Core 2 Battery

What Our Gearhead® Experts Are Saying:

"I switched to the Petzl Core 2 Battery to cut down on waste and it’s been a total win. The USB-C charging is super convenient—I use the same cable for my phone and beacon—and the battery lasts through long weekends of climbing and camping. I keep a second one in my pack for multi-day trips and just swap it in when needed."

With the Petzl Core 2 Battery, we’re done fumbling with disposable batteries. This next-gen rechargeable power source brings smart, sustainable energy to our adventures with a USB-C charging port that matches the cords we already carry for phones and other devices.

Delivering a 1250mAh capacity and a lifespan equivalent to 900 AAA batteries, the Core 2 makes it easy to stay illuminated without creating extra waste. The built-in indicator light keeps us informed during charging, and the full recharge takes only 3.5 hours—just enough time to prep gear for the next day.

Built for cold-weather reliability and field-swappable convenience, the Core 2 ensures our compatible Petzl Hybrid headlamps stay powered whether we’re setting camp after dark, touring under moonlight, or heading out before sunrise. Compact, efficient, and planet-friendly, it’s a simple upgrade that makes a big difference in our lighting setup.
