Verizon Touch XV6900 Compatible Battery 3.7V 1100mAh

Verizon Touch XV6900 — 3.7V Li-ion Replacement Battery (ELF0160)

This 3.7V, 1100mAh Li-ion cell is a direct swap for the original battery in the Verizon Touch XV6900 Windows Mobile smartphone. It matches the OEM voltage rail and physical dimensions (51.53 × 37.36 × 5.35mm), so it seats correctly in the battery bay without modification. Capacity figure is sourced from the product data — 4.07Wh total energy.

• Touch XV6900 compatibility: The XV6900 uses a single-cell Li-ion pack with a three-contact connector carrying voltage, ground, and a thermistor line. This cell matches that connector pinout and the 3.7V nominal rail the device's power management IC expects. Cross-reference OEM part numbers ELF0160, 35H00095-00M, or FFEA175B009951 to confirm fit before installing.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the XV6900 platform. The BMS held charge termination at 4.2V and the protection circuit tripped correctly on a simulated short — no thermal runaway, no false cutoff under screen-on load.
• Fuel gauge recalibration after swap: After installing this cell, run one full discharge to near-empty, then charge uninterrupted to 100% before normal use. The XV6900's fuel gauge IC was calibrated to the old cell's discharge curve — skipping this step causes the percentage counter to read inaccurately from day one.

Sudden shutdown at 20–30% on the XV6900 after a cell swap

The XV6900's power management IC monitors cell voltage in real time. A new Li-ion cell has a steeper voltage drop curve at low state-of-charge than a well-aged original. When the modem transmits or the backlight fires at full brightness, instantaneous current draw pulls the cell voltage below the cutoff threshold — even if the fuel gauge still shows 20–30%. This is a voltage cliff, not a capacity defect. One full discharge-charge calibration cycle flattens the discrepancy between the fuel gauge estimate and actual cell voltage, and the shutdowns stop.

Device won't power on after sitting in storage with a dead battery

If the XV6900 was stored discharged for weeks or months, the replacement battery may have also self-discharged below 2.5V per cell during transit or warehouse storage. The BMS locks out charge acceptance below that threshold as a safety measure — the phone shows nothing when connected to a charger. Connect the phone to a wall adapter (not a PC USB port) and leave it for 20–30 minutes without pressing the power button. The charge IC on the phone applies a trickle current to recover the cell above 2.8V, at which point the BMS releases and normal charging resumes.
