Thanks Jerry, that saves me much effort for no gain.
As for the battery, minimum 7 years….never been on a tender, and the truck does sit a lot in wetter months (winter, we don’t have winter, just shorter days and some rain) sometimes 2 months and it has always just been there.
It is a situation where I would just say thank you for your service when I replace it. I will follow up on a load test.
