This article is a step-by-step guide for how to charge an airsoft battery without a charger. Disclaimer: We highly recommend that you only do this in a pinch and invest in an airsoft battery smart charger instead as soon as you can.
So, how do you charge an airsoft battery without a charger? Different types of batteries feature different charging mechanisms, and there’s no concrete set of rules that applies to how you must charge your battery. Generally speaking, you’ll need some specialized components like capacitors, diodes, and a breadboard to hold everything together. The basic steps to charge your airsoft battery without a charger include:
- Check to be sure the voltage of the wall-mounted charger suits your battery
- Change the connector head of the charger
- Connect the charger to the battery
- Plug the charger in
- Monitor until the battery is fully charged.
At first look, this may sound like a daunting task, but it’s not. All it takes is a knowledge of how to make the right connections. However, if you don’t want to go through the process, we recommend buying a smart charger to charge your airsoft battery. Smart chargers may even be better for your batteries because they typically feature special functionalities.
However, if you can’t get a charger locally, a DIY fix is possible. Read on for a detailed explanation of trusted steps you can adopt to charge your airsoft battery.

Step by Step Guide For Charging An Airsoft Battery Without A Charger
For starters, you’ll need a battery charger of any kind for this process. Do not try this if you are not familiar with how electrical wiring works because doing it wrongly can damage your airsoft battery.
Here’s a detailed step-by-step guide to help you charge your airsoft battery correctly.
Step 1: Check To Be Sure The Voltage of The Wall Mounted Charger Suits Your Battery
Wall-mounted chargers are usually the best options, so it’ll be best to find an old one that’s no longer being used but still works. Cross-check to be sure it’s a good match for your battery. The voltage is usually indicated in the label, but finding the label may seem somewhat difficult since it’s old. You can also use a multimeter to detect the charger’s exact voltage reading. If you are using a multimeter, plug the charger into a power outlet and turn your multimeter on.
Grab and stock the red probe of the multimeter into the connector. Then touch the metal tip of the black probe on the barrel. The multimeter will read, showing you the reading of the voltage that’s coming from the charger. If it matches the voltage requirement of your battery, you can use it.
Step 2: Change the Connector Head of The Charger
Since the charger is not designed for airsoft batteries, its connector will most likely not be compatible with the battery’s connector. Therefore, you’ll need to replace them with suitable connector heads. You can replace the connector head by simply stripping the wires to expose the metal interior.
The rule of thumb is to start by cutting off the charger’s connector head before stripping its outer coating. The stripped charger will expose two or more thinner wires of different colors. If there are more than two thinner wires, you’ll need to locate and work with the red and black wires.
At this point, you can either leave the thin wires bare or attach alligator clips if you have. Use your pliers or crimping tool to attach the alligator clips.
Step 3: Connect the Charger To The Battery
Replacing the old connectors in your charger with a new one compatible with your airsoft battery is probably the most challenging part of this process. After the replacement, you can just connect both items.
If you left your wires bare, you would just need to insert the wires into the connector until contact is established between the connector’s metal interior and the metal part of the wire.
However, if you’ve used an alligator clip, you can insert one of the prongs into the connector head and clip. Ensure that there’s contact between the battery connector and the metal part of the charger. Do not allow contact between the two alligator clips when plugged in.
Irrespective of your chosen method, always ensure that you maintain the same polarity during your connections. Wrong connections can damage your battery or cause worse disasters.
Step 4: Plug The Charger In
With the charger adequately connected to the battery, you can begin charging. Do not abandon the battery while charging, as this can be very dangerous. We recommend close monitoring to know when the battery will be fully charged. Your airsoft battery would be fully charged after about two hours.
While this is an effective way to charge your battery, you should limit the process to just a few times. It’s best to get an airsoft battery smart charger to ensure the better functionality of your airsoft battery.
