So I went out and bought one of these today after reading this thread, got home, took the flat battery of the cossie, followed all the instructions and it just will not charge.

Plug it in and the standby light comes on.
If I press the mode button once it lights up the 6v light, and again it then flashes the battery charge symbol. According to the instructions this means it's in pulse charge mode to recharge a flat battery (as opposed to a low battery) which is what I want.
However about 2 mins later it goes back to the standby light permanently.
Anyone who has one of these got any ideas? Or is this just my life being typically unlucky again and I've picked up a fucked one?
