Troll ? I like that one.

Ben I too live in a cold climate and there are too many governing factors that could result in a dead battery so most just replace them to a larger newer battery and move on. I wanted to figure out what was the cause, weak battery or was there a drain on the system from something. I charged the battery and then put a amp meter on between the ground wire and the battery to see if there was a drain and there was. I didn't know what was acceptable so I just hunted for the largest one. I then started pulling fuses one by one until the drain of almost two amps changed and when I pulled the 12v outlet fuse the drain dropped to under a 1/2 amp. I remembered plugging in an adaptor that converted cig plug to usb outlet !! so when i unplugged it the 1.5amp drain was gone. Who knew an adaptor that went from 12v to 5v drew any never mind so much power, even when not being used. Most people don't want to put in the effort to track it down but you can do the same test to try and isolate the drain or get a battery maintainer or drive it more. :)
