pulling TT's batteries with charger on line?
My Springdale 266 has batteries on the tongue. I need to pull them out, clean under them and take them to NAPA or some such place to have them load tested. (They are original to the TT; 4+ year old Interstates)
The TT is presently plugged into 110V and with the battery charger running normally. Should I remove the batteries as is, or disconnect the TT from 110V first? I am not sure if the TT battery charger cares if it looses the batteries as a load or not.
