If you're like most people, you probably don't know how to put a 26s on a charger. Here's a quick guide to help you out.
First, find a 26s charger. You can usually find these at electronics stores or online. Once you have the charger, plug it into an outlet and make sure the light is green.
Next, take your 26s battery and insert it into the charger. Make sure that the positive and negative terminals are lined up correctly. If they're not, the battery won't charge properly.
Once the battery is inserted, the charger should start automatically charging it. The light will turn red when it's done charging. At this point, you can remove the battery and use it in your device.
