Once again proving that this forum us worth far more than the nothing that I pay for it, I found myself replacing the battery and having this issue. Thank you to whoever took the time to read the manual first, rather than, like myself, ran screaming to the EOC forums.....
It actually 'corrected' itself within a few minutes of resting comfortably with the key out in, while sitting in the garage.
By the way, anyone looking for a higher-amp, but stock fitment battery, let me stick in my two cents:
Safe Start batteries,
www.safe-start.com, is who we use to stock our battery racks (for diesel trucks), and when I called, they delivered a group 51R, 510CA/625CCA/85 reserve amp, direct-fit unit, for (my wholesale cost) of $53.00, plus the core charge. Considering the original is labeled '410CCA', with no reserve rating, I'd say a greater than 50% increase in CCA was worth more than I paid. And when I say 'direct fit', I mean zero modifications period.
Now, to be fair, that was distribution pricing, but even if you added a modest 30% GPM into that (which is typical of service shops), you'd still have $75.00 wrapped up. And, since my battery was still not 'completely' gone (load tested fine down to 400amps), I can use it for a 12 base power supply for my bench projects until it finally dies. Certainly worth paying the $5.00 core charge.
It also comes with a 75 month, pro-rated warranty, but with 24 months free replacement. We've used these batteries for some time in much larger forms (Groups 78/85/65 are the norm for me), and I've never had a failure, so I think it might be a good alternative to the expensive Optima and Odyssey units.
