Acceptable battery drain.
I have a 1995 GMC full size pick-up that is having a battery problem. I don't drive the truck all the time, and when it sits the battery will go dead after a week or two. The only modifications to the electrical system are an electric trailer brake controler and an aftermarket stereo system. I replaced the battery with a Exide spiral cell battery, very similar to an Optima, because acording to Exide these batteries are supposed to tollerate long term storage without losing thier charge. Before I take this battery back to the store I want to be sure it's not my truck. We all know that a modern car will never have absolute zero current flow due to things like stero and computer memory like our Camaros, but how much is acceptable? I show a steady current draw of 8 milliamps with the subwoofer dissconnected, and 48 milliamps with it connected. Would you considder this too much?
