Hybrid underhood battery terminals -- photos & video

[Moorparkmark]

There been many posts regarding using the under hood battery terminals for tricklecharging and jumpstarting, etc.

I took a couple pictures and a short video to aid those who may be looking for these two rascals for the first time. Hope this helps.

The video demonstrates how to open the positive terminal cap.

note: just in case it’s not self-explanatory the connector with the black X over it is one that should not be used for anything other than looking at it wondering what it is.

Thanks for that. The manual was zero help and it was difficult to see the red cap.

Thanks!

Nice tip, I assume the red is positive, but I don"t see a negative terminal. To charge that
battery, one needs to hook up a positive to a positive, and a negative to a negative, right? Or is it different on the hybrid battery? Thank you.

The negative terminal, or ground in this case is the bolt like object with the black circle around it. Good question

Thanks for the info, I wasn't looking for it at this time but now I know for future reference.

It appears the one you thought was a negative point is not according to this post by another member in a similar thread.

After charging 100's (1000's?) of batteries in my life by attaching the black clamp to the negative terminal I finally started to use a grounded bolt after getting my Maverick. I've never had a spark blow up a battery but thought I'd change to a better practice. With the battery under the seat Ford just made it easy to find a clamping point by using a stud at that location.
I can't remember from the manual - did they provide a stud on the non-nybrid?

RTFM the one in the picture is the point for underhood access. The terminals on the battery can alway be used as well but preset a risk of spark and explosion, albeit rare it does occur.

Never noticed the final warning in the manual instructions - good to know you MUST remember to take headlights OFF auto-mode if doing this at night.
I guess if anyone had any experience with this - old habit was hopefully to disable ALL electronics possible when jump starting anyway. But auto-headlights and new habits could cause problem.

Not really sure why #3 under Starting matters since the HVB takes over charging the 12v as soon as Key On is hit.

JUMP STARTING THE VEHICLE - HYBRID ELECTRIC VEHICLE (HEV)

Connecting the Jumper Cables

WARNING: Do not connect the negative jumper cable to any other part of your vehicle. Use the ground point.

Note: Your vehicle has a 12-volt battery that has two pins accessible from under the hood. Your vehicle can be jumped the same way conventional vehicles can by using these pins. The following illustration shows the two connector pins used for jump starting your vehicle.

A Positive (+) pin. B Negative (-) pin.

Note: If you are using a jump pack or booster box, follow the manufacturer's instructions.

1. Pull the red rubber boot backward. Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.

1. Connect the other end of the positive (+) jumper cable to the positive (+) terminal of the booster vehicle battery.

1. Connect the negative (-) jumper cable to the negative (-) terminal of the booster vehicle battery.

1. Make the final connection of the negative (-) jumper cable to an exposed metal part of the disabled vehicle's engine, as shown in the following illustration, away from the battery and fuel injection system, or connect the negative (-) jumper cable to a ground connection point if available.

Starting the Engine

1. Start the engine of the booster vehicle and moderately rev the engine, or gently press the accelerator to keep the engine speed between 2000 and 3000 RPM, as shown in your tachometer.

1. Start the engine of the disabled vehicle.

1. Once you start the disabled vehicle, run both vehicle engines for an additional three minutes before disconnecting the jumper cables.

Removing the Jumper Cables
Remove the jumper cables in the reverse order that they were connected.
Note: Do not switch the headlamps on when disconnecting the cables. The peak voltage could blow the bulbs.

What thread so they can be set straight before spreading more mis-info.

Good point about using a secure ground rather than the negative post on a battery for charging (jumping). When I first got my license my father showed me the correct way to connect jumper cables. The probability of causing a spark and explosion is rare, but finding a proper ground only takes a second or two, so I opt for the proper procedure.

It's funny how things that we've done for 50 years have changed and aren't necessarily the correct way to do them now. I'll opt for the safer way now.

Yep. To anyone looking at this - this is for the NON-Hybrid.
Eh - same spot though.

It's like how I learned to disconnect the negative terminal first when removing a battery. Had an 60 VW with the battery under the back seat. Put my wrench on the positive terminal nut and rotated it till it hit the seat frame. Lots of sparks and lesson learned!
