Recently came out of work to a dead battery. Picked up a new one (drag) charged it up, checked the amps, hooked up the cables and started it up. Came back 2 days later to what seems to be a dead battery. Checked the cables, recharged on the trickle charger and nothing but click...click every time I hit the start button. I repeated this several times and tried to start it immediately after charging and nothing. So is just a bad battery that won't hold a charge or is there something else going on here draining the juice out and preventing it from turning over? Thanks.
