ZTE N760 Li3715T42P3h415266 Replacement Battery 3.7V 1500mAh

ZTE N760 / Blade Plus / V881 Series — 3.7V Li-ion Replacement Battery (Li3715T42P3h415266)

This is a 3.7V, 1500mAh Li-ion cell built to the OEM spec for the ZTE N760, Z900, Blade Plus, V881, and compatible variants. It replaces part number Li3715T42P3h415266. If your ZTE handset no longer holds a charge or shuts down unexpectedly, this cell slots into the same footprint as the original at 41 × 51 × 6mm.

• N760, Z900, Blade Plus, V881 compatibility: These models share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS communication lines are also identical across the group, so the fuel gauge IC on the motherboard reads the new cell without requiring a hardware workaround.
• Bench tested on actual hardware: We cycled this cell on the N760 platform and monitored BMS cutoff behaviour at both ends of the voltage curve. The protection circuit tripped correctly at the low-voltage threshold — no pass-through to the motherboard rail.
• First-cycle fast charge protocol: On first use after installation, disable fast charging for one complete discharge-charge cycle. The fuel gauge IC on these ZTE models calibrates its coulomb counter against the new cell's discharge curve — running high current into an uncalibrated cell skews the percentage readings from the first charge onward.

Sudden shutdown at 20–30% on the ZTE N760 after a cell swap

The N760's fuel gauge IC builds a discharge model from the previous cell's impedance profile. A new cell has a different internal resistance, so the voltage cliff — where cell voltage collapses under modem or screen load — hits at a different state of charge than the IC expects. The phone reads 25% remaining, the cell voltage drops below the BMS trip point under load, and the device shuts off. Running two full discharge-charge cycles without fast charging lets the coulomb counter rebuild its model against the actual new cell curve. After that, the reported percentage and the real cutoff point realign.

Phone won't power on after the replacement cell sat in storage

Li-ion cells self-discharge in storage. If this battery shipped or was stored for several months, the cell voltage may have dropped below 2.5V — the threshold where the BMS locks out to prevent damage. The phone will show nothing when you press power. Connect the device to a wall charger, not a PC USB port, and leave it for 15–20 minutes before attempting to power on. Most ZTE BMS circuits will begin a trickle pre-charge recovery once they detect a valid charge source above the lockout floor; the phone should show a charging indicator once the cell climbs back above 3.0V.
