how long do charge this battery-look at info plz?

Question

The rechargable battery itself says SCX7 8.4V 1200mAh
The charger says Class 2 power supply on the top
Input-120V AC 60Hz
Output-9V DC 600mA
By the way, this battery is for an airsoft gun. ( An upgraded UTG Warhawk to be specific)

Answer 1

If I read the charger output and the battery capacity correctly, at least two hours....but if it is a new battery, I'd go at least 6 to establish the battery's "memory". Hope this helped.
