Battery for 2001 Mzda Miata
September 25, 2022
by on September 25, 2022

The original Panasonic battery lasted 21 years. Time will tell with the battery I bought. I searched the web and this was the best price I found and the shipping was free. The battery arrived fully charged and package very well.

Excellent Quality and Lightning Fast Shipping

I ordered a battery for my 96 Miata from Batterymart. Not only did they have the best price of over 10 other vendors, they were the only place that offered free shipping.
The OEM battery on the 90-97 Miata is a very specific application. It is an AGM type due to its placement in the trunk of the car. Many other stores offer a “good enough” replacement, but Batterymart carries the actual OEM type for the Miata. It really is a safety issue.
I ordered the battery on Friday afternoon with no expectation of seeing it arrive for a week or so.
I received a message Monday morning that the battery was shipped and in-transit. Tuesday morning at 10am, I received a notice that it had been delivered. Fast shipping is one of several reasons that I highly recommend Batterymart and I will definitely buy from them again. Thank you!

Perfect for older MGBs

The only battery I've found to fit my 1970 MGB GT. Has the power and durability needed for a car that is not used a lot. Stays fresh with a battery tender over the winter. The battery got delivered to CT in 2 days, fast service.
