Premium quality absorbed glass mat technology (AGM) is ideal for the Mazda Miata. The Marathon Miata 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.

This replaced the identical battery that I bought from Battery Mart 5 1/2 years ago. Good product and prompt delivery.

This is my second battery of this type. Last one was a Westo brand, but it is the same battery, both being made by East Penn/ Deka in Pennsylvania. I got 13 years out of the Westo so shopped around and found that Battery Mart had the best price for the Marathon.

Two weeks ago, I managed to leave the interior lights on and did not go near the car until last week. Battery was flat. I mean flat, zero volts measured across the terminals. With the battery disconnected, I measured across the terminals again and got 0.54VDC. I've never killed a battery that badly. I had nothing to lose so I put it on a 0.75A Battery Tender Jr for 2-1/2 days. The charger showed full charge. Yesterday, I took that charger off and put a Battery Minder 1.75 charger on and went thru its cycles and showed a fully charged battery. I put the battery in the car and a volt meter across the terminals. When I cranked the engine, voltage dropped to about 10.8VDC which is normal for any battery while cranking an engine. Engine started instantly. Ran several crank/start cycles and never failed to crank and start and battery voltage always recovered.

This is one tough battery. I would highly recommend it and will buy another, in about 13 more years. ;-)

The battery is a perfect fit for my 1990 Miata. It took all of 5 minutes to swap out the dead battery for the new Marathon one. Ordering online was a simple task and shipping was superfast...two days and it was on my doorstep. I am more than pleased with the whole experience from Battery Mart.
