Truck battery eval
Hi guys! I figured the folks here could explain to me what's going on with the batteries under the hood of my truck. I have a 2006 Dodge Ram diesel 4x4 short bed truck. It has 70,000 miles on it ...

The way I look at it, batteries start truck they are good!
Batteries fail to start truck they are bad time to replace both!
Normally, I'd say the same. However, the other day, my truck threw an engine code. Can't remember what it was, but based on truck forums, the problem was low battery voltage sensed at the ECM. Fix was to replace the batteries or poor battery connection.
My connections are fine, but the code is indicative of a weak battery, even though they test good with a 100amp load.
I think the batteries are just getting sulfated. I just had never seen voltage at 12.4 and specific gravity so out of whack with each other. conflicting each other.
