Charging li-ion battery

[footsoldier]

I’ve managed to misplace owners manual (430) and can’t work out where to clip the charger to the battery...seem to be lots of options!
Can anyone point me in right direction - online manual/video or pic.
Thanks!

Ok, I couldn’t see markings and there are various bits sticking out..
Will put glasses on and look again!
