Review on 🔋 High Performance Tenergy Airsoft Battery 8.4V 1600mAh NiMH Stick Battery with Mini Tamiya Connector - Replacement Battery for AK47 CYMA RPK PKM AEG Guns by Brad Schillings

Took about 7 hours to charge with Crosman factory charger, rotation speed probably twice as fast as original battery and lasted all day for about 1500 shots before it ended. started to slow down. Fits the receiver great, although the battery cable is about an inch longer, no problem unless you use a dust cover from a real AK-47 or 74. All in all a great test, I'd buy a Smart charger with, makes charging more efficient and eliminates the risk of overcharging.
