Silva Extension Cable for Silva Headlamps

Silva extension cable for Silva headlamps — allows remote battery pack placement for cold-weather use and extended battery life.

The Silva Extension Cable connects your Silva headlamp to a remote battery pack, allowing you to keep the battery pack in a warm inner pocket during cold-weather use. Cold temperatures significantly reduce battery performance — keeping the battery warm maintains output and extends run time in freezing conditions.

Key specs:

• SKU: SIL221
• Compatibility: Silva headlamps (check model compatibility)
• Use: Remote battery pack placement
• Benefit: Cold-weather battery performance

Why it works:

Lithium and alkaline batteries lose significant capacity in cold temperatures — a headlamp that runs 8 hours at room temperature may run only 2-3 hours at -20°C. Moving the battery pack to a warm inner pocket via an extension cable solves this problem, maintaining full battery capacity and run time in winter conditions.

Ideal for: Winter campers, ice climbers, ski tourers, and anyone using Silva headlamps in cold weather. See also the Trail Runner 4 extension cable (SIL220) for that specific model.
