How to add water to the battery?

[rob4092xx]

I have a 2018 Expedition and the battery seems to be sealed as it has stickers over the fill caps. Does this mean it is a sealed battery and I am not to add water? Thanks!

It is a maintenance free battery, hook it up and forget it - until it dies.

When it dies can it be replaced with an Interstate battery from Costco or do I have to go to the dealer and get the same battery as now?

As long as it has the same amp ratings for cranking etc then you can get any male you want. But the auto start on our cars places a massive strain on the battery so thinking you can save a few bucks on a budget brand will be a false economy

Just make sure what ever you get is maintenance free. That way you will avoid all the corrosion issues that came with the old style wet cell battery that you ad water to.

It is an AGM absorbed glass mat battery. Replace as such

They started using AGMs for 2018????

That and they changed the size. It's a group 94 reversed terminal now. Looks like a full sized Mercedes battery, grp 49. Guess they need the extra oomph for the constant use of starter at stop lights.

Where do you get one of these? How long do they last?

I buy my batteries at NAPA I get their Legend AGMs.
I had my wife’s wet cell battery explode in her Highlander. The battery cable terminals were fused to the battery posts. I had to soak them for 3 days to get unfused. Cleaning the engine bay was a nightmare too.
No more wet cells for this guy ever.
I did not know Motorcraft was making AGMs. When it is time for a new battery in my Expedition I’ll take a look and compare to the NAPAs.
