San Luis Obispo, CA (November 5, 2025) –– Ernie Ball, the world’s leading manufacturer of premium guitar strings and accessories, is proud to announce a groundbreaking new partnership with Paleblue, the leader in sustainable rechargeable battery technology. Together, they’re launching a new line of USB-C rechargeable lithium-ion batteries designed specifically for musicians and creators who rely on dependable power both on stage and in the studio. Ernie Ball joins Paleblue in its mission to end single-use batteries and bring pro-level rechargeable battery technology to the musical instrument industry.
Available in AA and 9V formats, Ernie Ball USB-C Rechargeable Batteries by Paleblue deliver consistent, full-voltage performance across instruments, wireless packs, pedals, tuners, and more. Each battery features USB-C direct charging—no external charger required—along with LED charge indicators, a rugged reusable storage case, and an environmentally friendly lithium-ion design rated for over 1,000 recharge cycles. With recharge times as quick as 75 minutes to 80%, these high-capacity batteries (AA: 2750mWh / 1933mAh, 9V: 4500mWh / 500mAh) provide continuous, reliable power while dramatically reducing waste and long-term cost.
“I think rechargeable batteries are the only way forward in this industry. There’s too much waste when it comes to conventional batteries. You also have the added benefit of carrying less bulk which also reduces weight, especially when touring on a budget. I love the charging indicator lights on these new Ernie Ball batteries and absolutely love the included charging dongle to be able to recharge multiple at the same time.” — Henry Trejo: Guitar Tech for Red Hot Chili Peppers & Jerry Cantrell
Ernie Ball USB-C Rechargeable Batteries by Paleblue are the cleanest USB-C power source on the market. Ernie Ball has already placed the new rechargeable batteries in the hands of guitar techs for artists including Red Hot Chili Peppers, My Chemical Romance, Billie Eilish, Jack Johnson, Zac Brown Band, Jason Mraz, Turnstile, Nine Inch Nails, and more, for field testing and real-world performance feedback. The Ernie Ball USB-C Rechargeable Battery line is available now through select retailers throughout North America.
