Learn more about Rechargeable BatteriesAlmost all airsoft AEGs use rechargeable batteries. These batteries vary from your standard rechargeable NiCd battery, to your more efficient NiMh rechargeable battery. Airsoft rechargeable batteries come in a variety of voltages, milliamps, and sizes. It is important to make sure to buy the right size and voltage battery for your AEG, to ensure proper power and fitment. We recommend that all airsoft rechargeable batteries (excluding Li-Po batteries) be charged with a smart charger, which not only charges the battery in a fraction of the time a standard wall charger takes, but also extends the life of your airsoft battery! Airsoft Megastore is proud to bring you a large selection of airsoft batteries for every type of AEG, and offered at the lowest price on the market.
