Mazda CX5 battery inquiry

[Patrick0525]

We do both the key fob and vehicle batteries in CX-5s all the time. The vehicle battery is just a group 35,nothing special. And the keyfob battery is either a 2025 or a 2032 depending on the year. Sounds like your co-irker likes to do things the hard way.

@bdcardinal My co-worker went to a non-Mazda dealer for scheduled service, he claims resetting the personal settings drained the battery over a two week period. Is it that even possible? Does Mazda’s default setting somehow create a current drain even though doors are locked by the key fob?

I think his claim is a red herring and an urban legend. Lol

I think he was fed a line by them.

I think he was fed a line by them.

The line is what my co-worker concluded or rationalized from the battery failure. It was not from the non-Mazda dealer.

I am in my 60’s and want give back to my GenZ co-workers who may not received the knowledge and training from others. Recognition is not important but sharing knowledge that builds humility is most important life lesson.

And I tip my hat to you trying to help the younger generation, I just wish the person had a clue that not heeding your knowledge is going to be a hard lesson to learn. Yes I couldn't agree more, humility is extremely important in life.

All that attitude would make me question the job that person does at work.

Waiting for AAA really sucks when it’s December at the Detroit airport parking garage . Batteries don’t go out in your heated garage. Young and cavalier is fun but older and wiser is safer.

The car is a daily work commuter and battery #2 still has the remaining warranty. U are correct, batteries just don’t quit especially in a 5 yr old car that electrically shuts down when the key fob originally locked the doors.That evening the battery was so dead that the doors could not be unlocked until AAA jumped the battery. The situation speaks volumes of the battery’s degraded condition and the owner’s lack of urgency to investigate further since the DC trip somehow magically self-resolved any battery issues.

Jumping a no start car is one thing but an unresponsive door lock opening takes it to the next level. Since the CX-5 has a 2.5L engine, it takes a minimum of 250 CCA to start ( read it on this forum)

My wife’s car was 6 months old and I had tested the battery a month prior, 95% state of health. We drove 2 hrs to Detroit metro, parked the car for a week and came back to a stone dead battery. It was so dead the horn wouldn’t even chirp as we were walking towards it, and barely unlocked the doors. AAA jumped us and I drove straight to the dealer. After a day of testing they determined that it was just a bad battery. That was about 9 months ago. I do now carry jump packs in my cars.

Our 2014 CX-5 Has just 26K miles on it and it has the 2.0L. The original battery lasted nearly 6 years ad was replaced by me with a Duracell from Sam's Club that was from East Penn. Its now on its second Duracell and they are still made by East Penn. That little 2 L sounds like a tractor but has lots of power and gets just over 33mpg on our trips.
