Klvr Batteries are designed for professional audio and AV use, delivering reliable performance in demanding environments. Built with custom 1.5V li-ion cells with a linear discharge curve, they behave like disposable batteries while offering the consistency and longevity of a rechargeable system.
1.5V output with a linear discharge curve
Up to 30% longer runtime vs. traditional rechargeable batteries
Rated for 1,200 charge cycles
Quick charging times: Approx. 2h 45m (AA) and 2h (AAA)
Designed for wireless microphones, IEMs, pro AV gear, hospitality, and more.
Compatible with standard AA and AAA devices across brands
Klvr Batteries are part of a complete system designed to simplify battery handling. Paired with the Klvr Charger Pro, they allow you to charge, monitor, and manage your entire battery setup in one place.
Each set of batteries is delivered in a Klvr Pouch, making it easy to organise, transport, and separate charged and used cells throughout your workflow.
Switching to Klvr means fewer battery swaps, less waste, and a more predictable workflow. Instead of relying on single-use batteries or inconsistent rechargeables, you get a solution built specifically for professional use.
The Klvr Pouch is designed to keep your battery workflow as efficient outside the rack as it is inside. Built for transport and day-to-day handling, it provides a simple way to store, separate, and carry your batteries between charging, prep, and use.
Whether you’re preparing for a show or collecting batteries after, the pouch helps you stay organized, so you always know which batteries are ready and which need charging.
The Klvr Pouch is also built for touring as it fits in your backpack, slides into your carry-on when traveling by air. All while keeping 48 cells protected and organized - from warehouse to venue, from storage to off-site production.
