Quality premium

Premium quality guarantees good charging stability, balanced autonomy and correct fit inside the terminal housing. It is intended for professional repairs where the goal is to restore the power performance of the Vivo NEX, Vivo NEX S or Vivo NEX A without modifying the normal behaviour of the device. Its commercial capacity of 4000mAh and approximate voltage of 3.85V allow a suitable replacement when the battery presents exhausted cycles, unexpected shutdowns, irregular charging or swelling. We recommend checking the reference printed on the removed battery, performing a controlled first charge and verifying consumption, temperature and percentage before final closure. Available for immediate shipping from Spain.

Installation tips

Disconnect the battery before handling any internal flex.

Use ESD protection throughout the process.

Test the battery cold before closing the terminal.

Check that the connector fits without pressure or twisting.

Perform a controlled initial charge and verify temperature.

Replace internal adhesives if they have lost fixation.

Calibrate the battery percentage after installation.

Notice

Before installation, always check the battery installed in the terminal. Some Vivo models may have regional variants or different internal references depending on the marketing area. Always compare the reference printed on the factory-installed battery, the technical model of the device, the flex and the connector position before removing adhesives or closing the device. This reference is intended for 4000mAh Vivo NEX models; it must not be confused with Vivo NEX Dual Display V1821A V1821T or 1813, which uses a 3500mAh battery.
