Battery OEM Mazda or OPTIMA

Unfortunately, I only ran that battery for 10 months.....car was stolen, so I can't say it was great for many years, but in 10 months time, not one hick-up......even when my Autolamps Online HID kit went haywire and turned itself on and stayed on ALL NIGHT.

I just replaced the red top Optima in my Cherokee after 8 years. Put in a yellow top Optima.

I have a red top optima. I was told that the yellow top is better if your running competition stuff in your car, ie stereos, strobes, neons, and such. 1st red top lasted about 5 yrs. On 2nd red top and have no problems with it.

I bought the Yellow top today . fits the TT perfectly . and also made room for the breaker for the power cable for the Audio setup . the original battery was a little taller and wouldm't clear the battery coverery. so I was worried about mounting the breaker too far from the battery, now its all good.

i had a yellowtop in my gti for several years. i got it from a friend who had had it as a second battery with his stereo install for 2 years. it lasted about 6 years total. bought a red top and liked it a ton. when my tt stock batt goes out, ill get one.

red top fits perfectly fine..no mods

Optima Yellow top is pretty good. Avoid the Red Top's like the plague.

Optima started to suck after they were bought out by Johnson Controls. I'll never use another one. I'd buy an Odyssey.

I had an optima yellow top in my Jeep for 3 years. Then all of a sudden a cell died without warning, leaving me stranded in the desert when I went to start it. I will never buy another one. The duralast I replaced it with has been in there for about 4 years now with no problems. It also cost less than half what the optima was.

Yellow tops are great, but since they switched the Redtop to the new design, it's a joke.
