Battery OEM Mazda or OPTIMA

A lot of people say the Optima is not a good battery anymore, but I continue to have good luck with them.

I use an Optima Yellow Top battery and it made a big difference. The Yellow Top is honestly just good for the car in general.

I’ve got Optima batteries in some of the more “Special” cars.

Yellow top is/was a hybrid cranking/deep cycle battery, once popular for putting big stereo systems in cars because it could handle the discharge cycles of running the system without them engine running.

Ive been using a yellow top for around 5 years in my CRV with no issues

had one in a car that rolled 4 times and it’s still working

I replaced the battery with an optima battery brand new I assume the high quality battery. If the battery was a problem would fix it but it did not and now I’m back to square one

OEM batteries are crap, replace it with something better, preferably an EFB one. Also, a healthy battery should withstand that time and even more, so yours was definitely at its end.

My car was sitting in parking lot with engine OFF and ignition ON - Android Auto was working and headlights/interior lights -> after about 15min music stops playing and I thought okay it's energy saver mode let me start engine.

But NOPE, there were some error messages, and engine couldn't start - battery was DEAD, I read battery are shit on new Mazdas and didn't want to deal with it myself and get it towed because of warranty.

Mazda uses cheap batteries, I have had to swap them on my last two CX5s
