You can do serious electrical damage if you jump the battery while it is in the vehicle. Do not do that.
I would suggest you buy an interstate MTP-91, adjust the mounting bracket (takes a little work), and mount the battery snugly.
Then get a Deltran or Interstate battery tender and connect it to an electrical snap-on fitting behind the driver's seat.
When not in use keep the tender attached via the snap-on fitting.
You will never have another problem,a nd the car will spin over like a rocket ship.
If you need details I can provide those.
