How to Replace a Battery on 2015 Mazda 6. It Started Hard So I Replaced the Battery

My wife’s 2015 Mazda 6 had hard start problem when it was sitting in cold for longer periods.
Our car DOES NOT come with the i-ELOOP system and we could use standard battery. Definitely the battery couldn’t provide enough power in to start the car smoothly in cold weather.
I decided to replace the battery on the Mazda 6 and the car starts without any trouble every since. I was lucky to record this video before the Polar Vortex of 2019. In result the car started in the sub-zero temperatures we had for few days.
Any way, if you wonder how to replace battery in Mazda 6 – this video will show you how to do it – Enjoy

Fritz Arriate says:

I owned a mazda 6. The technician form mazda told me to reprogram the unit if the battery is replaced. Is the advice of the technician right?

That's it? No need to reprogram immo?

Patrick Stewart says:

That not the correct battery for i-Eloop. It should be a Q85. Sercch for the Mazda TSB E039/12….The Battery Part Number: PE1T185209U . Expect codes, short life and other problems if you don't install the Q85. Choose wisely !


Que amperes tiene la batería

Great video!

Zappacosta says:

I noticed you didn't use a battery tender to prevent the rough shifting and stalling resulting from the re-learning the ECU must do after a complete battery loss.
