They came charged but of course not fully. Because it comes as set of 2 I haven't had to time this but I used one after 4 hours and it seemed to have a full charge.

Does the light flash when charging and stop when complete?

Yes, usb cable red light is flashing when charging, off after full charged.thanks.

Before storing batteries do they need to be charged fully.

It is better to charge fully for this kind of battery, You can charge 70%-90% for lithium battery. but it is better full charge NICd or NiMH battery.thanks. Best Regards Blomiky Mark Ma

The battery to replace says ni-cd aa 300mah 4.8 - would this be compatible?

Make sure your battery plug is same as this one, if same, it will work in your device. This battery is just bigger capacity, performance is same as yours if plug are same.thanks.
