Battery OEM Mazda or OPTIMA

Bought a redtop Optima battery for my 97' GTI VR6 a little or a year ago. Fit great in the engine compartment and still putting out tons of juice like the first day I cranked it over.

Currently I run a blue top marine battery, I hardly ever drive my jetta anymore. Will start up fine after sitting for weeks or even longer. Love it!

I have always used an optima red top for all the cars I have owned. Never had an issue.

I have run an Interstate battery without issues for the last year, but recently switched to an Optima Red Top. Although I had to get creative in mounting the fuse box on top of the battery, it is nearly 200-300A more than the Interstate in regards to CCA and CA. I am highly impressed. My Escort 8500 has a built in voltmeter. When I would sit at idle with the Interstate battery with all accessories running (lights, A/C, radio) and with as hot has it's been as of late, I would get a low voltage warning (10.5 VDC) when it activated. With the Optima I have yet to see one.

I've got an optima yellow top & it fit w no problem. No modification whatsoever. You just gotta make sure tha +/- (positive/negative) are reversed.

I think we have an Optima in our Mk1 diesel.

Your Optima might never be the same now. Once they go dead they usually don't have the same charging and output capabilities.

Optima batteries are not as good as they first were. Optima batteries have gone down in quality after being bought out, after Johnson Controls bought them and moved production to Mexico.

I had an Optima that behaved like this and took it back to AutoZone, they swapped it out without much hassle.

I've owned an optima before. Will never buy another one. I used one in my 4x4 to listen to music while camping, play it until the sub cuts out, get a jump, charge it and repeat. Ended up damaging the battery and it would never hold a charge and struggled to start the truck after a weekend of camping. Tossed it out after 2 years.
