I have also left my TT pluggedinto 30 amps at home, have forgotten about adding water to the battery, and "cooked" it. I plan on getting one of these Battery Tender jr.

The Battery Tender Junior has a mind all its own. This smart tender automatically switches from a peak voltage of 14.4 VDC to a floating voltage of 13.2 VDC. When the voltage drops below 12.6 VDC, the Battery Tender Junior resumes charging at 14.4 VDC. Your battery stays at a constant, operational voltage. A two color LED indicates the state of the charger.
