2003 batteries go dead if undriven for 2 weeks
My 2003 2500HD D/A is not able to start due to battery state of charge after 2 weeks of not running. It has 2 red top Optima's and this is now occurring with great regularity. Have not measured static current drain but find this unusual. I had no issues with the factory AC Delco's of for the first year on the Optima's. I'm considering a Battery Tender. I used to drive her daily but now she's my hunting rig. It has 101500mi on it.
What do you think?
Measured Current draws today
Spent some time today checking each circuit that is fused to see where the largest current draw was. The nominal draw when everything settles down is 160mA. I found 140mA of this draw goes away when the fuse for "STUD 2" under the hood is removed. What now? Does anyone know or have data on nominal static draw?
