Replacement Battery for ZTE Nubia Z7 Max

This Cameron & Co DS-CS-ZNX505SL is a direct replacement battery designed for the ZTE Nubia Z7 Max and Nubia Z7 Max Dual SIM NX505J. It matches the original Li3803T43P3hB34243 and Li3830T43P3hB34243i part numbers for 100% OEM compatibility. The unit ships brand new in black.

Capacity and Headroom

The lithium-polymer cell delivers 3.8V and 3100mAh, providing 11.78Wh of energy. This capacity restores the original runtime for daily tasks and moderate use. Heavy workloads such as continuous navigation or video streaming will deplete the charge faster, requiring a mid-day top-up.

Physical Fit Constraint

The battery measures 113.10 x 41.24 x 4.00 mm, a specific footprint that must match the phone's internal cavity exactly. Builders repairing other ZTE models or devices with different battery dimensions cannot use this part.
