Ernie Ball has introduced a new line of USB-C rechargeable AA and 9V batteries designed specifically for guitar gear. These batteries are optimized for use in effects pedals, active pickups, wireless systems, tuners, and other audio equipment, offering a more reliable and sustainable alternative to disposable batteries.
Why These Batteries Matter
Traditional rechargeable batteries often struggle to deliver stable voltage, which can cause tone changes or noise issues in pedals and wireless units. Ernie Ball designed these new models to maintain consistent output throughout their charge cycle—making them more suitable for pedalboards and performance setups.
Key Features
- USB-C direct charging (no dock required)
- Fast charging: ~80% in about 75 minutes
- Stable voltage output optimized for audio electronics
- LED charge status indicator
- Available in AA and 9V formats
Practical Uses for Guitarists
These batteries are especially useful for players who rely on:
- Active pickups
- Wireless guitar and IEM systems
- Analog and digital effects pedals
- Portable rigs and travel setups
Because they charge quickly and provide steady power, they’re well-suited for both live gigging and home practice environments.
Sustainability Angle
With many guitarists cycling through disposable 9V batteries, this release supports a growing move toward waste reduction in music gear. USB-C compatibility also aligns with the power connectors most musicians are already using for phones and interfaces.
Availability
Ernie Ball’s rechargeable AA and 9V batteries are available now through authorized dealers and major online retailers. Pricing varies depending on quantity and bundle options.
