This automotive maintenance tutorial was specifically written to assist owners of the second generation 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 and 2021 Ford EcoSport compact SUV equipped with the EcoBoost turbocharged 1.0 liter inline three cylinder engine in changing a weak or dead 12 volt car battery.

Owners of other Ford or Lincoln vehicles such as the Fiesta, B-Max, Escape, Edge, Bronco Sport, Explorer, Expedition, Transit, Focus, Mondeo, S-Max, Puma, Kuga, Endura, Everest, Ka, Figo, Endeavour, Aviator, Corsair, Nautilus and Navigator may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) 12V automotive battery part number in this 2020 EcoSport was FoMoCo BAGM-48H6-760 (G519S). It is an AGM (absorbed glass mat) battery with 760 CCA (cold cranking amps).

The battery "Group Size" is H6 (also known as 48).

Two compatible replacement 12V batteries with their part numbers are as follows: ACDelco 48AGM and EverStart AGM H6 (at Walmart).

The tools needed to complete this procedure include a 10mm socket with a 1/4" drive ratchet or a 10mm wrench and possibly also a plastic pop rivet removal tool.

Please proceed with caution and at your own risk!

The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The 12V automotive battery is located right behind the engine air filter housing, to the left of the fuse box and in front of the windshield.

Warning: Avoid touching both the negative and positive terminals at the same time to prevent from being electrocuted.

First, loosen the "-" negative terminal by turning the nut in the counterclockwise direction with the 10mm socket and a 1/4" drive ratchet.

Cover & Tuck Away
Carefully pull the negative terminal off the "-" battery post.

Push in the release tab on the small electrical connector attached to the negative terminal before sliding it straight out of its socket.

Cover the negative terminal with a small towel and tuck it away behind the battery to help prevent accidental electrical contact.

There are three silver metal nuts on the top of the black hold down bar that secure it in place.

Loosen the nut on the left side of the bracket by turning it in the counterclockwise direction with the 10mm socket and a 1/4" drive ratchet.

You may need to use a deep well 10mm socket.

Lift Out Old Battery
In order to detach the positive terminal and the power distribution board, you may need to remove the cover on the engine air filter housing.

The air box cover is held in place by two metal latches.

Carefully lift the positive terminal and the power distribution board off the top of the old battery.

Raise the two plastic handles on the top of the old battery.

Carefully lift the old battery off the tray and out of the engine bay.

Gently rest the old battery on the ground. Try to avoid dropping or tipping over the old battery to prevent from having acid leak out.

Be sure to take the old battery with you to the auto parts store or Walmart so you can avoid paying a "core", "disposal" or "recycling" charge.

Lower In New Battery

Push On Positive Terminal
Clean off any debris, dirt or dust from the plastic tray so that the new battery will rest evenly on it.

If you can wait a few days for delivery, the ACDelco 48AGM battery has excellent reviews on Amazon.

Orientate the new battery with the negative post at the rear of the engine bay and the positive post closer to the front of the vehicle.

Carefully lower the new battery down into the engine bay and on top of the plastic tray.

If you've had a problem with corrosion (white, blue or green powder) building up on the terminals or posts, consider installing some felt anti-corrosion washers over the battery posts. They are very cheap insurance against having to replace corroded terminals or cables.

Lower the positive terminal and the power distribution board over the "+" positive battery post.

Tighten the nut for the positive terminal by turning it in the clockwise direction with the 10mm socket and a 1/4" drive ratchet until it is snug.

Try to avoid over tightening the terminal nut to prevent from cracking the battery post.

Spin on the three nuts a few turns in the clockwise direction to help prevent them from becoming cross threaded.

Reminder - The larger nut goes on the right rear of the hold down bracket by the suspension tower.

Testing New 12V Battery
Re-attach the white plastic retainer for the wire loom to the threaded bar on the hold down bracket.

Double check your work to make sure the connections are secure and the battery can't be moved, rocked or slid around.

If the battery can be moved, tighten the three nuts on the hold down bar an extra turn or two.

To test the new battery, start the engine.

If you suspect that your alternator is weak or might be failing, use a digital multimeter tool to check the voltage when the engine is running.

If the alternator is working properly, the voltage on the battery terminals should be about 13V to just over 14V when the engine is running. If the engine is switched off, the new battery should read at least 12 volts.

Be sure to write down the battery change in your SUV's service records.
