In airsoft shotguns, batteries are vital components ,particularly in  electric guns (AEGs). They power the gearbox, allowing the motor to compress and release the spring, generating air pressure and propelling the BBs. Airsoft gun batteries enable semi-automatic and automatic firing modes, facilitating rapid and continuous firing with a single trigger pull. Airsoft voltage and capacity of the battery impact the rate of fire and overall performance of the shotgun . Best airsoft battery can enhance the gun’s power and efficiency . Airsoft AEG  batteries are necessary in ensuring the functionality and enjoyment of the airsoft shotguns.

Types of Airsoft Batteries

Nickel Metal Hydride (NiMH) Batteries:

NiMH batteries are one of the most traditional and widely used types of airsoft batteries. They are known for their reliability and affordability. NiMH batteries are available in various voltages and capacities to suit different airsoft gun setups. They are rechargeable and can be charged using standard NiMH battery chargers. However, they have a lower energy density compared to other battery types, which means they may not provide as much power and runtime as other options.

Lithium Polymer (LiPo) Batteries:

 LiPo batteries have gained significant popularity in the airsoft community due to their high energy density, compact size, and ability to deliver high discharge rates. They offer more power and longer runtime compared to NiMH batteries of the same size. LiPo batteries are available in various configurations, such as 7.4V, 11.1V, and higher, providing different levels of performance. They require specialized LiPo balance chargers for safe and proper charging. Proper handling and storage are important with LiPo batteries, as mishandling can lead to safety risks like swelling or fire hazards.

Factors Affecting Battery

1 Voltage

Voltage of the battery is the measure of battery’s power refers to how much electrical pressure the battery provides to the system.That’s why voltage affects the power and performance of the airsoft pistols and guns .The higher the voltage of your battery,greater will be power delivered to gun’s motor,it will result in increased rate of fire and trigger response.Airsoft batteries are available in a wide range  of voltages between 7.4V and 12.8V.However, using a higher voltage battery may put additional stress on the gun’s internal components  such as the motor or gears.

2 Capacity

The capacity of a battery is measured in the milliampere-hours (mAh).It indicates the energy of the battery and measures how long your battery will power the gun efficiently before needing to be recharged.A battery with a higher capacity can supply power for a longer duration compared to a battery with a lower capacity.Choosing the appropriate battery capacity for airsoft guns depends on various factors such as the desired runtime, playing style, and the specific requirements of the airsoft game or event.The more mAh you have, the better it is.For full auto action ,you must have 2000 mAh battery capacity per airsoft day.For semi auto 1500 mAh battery is enough for a long airsoft day.

3 Discharge Rate

Discharged rate often  represented as a “C” rating  indicates the rate at which the battery can supply power to a device or system.In airsoft batteries, the discharge rate is particularly important for high-performance setups or upgraded airsoft guns that demand higher power outputs. A higher discharge rate allows the battery to deliver more current to the motor, resulting in increased power and performance.A  battery with a discharge rate of 20C can deliver 20 times its capacity in current. So, a 2000mAh battery with a 20C discharge rate can provide a continuous current of 40A (20 x 2000mAh = 40,000mAh = 40A).Higher discharge rate batteries can handle the increased power demands of high-performance airsoft guns, such as those with upgraded motors, gears, or spring setups. These batteries ensure that sufficient current is supplied to the motor, enabling faster trigger response and higher rates of fire.

4 Charging and Discharging

Proper charging and discharging of an airsoft battery  can significantly impact its overall lifespan and performance .Charging the battery to its recommended capacity and avoiding overcharging or undercharging helps maintain its performance and lifespan in airsoft pistols.Overcharging can cause chemical reactions within the battery that result in the degradation of its components, reduced capacity, and overall shorter lifespan.Repeated undercharging may lead to a gradual decrease in the battery’s maximum capacity over time.

Allowing a battery to discharge completely or to a very low voltage can cause damage and reduce its overall capacity. Deep discharging can result in irreversible chemical changes within the battery, leading to decreased performance and shortened lifespan.By adopting proper charging and discharging practices, such as avoiding overcharging, deep discharging, and undercharging, it is possible to extend the lifespan and maintain the performance of the battery.

5 Maintenance and Storage

Proper maintenance and storage of an airsoft battery are crucial for preserving its performance and extending its lifespan. Regular cleaning of the battery contacts and connectors ensures optimal electrical conductivity, preventing any hindrance in power flow. Periodic inspection of the battery for damages, such as frayed wires or swelling, allows for timely replacements, preventing further issues. Using a compatible charger and avoiding overcharging are essential to prevent damage to the battery’s cells and maintain capacity. Additionally, avoiding deep discharges and storing the battery at a partial charge, around 40-60% of capacity, prevents capacity loss during storage. Storing the battery in a cool, dry, and well-ventilated place away from extreme temperatures safeguards it from potential damage. Regularly inspecting the stored battery for any signs of damage or leakage ensures safe usage. By adhering to these maintenance and storage practices, airsoft enthusiasts can enjoy optimal performance and a prolonged lifespan for their batteries, enhancing their overall airsoft experience.


In conclusion, airsoft batteries play a vital role in powering electric guns (AEGs) and ensuring their functionality and performance. The voltage, capacity, and discharge rate of the battery directly impact the rate of fire and overall efficiency of the airsoft gun. Proper charging and discharging practices are essential to maintain battery health and longevity. By adhering to these guidelines, airsoft enthusiasts can maximize the lifespan and performance of their batteries.
