About

What to Expect from Klvr About Klvr Klvr builds professional rechargeable battery solutions designed specifically for AV and live production. Our flagship product, the Klvr Charger Pro, is a high-capacity 1U rack-mounted charger for wireless microphones, in-ear monitors, and other professional devices. It charges up to 48 AA or AAA Li-ion batteries simultaneously, delivering safe, sustainable power in a brand-independent system. Klvr Batteries are available in AA and AAA formats and use custom 1.5V lithium-ion cells designed to work with equipment built for alkaline batteries. By recreating the familiar alkaline discharge curve, devices report battery life predictably - removing the guesswork that often comes with rechargeables. Each battery is rated for up to 1,200 charge cycles, helping production teams reduce waste while lowering long-term operating costs. For AV teams, broadcasters, and live venues, Klvr provides a practical alternative to disposable batteries that completely outperforms traditional rechargeables - simplifying battery management without compromising reliability. Klvr was founded in Norway by sound engineers and live production professionals who experienced the limitations of disposable batteries firsthand. Today the company focuses on building robust tools that fit seamlessly into real-world production workflows.
