Re: Battery Dying
Find a local auto shop that'll test your battery, starter and alternator for free. If those all check out, maybe it's corrosion between the battery and the leads? Post back, let us know when you figure it out.
EDIT: actually, if it starts with a jumper every time, then it's something with the battery or connection. Like robpp said, it could be bad when it's under load... depending on what type of battery test has already been done on it, you may already have the answer to that question. If it tests fine under load, then it's probably corrosion between the leads and the battery nipples.
