Battery OEM Mazda or OPTIMA

I just have a red top Optima in there. It is the only batteries I'll buy after the one in my truck went through so much hell and survived many years of abuse.

Mine fit like a glove - no mods - no custom bracket - OEM battery cover fits perfectly.

If you want a great battery get an optima, other than that it's pretty much all the same to me.

Ive had my red top for 5 years no problems...

I've been using a blue optima for about 6 years now and still going strong... Yes yes I know its for marine applications

I used to have a red top optima in my race truck for vibration reasons but for this car I wanted something that would run the compressors (if needed) subs, etc.... while the car wasn't running and still have the balls to kick the motor over for a start. That is why I went with the yellow top, kinda like a deep cycle for your car. You can drain the hell outta it and it will still start your car for you. That and it last two times longer than your conventional battery.

I liked my old optima. lasted 7 years. I've heard the new ones are Interstate brand now and are no good. I will not buy again based on what I've been hearing. too bad.

Optimas are junk. They used to be good years ago but that time has passed.

Optima is the most overrated battery brand on the planet (I'm not saying the WORST, but they are way too well-known for being a slightly-below-average product). They used to suck when they were gel cell (gel cells all suck) and their more recent AGM (AGM itself is good) batteries aren't great. Made by Johnson Controls, a not-great company, in Mexico.

My Optima Redtop 8003-151 34R that I purchased through amazon kicked the bucket and cannot be recharged. Do not buy Optima Batteries from Amazon since they will send you back to Optima and Optima will tell you that Amazon is not an Authorized dealer.
