   Is the adapter regulated to 12V, or is that the nominal rating? If the   
   latter, it should work, but I would certainly not leave it connected   
   unattended. You don't want to come back to find the electrolyte merrily   
   boiling away. Use a multimeter to measure the voltage out of the thing   
   open circuit as well as connected to the battery and check it   
   periodically so it doesn't overcharge.
