You might take a quick check of the output voltage when set to 12v. A good charger will limit the output to about 14.5v. A cheap one may let it run to maybe 18v. The charger is supposed to regulate the current to the setting BUT cheap ones may not. The low or dicharged battery will draw all the charger will allow because the internal resistance is almost zero. Overvoltage will ruin a battery quickly, too many volts = overcurrent = heat = warped plates = internal short = more current, Etc. Etc. (Maybe a big bang)
I suppose I should have said cheap OR defective.
