I have been a dealer since Optima started building Red Tops. I completely understand the application. I am explaining why not to use red tops in this truck, and why yellow tops are better.

What do the people that check the batteries tell you are wrong with them when you have brought them back in the past? shorted plates?

I would try what Gary suggested about first making sure the alternator is working and putting out enough juice. There might be another GM alternator that would put out more juice. I would find a good alternator shop and show them your setup and ask them to test the alternator. Also I bought a voltage gauge that plugs into the cig. lighter and it displays the voltage on the battery while you are driving and has a green,yellow, and red LED which shows if the voltage is staying in range to charge the battery. It is easy to test the alternator while driving around and turning on different accessories and watching the voltage on the gauge. Ask around and find a good alternator shop in the area.
This a GM 1 wire alternator? Maybe the rpms are not staying high enough to keep the alternator "on" while idling? If I remember right, it takes a certain rpm before the voltage regulator connects to the battery and turns on the alternator.
Goodluck
I've got 2 old Fords with a red top in each, both cars are used infrequently. One battery is about 7 years old and the other is about 2, no problems yet. Regarding new versus old, a friend owns a small shop and recently his Interstate distributor stopped carrying Optimas other than warrantee replacement saying the new ones were junk and was tired of replacing them. So maybe there is something to the change in origin of manufacture . . .
Lots of us have discovered that the Red Tops are overrated, expensive ****.
