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.

Mazda Miata Battery Replacement
June 19, 2019
by on June 19, 2019

The battery fit perfectly into its place in the trunk, the posts in the right place and places to hook up the vent lines to the battery. Replacement was real easy. Good cranking power. Remains to see how long the battery will last.

Excellent Battery Choice for a Miata
May 26, 2019

I've purchased this battery more than once for our 27-year-old Miata. It is a sealed glass mat battery so is ideal for the trunk location. I have found that the lifetime of this battery is six years (with low annual mileage). The shipping is free and fast. I would definitely buy it again.

1994 Miata battery
May 24, 2019

I was a little apprehensive about buying this battery because it was cheaper than anything else I found online and would likely have been difficult to return. Also Miata batteries are rather different from most other car batteries. Long story short - I received the battery about 3 weeks ago. It fit perfectly. It appeared to be identical to my old battery. No problems so far with car starting.

Battery Mart provided the right battery for my miata for a good price and amazingly fast delivery. Battery was the correct size and terminal post orientation enabling easy replacement.

Great performance

I have a Miata, so the battery is an expensive one. This one was two-thirds the price and performs great!

Real good price on the battery. I like the way they have the extra support on the top of the battery for the hold down. The car turns over the best it ever has,very fast.

NOT a direct replacement for my 2003 Miata
May 21, 2019
by on May 21, 2019

Battery is smaller than OEM (Panasonic S46A24L), and has vent tubes at different locations, requiring some futzing and an additional part to attach vent tubes to vent. Also has plastic clips on top of the battery for vent tubes which get in the way of the battery clamp.

Good news is it started the Miata.
