The Trail Runner Hybrid Battery Case can carry either the Silva rechargeable Hybrid Battery or 3xAAA batteries. The case has grip friendly surfaces and holds an integrated red rear safety light – adding extra visibility. The battery can be carried comfortably on the headband or, thanks to the extension cord, it can be kept warm in your pocket to save battery life.

The battery case is water resistant and meets the IPX5 standard; withstands heavy rain and water from any direction. Thanks to the built-in red safety light you do not need to add an extra light to your headband for increased visibility – this is perfect for trail running competitions as well as everyday running. The Hybrid Battery Case is really lightweight and only weighs 53g with the Hybrid Battery 1.15Ah and 62g with 3xAAA batteries. The Trail Runner Hybrid Battery Case is custom made for headlamps with the Trail Runner series and fits Trail Runner 2X, 3-, 4- and Free series.

Stay warm for better capacity
The battery capacity could depend on your body heat as well as the outside temperature. The long extension cord from Silva gives you the option to carry the battery close to your body. This could be crucial in many ways. Keeping the battery as warm as possible in cold weather extends its burn time.
