Yeah, plus to honor the warranty, I had to ship it back. So, I had the Autozone and Westco batteries side by side. Same casings, pin marks, etc.

'Zone's is not a AGM.
After having a non AGM explode in my trunk, I only use AGM.
I get mine from O'O'O'Reilly.
1992 BnT, 93LE #737, 94M, 95M, 96M, 97PEP, and a few 90s

But apparently it was at one time so it is worth checking the current inventory if the 'Zone is close to you. I don't have an O'Reilly's in my area. The Marathon Battery made the most sense for me as it is currently a nickel under $100 with free shipping and no core charge.
I work for Oreillys, The battery is made my east penn, and I have had one of their batteries in my miata for almost 3 years now. We will put our batteries on a slow charge after it has been in the store for 6 months then if it makes it til 12 months in the store we do it again and at 18 months it get relabeled as a reconditioned batter and sold much much cheaper then a new battery even though it is practically a new battery.
I have a Deka ETX30LA, works really well. Small form factor and lighter then the battery it replaces.
The extra cca aren't required over the smaller deka's but as mine is a daily etc and the price difference was 40 dollars, got the bigger battery
Apparently Duracell makes the Miata AGM battery as well!!
You can buy them from a store called Batteries Plus, part number is SLIU1RT
Price is $109.99

Duralast 8AMU1R - AutoZone VS Marathon 8AMU1R - Amazon
Local VS Online
$124.13 (OTD) VS $99.95
Needs core exchange VS None
OEM size VS SAME
US made VS SAME
AGM VS SAME
460 Cranking Amps VS 400 Cranking Amps
370 CCA VS 320 CCA

5 yr warranty VS 1 yr
IMHO 5 yr warranty and supporting a local business outweighed the price difference. But then again I don't race.
That's another EastPenn battery: http://www.eastpennmanufacturing.com...ive-batteries/Originally Posted by Phatmiata
