This Mazda Miata battery 12V31M AGM by Westco made by East Penn is special in both size and design.

Since it’s located in the trunk close to the rear quarter panel, it’s subject to physical damage in the event of an accident. An exploded battery is not good, so Mazda designed the battery to be “AGM”, which is a sealed battery free of liquid unlike the common batteries you’ll find at Wal-Mart. It can be flipped any way and won’t leak, plus will maintain the OEM design as it was from Mazda.

The Westco Miata battery utilizes absorbed glass mat technology for more cranking amps than a standard Miata battery. This New design, terminal location is OEM correct and installation of this Miata battery is easy.

*UPDATE 2014: The battery industry has done away with in-house testing, the 475 CCA was based on in house room temperature Midtronics tester, but starting this year these ship with independent lab test spec of CCA measured at 0 degrees F for 30 seconds (which is 320 CCA for this battery). Same battery, just a much more demanding test that may or may not reflect your local conditions. How many of us live in 0 degrees? Here in San Diego average day is 70 F and the battery can make 475 CCA here. Regardless, for those who have used and depended on Westco for all their Miatas going back two decades just understand the battery and the CCA it offers hasn’t changed, just the testing standards.
