Why do both batteries die?
I have a 99 e-150 wheelchair van with an auxiliary battery. It sat in cold CT. weather for 3 weeks. When my wife tried to start it no go, dead. Switched to auxiliary battery and there was not enough power to crank it over. I got it jump started and it was ok until trying to start it 3 days later. Main battery no power, switched to auxiliary and there was just enough power to start it. This originally started about 4 weeks ago. Today my wife went to start it and both batteries where dead. it seemed during that 4 week period if the van was ran every 2 day it kept a charged. The battery is a year old Advanced Auto Silver. The auxiliary is over 6 years old. My question is will I have to fully charge the battery before I bring it to A.A. for a test. I hope this ain't a dumb question but can the battery be charged while it's still hooked up. Or if it's jump started again and run on the highway of an hour will that be enough for an accurate test. BTW I know it's not the alternator because the lights never dim.

I'll keep you guys posted with the out come.
Oh, this is very strange. I thought maintence free batteries meant no playing around with water levels anymore.
