HTC Droid Incredible 2 ADR6410 Replacement Battery 3.7V 1300mAh

Verizon ADR6410 / Droid Incredible 2 — 3.7V Li-ion Replacement Battery (35H00180-02M)

This is a 3.7V, 1300mAh Li-ion cell for the HTC Droid Incredible 2, sold under Verizon model numbers ADR6410, ADR6410L, and ADR6410LVW. It replaces OEM parts 35H00180-02M, BTR6410B, 35H00184-01M, and 35H00181-01M. The cell fits the standard battery bay and connects to the device's charge IC and fuel gauge via the original contact plate.

• ADR6410 variant coverage: The ADR6410, ADR6410L, and ADR6410LVW share the same battery bay dimensions, voltage rail, and contact layout. All three pull from the same OEM cell spec, so one replacement covers every variant in that lineup without modification.
• Bench tested on actual hardware: We cycled this cell through a full discharge-charge sequence while monitoring BMS communication with the charge IC. The protection circuit tripped correctly at the low-voltage threshold and accepted charge current without error flags on reconnection.
• Fuel gauge recalibration on first use: On first install, run one full discharge down to automatic shutoff, then charge uninterrupted to 100% before use. The Droid Incredible 2's coulomb counter recalibrates its state-of-charge model against the new cell's actual discharge curve during that first cycle — skipping it causes percentage drift from the start.

Sudden shutdown at 20–30% on the Droid Incredible 2

This phone's Snapdragon S3 chipset draws a burst of current when the modem switches between 3G and CDMA bands or when the screen wakes at full brightness. An aged or uncalibrated cell cannot hold voltage under that load spike, so the battery voltage drops below the BMS cutoff threshold even though the fuel gauge still shows charge remaining. The result is a hard shutdown despite a non-zero percentage reading. The fix is a full calibration cycle on the new cell — one complete discharge to shutoff and a full uninterrupted charge — so the coulomb counter maps the cell's actual voltage-to-capacity curve before normal use.

Phone reports wrong battery percentage after cell swap

The Droid Incredible 2 uses a fuel gauge IC that tracks charge using a coulomb counter trained on the previous cell's impedance and discharge profile. When a new cell goes in, that stored model no longer matches the physical cell, so the reported percentage drifts — often reading full when the cell is not, or dropping suddenly mid-use. This is not a fault in the replacement cell. One complete discharge-to-shutoff followed by a full uninterrupted charge forces the fuel gauge IC to rebuild its model against the new cell. After that cycle, percentage reporting stabilises at normal accuracy.
