A lightweight battery case for 3x AAA alkaline batteries that gives you extensive burn time during longer runs.
This water-resistant battery case can be fitted on the headband or be kept warm in your pocket by using a SILVA extension cord. The battery meets IPX5 standard: Water resistant; withstands heavy rain and water from any direction.
Silva's battery line-up gives you the opportunity to find the right balance between burn time and weight. The Trail Runner connection cable enables the use of either our USB rechargeable or alkaline battery – or why not both! Combine them in any way that suits your needs.
The colder it gets the less battery 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.
