All air guns (AEG) are powered by batteries. The performance of AEG depends largely on the quality of its battery and the type of battery used. Before we research which battery is best for your particular AEG, it is important to understand the terminology used when talking about batteries.
Battery: This is a container with chemicals, used as a charge.
Battery pack: This is a set of batteries that are connected together to increase the overall energy output/voltage.
Voltage: Voltage is the potential energy output per unit. The air gun uses two types of voltage. The first is the voltage of a single battery. The second is the total voltage of the entire battery pack. (Normally, the higher the voltage value, the higher the air gun's rate of fire (speed). However, higher voltage air guns can cause excessive gear wear, which shortens the life of the air gun, although many high-end air gun guns can withstand this Wear.)
Milliampere hour (Mah): The milliampere hour determines how long your battery can power the airsoft electric gun before it needs to be charged. The higher this number, the longer it can be used without payment.
Discharge: Discharge is the process of consuming all the energy in the battery or battery pack. This is done to maintain certain types of batteries.
Charger: The charger is used to transfer electricity to the battery.
Balancer: A balancer is a device that distributes energy evenly to all battery cells and absorbs energy from a ber battery to a weaker battery to keep all batteries balanced. If you charge a lithium polymer battery, you need these.

Air gun batteries are mainly divided into three types: nickel-metal hydride (Ni-Mh), nickel metal cadmium (Ni-Cad) and lithium polymer (Li-Po).
Ni-Mh batteries: These are the most common batteries in air guns. They are easy to maintain and charge, and generally have a higher MilliAmp Hour rating than other batteries. They can be charged without a balancer, but it is highly recommended to use a smart charger (a charger that determines whether the battery has reached its energy capacity). These batteries have multiple configurations and can be used to power any air gun. It is important to note that not all nickel-metal hydride batteries are the same, so it is always beneficial to buy high-end nickel-metal hydride batteries to extend battery life and increase output power.
Nickel metal cadmium (Ni-Cad) batteries: These batteries are generally considered outdated because they contain highly toxic chemicals and cannot maintain charge for as long as Ni-Mh batteries. Nickel-cadmium batteries also require more maintenance because they may become useless if they are not fully discharged between uses.
Lithium polymer (Li-Po) batteries: These batteries are sweeping the world of air guns, in part because they provide very low resistance power for air guns, which improves performance, and also because of their service life ratio between two charges Standard Ni-Mh battery. However, lithium batteries do need to be careful and safe when charging. Lithium polymer batteries must be charged with a balancer, because if a single battery is overcharged, it may quickly overheat and cause the battery to catch fire. Lithium batteries do increase the rate of fire of most air guns, but the increased speed will cause the air gun to wear faster. Before use, make sure that your air gun can handle lithium batteries.
Charging: The standard wall charger that comes with the air gun is never the best way to charge the air gun battery. Without supervision, it may cause damage to the battery and invalidate it. To avoid damage to the battery, it is important to use a high-quality charger. Generally, when charging a NiMH battery, a smart charger is the best choice, because it can charge the battery in less than half the time, and can prevent the battery from overcharging.
When charging lithium batteries, be sure to always use a balanced charger. This can reduce the risk of overcharging the battery and maintain the health of a single lithium battery.
When considering which battery to buy for the air gun AEG, it is important to determine the voltage required to power the air gun and whether the battery can be inserted into the battery compartment of the AEG. After choosing a battery suitable for gameplay and airsoft, please make sure the charger is installed to make the airsoft battery in the best condition. Ultimately, the airsoft battery is only as good as the charger.
