo Ecoboost signs of failing battery

[NX74205]

I also had my battery replaced recently, but I chose to go with an OEM one. My car's symptoms were:

- 'Easy Access' driver's seat won't slide forward after starting the car;
- 'Active City Stop' failure;
- Parking sensors sound strange;
- Passenger side mirror won't auto unfold when unlocking the car.

Had almost four years out of the OEM battery. Hopefully this one will last at least as long.
