HP Veer BP3 Replacement Battery 3.7V 920mAh

HP Veer 4G / P160U — 3.7V Li-ion Replacement Battery (BP3 / 157-10151-00)

This is a 3.7V 920mAh Li-ion battery for the HP Veer and Veer 4G smartphones (models P160U and P160UEU). It replaces OEM part numbers BP3 and 157-10151-00. The Veer's compact chassis leaves almost no room for a swollen or degraded cell — swap it before the original starts pressing against the screen assembly.

• Veer and Veer 4G compatibility: The P160U and P160UEU share the same battery bay dimensions (43.80 × 34.50 × 5.50mm), voltage rail, and connector pinout — one cell covers both variants without modification.
• Bench tested on actual hardware: We ran this cell through charge-discharge cycles on the Veer platform. The BMS handshake completed on the first cycle, charge IC accepted the cell without error flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first use: After fitting this cell, disable fast charging and let the phone complete one full discharge down to auto-shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell's discharge curve before any high-current charging pushes into an uncalibrated state.

Sudden shutdown at 20–30% on the HP Veer after a cell swap

The Veer's fuel gauge IC stores a discharge curve calibrated to the original cell. A new cell with different internal resistance causes the IC to misread remaining capacity. When the modem transmits or the screen brightness peaks, actual cell voltage drops faster than the IC expects and the BMS cuts power abruptly — often between 20–30% reported charge. One complete discharge-recharge cycle resets the reference data. After that cycle, the percentage reading stabilises and early shutdowns stop.

HP Veer won't power on after sitting in storage

Li-ion cells stored at low charge self-discharge over weeks. If the cell drops below 2.5V, the BMS enters lockout mode and blocks current flow entirely — the phone shows nothing when you press power or connect a charger. Connect the Veer to a low-current USB source (a standard 5V 500mA port, not a fast charger) and leave it for 20–30 minutes without pressing anything. Once the cell climbs above 2.8V, the BMS releases and normal charging resumes. If the screen still shows no response after an hour, check the charging port contacts before concluding the cell is faulty.
