Nickel Metal Hydride cells, or NiMH, do not require discharging before recharging. They also provide much higher capacity for a similar size than a comparable NiCD.
This battery is one of the few batteries which will fit in the KWA M4S or M4 Tactical. It will also fit in most airsoft guns that require a mini battery. The chain battery is the ideal battery for any airsoft G36C, as well as any airsoft rifle with a crane stock.
This 9.6 battery has Deans plugs installed for better performance.
We recommend getting the AC-DC Universal Smart Charger for NiMh or NiCd Airsoft Batteries for optimal performace from the battery.
