Battery OEM Mazda or OPTIMA

Its minor but there are 2 different technologies in use...the red battery is designed for cold starting while the yellow was designed to handle added accessories...at least thats what i take from the website...it also says that if you use a red top in a car with enhanced car audio the warranty on the Red Top is void...take that into consideration...

That's why I got one for my '66 Beetle (12 volt conversion) It won't rust out the now repaired battery tray! Also, you don't want to put a super-hyper battery charger on them. They tend to like being charged on the slow side.

I splurged on a red-top a while back when I needed a new one because I had heard how good they were as a battery, but I did not know about the safety features you mentioned!

I just put a red top in my Scirocco, and it starts so much better now... I have seen lots of batteries fail, and nine times out of ten it's a cheap piece of crap like the duralast... The only batteries I have seen hold up in the long run have been Interstate batteries, and Optima's.

Go optima red top, 109@ autozone with a return core (your old battery) They are expensive for a battery, but they are worth it. Ask anybody on vortex about them, they know.

The previous owner of my VR6 killed a red top, by letting the car sit weeks at a time. After doing this for about a year the red top would not hold a charge. After driving it, and parking it overnight the voltage would be high 10's/low 11's....not good for starting a car. A yellow top was used as a replacement. It took the sits fine, because of it's design. Now a few years later I have the car and it still holds high 12's over a few days of not being started.

Louis, the Optima has a reversed polarity pole set up. You will have to extend you cables and now the positive post is very close to the fender wall. Pray that it doesnt slide during a hard turn.

I compared the dimensions of both batteries (stock vs Optima) and the Optima is shorter, skinnier, but like 1/4 wider. Optima did not fit, or would not fit without modification to the positive terminal. Ordered the OEM from Keffer.

For the price you pay if you aren't using the car daily, it is a waste of money. I've been through 3 of them now, 2 of which I replaced within there crappy 1 year replacement period.

I've had to return 3 Red Top's prior to their 1 year warranty for replacements. Only 1 of the 3 replacements is still installed, the other 2 have gone bad and have been replaced with generic O'Reilly's batteries, which i've had much better luck with.
