9.6v 1600mah Intellect Nunchuk Battery (NiMH) Constructed of Nickel Metal Hydride, this battery is a great purchase for the intermediate to advanced airsoft player. The chemistry of its construction makes it low maintenance and cheap on the pocket. The capacity of this battery is 1600 mah, which translates into about 1600 shots before the battery will need to be recharged. This battery can typically go through 300 charging cycles before losing efficiency and eventually becoming useless for airsoft skirmishing. Also it only requires discharging for the first 8 cycles of use, after that it can be topped off as needed. Because of the higher voltage this battery will turn over a motor much faster and put greater strain on the internal components of your AEG. Remember to recycle this battery instead of throwing it in the trash! Note: Use of this voltage battery with non-upgraded (stock) Japanese AEGs like Tokyo Marui, will cause damage to your AEG if not monitored properly. Therefore we DO NOT recommend this battery for use in AEGs shooting less than 350 fps.
