Ernie Ball USB-C Rechargeable 9V Battery by Paleblue – 2-Pack

Pro-grade rechargeable 9V power designed for musicians — no disposables, no voltage drop, no drama.

Who This Is For

If you run pedals, active pickups, a wireless pack, or a clip-on tuner — you go through 9V batteries. They die mid-set. They die mid-session. And they pile up fast. The Ernie Ball USB-C Rechargeable 9V Battery by Paleblue is built for the player who wants to stop thinking about batteries entirely. This is a serious, purpose-built rechargeable made specifically with musical gear in mind, not a generic consumer cell in new packaging.

Where old-style rechargeables fell short with early voltage drop and inconsistent output, these hold a steady 9V throughout the full discharge cycle — a real difference in high-gain and active-pickup applications. Whether you are powering a pedalboard at rehearsal or a wireless pack at a gig, this is the kind of low-maintenance, high-reliability solution that earns a permanent place in your gear bag.

Key Highlights

• Charges directly via USB-C — no external charger or dock required
• Reaches up to 80% capacity in approximately 75 minutes
• Rated for over 1,000 recharge cycles — equivalent to hundreds of disposable batteries
• Built-in LED charge indicators show you exactly where you stand before a set
• Constant, full-voltage 9V output with no drop-off throughout the discharge cycle
• Includes a rugged, reusable storage case with each 2-pack
• Compatible with most pedals, wireless packs, active instruments, and tuners

Great Fit For

• Guitarists and bassists running active pickups or active EQ systems
• Pedalboard builders who power individual effects with 9V snap connectors
• Players using clip-on wireless packs that require 9V batteries
• Musicians who want to reduce their disposable battery footprint
• Touring players and road techs who need dependable power on a tight schedule
• Home studio owners powering external preamps, tuners, or effects units

On Stage and In the Studio

The LED charge indicator takes the guesswork out of pre-show prep — a quick glance tells you whether you are good to go or need 30 minutes on the charger. The included storage case keeps both batteries and your USB-C cable organized in one place, so nothing gets lost between gigs. For active instruments with onboard preamps, the stable voltage output is a genuine upgrade over alkaline — no more tone shift as the battery drains through a long night.

One important note: some high-gain audio circuits with active pickups may exhibit a small amount of broadband noise with any lithium-ion rechargeable 9V — this is a known characteristic of the technology class and not specific to this product. Ernie Ball and Paleblue have designed and tested this battery to minimize that effect, but it is worth being aware of if your rig runs unusually sensitive circuitry. For the vast majority of pedals, wireless packs, tuners, and standard active electronics, these perform cleanly and consistently.
