This Estry lithium battery replaces the original Li3945T44P8H906455 pack in the Nubia Red Magic 6 NX669J. It supplies a nominal 3.85V and a rated capacity of 5000mAh.

The cell matches the OEM footprint, so it seats in the existing battery cavity without adapters or case modification. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit events. No external charger or additional wiring is required; the phone’s own management system handles balancing and fuel-gauge reporting.
Steady Output Through Extended Sessions
Under continuous load the protection circuit maintains stable voltage delivery while the 4850mAh typical capacity sustains runtime. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming consistent manufacturing quality.
