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?
