Battery Replacement Service

All rechargeable batteries degrade over time. It's simple chemistry, not a fault. After hundreds of charge cycles your tVNS device may not hold a charge as long as it once did. Rather than replacing the whole device, our technicians can swap the internal battery and return it to you performing like new.

⚡
Like-new performance
A fresh cell restores the full charge capacity your device had on day one.
💰
Fraction of the cost
Much cheaper than buying a replacement device. Keep the hardware you know and trust.
⚒
Expert technicians
Serviced by the people who designed the device. No third-party guesswork.

Wish more manufacturers offered this

After 2 years of almost daily usage the device would barely last 20 minutes between charges. Swapping the battery was a no brainer. Service could have been faster as it took 3 weeks with shipping to UK and back.
