I have been running an Optima since #375 was new in 1993. Believe it or not, the most recent battery an Optima Red Top 8022-091 75/25 was just changed out in 2016 after 14 years of use. Now, that battery was always on a small battery Tender when the ERA was parked in the barn. I now use the Optima Digital 400 battery tender and charger on the new Optima 8022-091. Based on past experience, the Optima has more than enough cranking amps for my 428 and lasts a real long time to boot. My voltage regulator and alternator appear to like the Optima as well seeing that they are all original to the first build.
