Step-by-Step Battery Replacement Procedure
Replacing the 12-volt battery on the 2017 Lincoln MKZ requires standard hand tools and adherence to electrical safety protocols:
- Step 1 (Safety Isolation): Turn off the ignition, set the parking brake, and remove the key fob. Wear ANSI-approved safety glasses and insulated work gloves.
- Step 2 (Negative Disconnect First): Use a 10mm wrench to loosen the Negative (Black / Minus) terminal clamp nut. Twist and lift the clamp clear of the terminal post to break chassis ground.
- Step 3 (Positive Disconnect Second): Loosen the Positive (Red / Plus) terminal clamp nut and secure the cable safely aside.
- Step 4 (Hold-Down Bracket Removal): Unbolt the 10mm base clamp hold-down bracket and lift the old battery vertically out of the vehicle tray.
- Step 5 (Tray Cleaning & Seating): Scrape corrosive acid deposits from the tray using a wire brush. Lower the new Group 90 (T5) / Group 48 battery into place.
- Step 6 (Torque & Reconnection): Secure the hold-down clamp to 3.5 to 4.5 ft-lbs (40 to 54 in-lbs / 5 to 6 Nm). Reconnect the Positive (+) terminal first, then the Negative (-) terminal last.
Frequently Asked Questions
What battery size does a 2017 Lincoln MKZ take?
The 2017 Lincoln MKZ requires a BCI Group 90 (T5) / Group 48 12-volt battery with a minimum rating of 590 Cold Cranking Amps (CCA).
Does this vehicle require an AGM or standard flooded battery?
Standard Flooded / AGM. If equipped with engine start-stop technology, an AGM battery is mandatory to support continuous micro-cycling.
Why must the negative battery terminal be disconnected first?
Disconnecting the negative cable first eliminates the danger of an electrical short circuit if a metal tool accidentally touches the vehicle metal chassis while loosening the terminal.
How long does a 12V car battery last?
Most automotive batteries last between 3 to 5 years depending on climate, daily driving distance, and alternator charging performance. High ambient heat accelerates grid corrosion.
