2011 Explorer Owners- It may be time for a new battery!

[RandyH2]

FYI- the 2011 vehicles are reaching the end of the typical lifespan for an auto battery. Mine died recently and there is essentially NO WARNING from the vehicle before the battery goes bad. With the onset of Winter, a $130-180 maintenance should be in your future planning. Replacing the battery is VERY easy so don't feel like you need to have the dealership do it. I know our local parts store will replace one for free while you wait, if you don't want to tackle it yourself.

Also consider some new batteries for your key fob. Cr2032, I think. Don't do them at the same time as the car battery... Fair warning!

There doesn't seem to be any predetermined life span for these batteries. They have been replaced in as short a time as a couple weeks and as long as several years.

I replaced the original battery in my '07 Ranger in February this year. I didn't replace it because it was bad, I replaced it because it was 9 years old.

Replaced the one in our 2011 November 20, 2015........hard failure.

these things like to eat batteries, get the biggest most expensive one you can buy... that's fits. I personally have had bad luck with Costco Kirkland batteries but they do have a good warranty. I prefer "Odyssey" brand batteries but haven't forked out for one yet . On another note the lithium batteries aren't over 3K anymore, notice the weight.
