I have or had two good car batteries one was a deep cycle they were connected to a 20 Ma led it could have been as long as four months since solar charger stopped working on top of that they were outside in temperatures as low as minus 25 degrees fahrenheit, what I want to know if one took a new battery and did this to it can it be brought back to make work as a battery should or does this cause a battery to completely fail. I had these batteries on a 30 amp charger for 10 minutes but they do not take much of charge only four amps for two batteries is not much for dead batteries usually when you crank a vehicle a long time and run battery down and hook them to a charger they will draw at least 10 amps each. I do not know if the acid can freeze in a dead battery these do not leak.
