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.

Replacement for my MIFI

Bought this to replace the battery in my TP-LINK Mifi which I have had for 5 years. The original battery has been excellent but very recently had reduced in performance due to age, so being able to acquire a replacement extends the life of the Mifi

Does not fit, battery far to small for my TP Link.

Firstly, the battery was smaller than the original so fit was no good, when trying to return the batteryIt was not accepted by the post office. To send by DHL it was going to cost more to send than the battery costIn delivery, packaging and fuel costs to get it to the closest depot. As battery didnot fit was also unable to find out if the battery worked or not. Do not buy from this supplier.
