Buying and Charging an Airsoft Battery
Airsoft guns are firearm replicas that simulate the appearance and recoil action of their
authentic counterparts. While historical re-enactors and gun enthusiasts use the replicas for recreational purposes, the military and law enforcement use the weapons for training
sessions.
The electric models have rechargeable batteries, which supply the power that fires non-lethal plastic projectiles. Understanding the these devices will enable you to select an airsoft battery that meets your requirements.
Types of Airsoft Batteries
Some airsoft gun owners use 8.4v or 9.6v Nickel-Cadmium, or Ni-CD, batteries. Although these economical batteries charge and discharge quickly, they can sustain irreversible damage if you accidentally overcharge them. Improper charging causes the cells to split and leak, which can ruin your gun. These cellular changes impair the battery’s ability to take and hold a charge as well.
Like Ni-CD devices, Nickel-Metal Hydride, or Ni-Mh, batteries are available in 8.4v for smaller guns and 9.6v for larger weapons. These batteries perform better in cold weather than Ni-CD, and they are less susceptible to damage from overcharging. Ni-Mh batteries are fairly inexpensive and available in various voltages and configurations. These batteries last longer than a Ni-CD battery and are the most widely available manufacturer and aftermarket battery.
Lithium-Polymer, or Li-Poly, batteries can withstand extreme temperatures better than more commonly used devices. This powerful airsoft battery also holds a charge longer than other types of batteries. The safest way to charge these devices is to use a Li-Po charger/balancer that is equipped with a timer.
Charging an Airsoft Battery
Rechargeable batteries require regular charges to provide optimal power to the weapon. Check your airsoft manual for details on the proper way to charge your battery because the process can vary based upon the type of weapon. You can determine how long you should charge your battery by performing a simple calculation.
The first number that you need is the milliamps (mA) of your weapon. Most airsoft guns require a total charge of 1,000 to 3,000 mA. The higher the mA rating, the longer it will take to charge the battery. The next number is the rate of the charger. Battery chargers are rated according to how much energy they can transfer over a specific time. This number is known as milliamps per hour, which is abbreviated mA/h. The battery voltage should not exceed the charger’s output.
To calculate the time required to charge the battery, divide the total units of mA for your particular battery by the mA/h rating of your individual battery charger.
If your battery is 3,000 mA and your charger output is 500 mA, divide 3000 by 500. It will take 6 hours to charge the device.
Generally, smart chargers eliminate the guesswork and stress associated with charging your batteries. To ensure that your charger delivers the full rated amount, plug it directly into an electrical outlet. Do not use an extension cord because this can prolong the charging time. Contact your local battery retailer for assistance selecting an airsoft battery.
