The Silva Free Headlamp Battery options allow you to customize your Free series headlamp to suit your lighting and activity duration needs. The more light (higher lumen) you want, the more powerful battery you need to bring with you. If you want to use your headlamp for shorter runs or activities, the smaller (XS, S) batteries are enough. If you’re going to be out for a long time, it’s better to choose a M or L battery and instead attach it to your helmet, to a handlebar or put it in your backpack using the extension cable. The Free batteries meet IPX5 standard (water resistant) and withstand heavy rain and water from any direction. The LED battery indicator will show battery status when charging or when turning on your headlamp, and ensures that you can keep track of how much power remains. Simply recharge your battery via a USB-C cable.
