Silva 4xAA Compact Battery Pack

Cold weather is the enemy of battery performance, and anyone who has watched their headlamp fade on a winter night paddle or ski trail knows how quickly it can happen. The Silva 4x AA Compact Battery Pack gives you a straightforward way to carry more capacity while keeping that power close to your body where it stays warm.

Running on four AA batteries, this pack sits within Silva's broader battery ecosystem, which spans everything from lightweight head-mounted packs for fast trail runs to higher-capacity options for long backcountry days. The compact, flexible form factor makes it easy to tuck into a jacket pocket or vest, and the extension cord lets you run the cable to your headlamp without restriction. Keeping the pack against your body in cold conditions meaningfully extends burn time compared to mounting it exposed on your headband.

The Silva Connection System means this pack is compatible with Silva headlamps from 2008 onward, so if the cable fits, it works. IPX6 water resistance handles rain, snow, and trail mud without issue.
