Plug and Jump

Problem grows out of a six month old RG battery that won't hold a
charge for two weeks. Bought a plug and Jump from Aircraft Spruce.
Neato idea; I don't have to remove the cowl. I was going to use it to
trickle charge the battery. Trouble is, when I plug in the Plug and
Jump, it powers the panel. I don't want the gyros spinning for hours
while the charger is charging the battery. What's a mother to do? C172N
model.
