Ernie Ball USB-C Rechargeable Battery AA (4-Pack)

The Ernie Ball USB-C Rechargeable Battery AA (4-pack) gives you a smarter way to power your gear. Each battery uses lithium-ion chemistry. That means you get steady power until the next charge. There’s a small USB-C port on every battery, so you don’t need a special charger or a dock. Just use a USB-C cable, and you’re good. Charging all four takes about two hours. LED lights show when they’re full. The batteries come in a tough case you can throw in your gig bag. You’ll get around 1,000 charges from each one, so you don’t have to buy new batteries every month. These are made for musicians who use wireless mics, effects pedals, or home gear that eats up AAs.

Charge, Reuse, and Save With Ernie Ball Batteries

Anyone who plays a lot, records at home, or even runs a wireless mouse can use these. If you rehearse with a pedalboard, use a wireless pack on stage, or just want to stop tossing out dead batteries, this pack helps. The USB-C port makes it easy to charge at school, home, or on tour. A storage case keeps the set organized in your backpack or desk. These batteries save money and reduce waste. You stay powered up for practice, gigs, or long days of school projects—no last-minute trips to buy more AAs.
