Are CELLONIC batteries safe?

Yes, we use premium-grade cells with built-in protection against over-voltage, short-circuits and overheating. Every battery pack is tested several times before it ships, ensuring reliable, smooth performance.

Is this battery compatible with my device?

Match the model or part-number in our “Compatible with” list. If your device appears there, the battery fits perfectly—no adapters needed.

Can I replace the battery myself?

Depending on the battery type, it will either simply fit in or require only basic tools and care. If the original is glued or soldered in, or you're not confident in changing it yourself, we recommend using a professional to avoid any damage.

Can I use a higher- or lower-capacity battery than the original that came with my device?

Yes - as long as voltage and model compatibility match. Higher capacities deliver longer runtimes, lower capacities works the same but may run shorter.

Why choose CELLONIC over original, branded batteries?

CELLONIC replacement batteries offer reliable performance at a lower cost. Our batteries meet the highest standards, ensuring safe, long-lasting power, the same if not better than your original.

Battery Replacement for B&O H9i headphones

Took seconds to fit, charged up and worked fine ... I guess we'll only know if it was worth the +£30 saving on an official B&O battery if it's still working in a couple of years from now!
