The Death of my Battery

Anyone know how to bring a battery back to life? This one didn't respond well to being hooked up to the booster cables. After five minutes on the booster cables with the car running there still wasn't enough life to get more then a 'click' out of the bike when I tried the starter. I think maybe the next step might be to hook it up to a trickle charger and see if maybe that'll bring some life back into it....or I could just go buy a new battery. Nope, I'm too cheap for that, I'm going to try charging it first.
