Frozen Battery ????
Checked my Campers battery volts the other day with my digital volt meter, read .2 volts.
Assumed battery shorted out/failed or something.
Call AC Delco customer service, and was told:
Battery probably discharged and froze. Try letting it thawout and recharge, might come back to life. But was warned the, the fully charged AMP hrs. etc will be shortened/etc.
Customer service guy said when the battery discharges acid and water seperate and then water freezes. Therfore low to no volts across the terminals.
Even as I write this I have the battery setting out in the sun, thawing out.
Waiting to recharge it.
Weather it will work well enough after charge who knowes.
Thing that gets me is I have a disconnect switch on the battery terminal. And I thought I had the battery disconnected. I had went out to do some work in the camper several weeks ago, voltage was fine (12.2 v or so), connected battery plugged in camper, did what I wanted to do in the camper, unplugged camper and disconnected battery i thought.
Just thought I would post this maybe some would find this of interest.
