Very simple - recharged battery and can't start up

[Loyn]

I'm not very technologically minded unfortunately, very new to biking!

I was subject to the ultimate schoolboy error in leaving my handlebar grips on over night and running the battery flat.  So I went out today and bought a charger, took the seat of my CB-1, pulled the batter slightly out of its housing and connected the crocodile clips to the relevant bits to charge it.  It's not yet fully charged but about an hour in I decided to see if I could start it up, so with the charger still connected I turned on the ignition and tried to fire her up.  It gave an initial small rev and then stopped abruptly to be replaced my clicking.  I left it another hour and this time disconnected the charger and everything and tried to start it again.  The same clicking, no king of revving or turning over. 

Have I dislodged something or blown something (by trying to start it connected to the charger)?  Or do you think it might just need to charge over night?

Thanks.

Possible it just needs to charge over night. When you are charging it, you have it disconnected from the bike right?

What amps is your charger rated at? If it is more than about 2 amps it will cook the battery. The best thing to do for any motorcycle is to get a float charger (Battery Tender). It will maintain the battery at peak charge and can be left connected for any length of time. Almost any automotive charger will put out more amps than the battery can accept. It sounds to me like the battery is at least dead and likely cooked.
