Hope the coding will work out for you.

It was common 30 ~ 40 years ago to buy a good battery and expect it to last six years or more; Many were sold with 72 month warranty. I took advantage of those at K-mart auto centers.
Sure isn't like that now. I didn't know Duracell even sold automotive batteries. I've bought Odyssey for Jessie's CLK hoping to find something that will last beyond 36 months; Time will tell.
I have a Zero Gravity 11 lb battery in the SRT6, but this cold weather has about done it in after five years. I put a Dakota with twice the amp hr rating and a few more pounds in the Limited, but it's only a little over a year old.
