Short answer? It depends on the type of battery, and how much you use it.
Long answer? Here we go.
It surely doesn’t end there. You probably also want to know what sort of batteries last longer, and how long you can use them before they go kaboom. Or the opposite of that, at any rate.
Generally speaking, more expensive batteries last longer. Apparently, the age-old law is still going strong: if you want high quality, you should be prepared to pay more. If more expensive batteries generally last longer, that means that inversely, cheaper batteries will not last quite as long.
So in the beginning, when giving the short answer we spoke of battery type. That wasn’t very accurate, and that’s why you probably should not always depend on the short answer. The most important thing that determines the battery life of Airsoft batteries is quality, not type.
Airsoft Batteries – Quality, Not Quantity
You’re probably thinking, well, this is somewhat cliché. But it is what it. AEGs are powered electrically, so this means that the batteries are electric.
The batteries are not continually in use, as the battery only cocks the gun when putting on. Since AEG’s come with select-fire, you can fire the gun semi-automatically and automatically.
So basically you have two different modes of firing and both of them have different effects on the life of your battery. For example, if you love firing automatically, you only need to keep your finger on the trigger. Or if you like to fire singe rounds, you can pull the trigger once. There’s a simple logic at play here. The longer you pull the trigger, the quicker the battery gets exhausted.
Once the charge of the battery is done, you won’t be able to fire a single shot. If you’re in the middle of a duel, that’s a straight one-way ticket to losing the town. And that’s something you don’t want. That’s why it’s important that you get quality batteries.
According to Pyramydair, the quality of your gun can even have an effect on battery quality and thus battery life. Cheap AEGs, for example, make use of regular run-of-the-mill AA batteries. However, AEGs that cost more come with rechargeable batteries and their own chargers. Even more expensive AEGs don’t come with batteries because their owners may have specific battery needs.
So how do you know the quality of your battery and how long you can use it before it goes totally not KaBOOM?
There are two important things that you should know about Airsoft batteries. The first is their mAH rating and the second is their voltage rating. The mAh rating is important because it shows exactly how much power your battery can hold before it gets totally exhausted.
It follows that if your Airsoft’s battery mAH rating is high, you’ll be able to use it for longer. But here’s the catch. You can’t just pick the battery with the highest mAh rating. This is because of the higher the rating, the bigger the battery size. And we are guessing that your AEG (like most AEGs) can only fit up to a certain size of the battery.
So if you want longer-lasting batteries, you need to choose the battery with the highest mAH rating that is still the right size for your AEG. AEG batteries are sold in different mAH ratings, and you can find batteries with 600 to 2500 mAH. For field matches, most people use batteries that within the range of 1000 mAH to 1800 mAH.
The rate of voltage, on the other hand, determines how the available power flows. Basically, AEGs make use of two voltage rates which are the 9.6-volt battery and the 8.4 boot battery. The 9.6-volt battery is the strongest of the two, however, both voltage types can run the motor of an AEG. Although, the 9.6 volts will run it faster.
So How Long, Exactly, Does It Take For An Airsoft Battery To Be Exhausted.
Remember all we said about mAH rating and battery voltage? Yes? Good. You’ll be needing it.
According to conventional knowledge, 1 BB = 1 mAh. This means that if your AEG is using a 1500 mAh battery, it will be able to take 1500 shots ± 100.
What this means is that the actual length of time that you use the battery for is irrelevant. Whether a week or a day, what matters is the number of shots that you take.
If you really need to know how long your Airsoft batteries will last, we’ve got a tidy little formula for you.
Number of hours = capacity of battery x 1.4 or 1.5
Here, the capacity of the battery is its mAh rating printed on the battery or its charger. 1.4 or 1.5 stands for NiCad or NiMH batteries.
Now that you know how long your Airsoft battery can last for, you should know that it is important to charge it as well. Generally, Airsoft batteries should be charged for three to five hours. Again, it all depends on your battery size and type.
So, long story short, if you want your Airsoft battery to last longer, you need to get a better and bigger battery. While in-game, you also need to have a rough estimate of shots fired because that is the major determinant of how long your Airsoft batteries will last for. So choose your gun wisely!
