Depending on the car battery, better check the self-discharge rate. For car batteries, the self-discharge rate is fairly high. It gets worse with age too.
I don't have any accurate data on this, but once left a car with a new, fully charged battery at LAX for 38 days and had to call AAA to get a jump start. I had lifted the contactor before leaving the car in the lot too. So no phantom current was being consumed. The battery was fine, and lived a full life after the recharge - not defective. 73, matt, W6NIA K3 # 24, K2 # 2810 On Fri, 08 Feb 2008 22:14:23 -0600, you wrote: >Bob, > > I'm assuming you mean when it's "off."
