Westco 12V31M Miata Battery

The Westco battery is simply the perfect replacement battery for an NA Miata. The Westco I replaced lasted about 8 years, parked outside thru 8 cold New Jersey winters. The Westco fits perfectly, has the terminals on the exact right locations for the stock wiring, and mates perfectly with the stock battery tie down. It also has the little ports for the vent tubes to route any gasses out of your trunk. It arrived in perfect condition, with a strong initial charge. This is the only battery I'll ever buy for an NA or NB Miata.

This is the one you want for a Miata. They last five or six years. They fit perfectly. They are maintenance free.
