Even if you get the voltage to indicate a fully charged battery, your
battery's capacity and lifespan is almost guaranteed to be reduced by
going flat. You need to have the battery load tested to see if it still
delivers close to the rated capacity. You can buy a load tester pretty
cheaply, and test it yourself. If you have a size 27 or 31 battery, the
100 amp load tester from Harbor Freight is all you need.

I used a pair of jumper cables and hooked up the dead battery in
parallel with an old but servicable battery I had at home and hooked
up the charger to it. After an hour I had about 7 volts. Now the
charger would recognize the dead AGM and is charging it. It was up to
10V overnight, so I am hoping it will finish the job. If so, then I
am back to figuring out what drained it or if there is an alternator
problem. I presume if I measure the voltage at each battery while
the engine is running it will be the charging voltage? If I get 14.4
volts or so at both batteries, then presumably my alternator is OK?
Then I would be back to the propane alarm issue as the most likely
culprit. Does that plan sound reasonable? Thanks- Dave
