Premium quality absorbed glass mat technology (AGM) is ideal for the Mazda Miata. The Marathon AGM Battery was designed for more than performance; it was designed for the enthusiast. Completely spillproof and leakproof; frequent replacement and high maintenance are over! The AGM technology increases power while improving driver and environmental safety. The key to this technology is the highly porous microfiber separators, which completely absorb and trap the electrolyte. Molded top and side connection terminals provide versatility, increased strength and durability. The Marathon AGM Battery provides the most advanced power and value in the industry.

Our replacement Miata batteries are sealed, maintenance free AGM rechargeable batteries. Due to their construction, they do not require any ventilation, can be mounted in any orientation, and do not require maintenance.

The battery features two vent tubes to attach your original vent hoses. These are not required for installation, but are offered to give you a place to attached your original hoses. Some modification may be necessary.

100% Perfect Fit For My 2003 Miata
February 1, 2018
by on February 1, 2018

I couldn't be happier that I chose this supplier, and this battery, for my Miata. It came to me quickly and very well packaged, and it fit perfectly in the confined space of the trunk. The "vent connections" were a perfect fit. Installation time was only about 1/2 hour, which was great. It seems like a great battery, and the price was very reasonable compared to the retail outlets in my area. I highly recommend Battery Mart based upon my experience.

The only bad thing about the AGM battery is that once it is very low, there is no bringing it back! We accidently left a light on and killed our other battery after 1 year. The battery before that lasted 7 years!
Great replacement battery. Battery Mart had an excellent price for the Miata replacement battery. The battery was shipped on time and arrived in great condition. We popped in the car and took off!

I had a hard time fonding a battery for my 91 Miata. I looked online and found Battery Mart. They had the right battery at a reasonable price so I ordered it. The battery arrived in a couple days! It was quick, easy and the right item. I would buy from them again!

Replacement Miata NB AGM Battery
November 29, 2017
by on November 29, 2017

After much procrastination I finally got around to installing the fine new battery I bought from Battery Mart. It went right in without a hitch other than I needed to use scissors to but the very ends off the factory vent tubes because they were square and the replacement battery has round vents to plug those two hoses into. These let gasses that build up in the battery while charging to escape outside the vehicle. I can only hope this Marathon battery lasts as long as the original Mazda battery did, 14 years!

The new battery comes fully charged so all that is needed is to remove your old gonner and install the new one. Always use a hold down strap or bracket. No battery should ever be allowed to flop around. It is always a good idea to disconnect the negative battery terminal first and reconnect it last.
