I just went out to use my car. It appears that the 12-volt battery under the hood is dead. I cannot get any juice at all. It has been very hot here lately and the car is sitting outside. Can I take the battery out and put it on a trickle charger?? The car is almost 10 years old but I have not had any problems. There wasn't any indication that the 12-volt was dying. I tried to use the Honda website chat but they said they would get back to me. Same problem when I called the dealership. Anyone know if it is OK to charge the 12-volt or do they just die and need to be replaced??
