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.”

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. 

ABOUT ERNIE BALL In 1962, veteran player and guitar teacher Ernie Ball created Slinkys®, the innovative light gauge electric guitar strings widely revered by thousands of iconic players including Eric Clapton, Keith Richards, Jimmy Page, Paul McCartney, Metallica, Brad Paisley, Slash, John Petrucci, Angus Young, and John Mayer. The strings are all crafted in Coachella, CA. Ernie Ball also offers state-of-the-art instrument accessories that are carried in more than 6,000 stores in the U.S. and 120 countries worldwide. Officially purchasing the Music Man® company in 1984, Sterling, joined later by his sons Scott and Brian, has built a team of dedicated professionals based in San Luis Obispo, CA who collectively share a common goal: crafting the highest level of hand-crafted instruments available. Originally founded by Tom Walker, Forrest White, and Leo Fender in 1974, Music Man built its name leading an industry revolution, introducing active electronics on its production instruments. As part of the team during the ’70s, Sterling Ball played an important role in the design and development of the iconic StingRay basses. The family-run company maintains its founder’s dedication to preserving the musician’s playing experience and delivering superior sound quality through the development of new products, such as Paradigm Slinkys, Cobalt Slinkys, M-Steel, Earthwood, Bell Bronze and the revolutionary Element Shield Packaging, keeping each set as fresh as the day they were made. The company also fosters artist development through musician-focused programs such as the world’s largest and longest-running unsigned artist programs, where bands compete each year to play live on national tours, festivals, and events.
