Cold Starting Difficulty - update!

[edison]

I had trouble getting the bike to start though it came close a few times during the cold weather this morning.....this is after freshly charging the battery the night before (full green light from the charger). It did turn over no problem when I jump started it with my truck (engine off!) - seems it has just needed a few extra amps (?). The bike had been sitting for a few weeks......

The bike runs fine...is this just a cold weather issue / sitting too long? Thanks!

Update: Replaced the battery with a new Yuasa and it started fine....the old battery was only 2/3s the size of the Yuasa ( I got the bike used) - so I wonder if that was up to the job to begin with.
