HTC ADR6410 Droid Incredible Replacement Battery 3.7V 1300mAh

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

This is a 3.7V, 1300mAh Li-ion replacement battery for the HTC Droid Incredible ADR6410 and ADR6410L series smartphones. It fits devices where the original cell has degraded and can no longer hold a usable charge. OEM part numbers covered include 35H00180-02M, BTR6410B, 35H00184-01M, and 35H00181-01M.

• ADR6410, ADR6410L, ADR6410LVW, and Droid Incredible 4G LTE: These variants share the same 3.7V battery bay, connector pinout, and BMS communication protocol, which is why one cell fits the full range. Swapping between these models does not require any firmware or hardware change.
• Bench tested on actual hardware: We cycled this cell on an ADR6410 unit, confirmed the BMS accepted the charge handshake without error flags, and verified the protection circuit tripped correctly at undervoltage. Charge acceptance was consistent across three full cycles.
• Fuel gauge recalibration on first use: After installing a new cell, disable fast charging for the first complete discharge-charge cycle. The phone's fuel gauge IC is calibrated to the old cell's discharge curve — running one slow cycle lets it map the new cell accurately before high-current charging begins.

Sudden shutdown at 20–30% on the ADR6410 after a cell swap

The ADR6410's fuel gauge IC uses a coulomb counter that was calibrated against the original cell's internal resistance and discharge curve. A new cell has different impedance characteristics, so the reported state of charge drifts from the real voltage. When the modem transmits or the screen peaks in brightness, the actual cell voltage drops below the 3.4V cutoff threshold while the UI still shows 25%. The phone shuts down to protect the cell. One full slow discharge-charge cycle re-anchors the coulomb counter and eliminates these early cutoffs.

Phone not powering on after the replacement battery sat in storage

Li-ion cells self-discharge during storage, and if a replacement cell drops below approximately 2.5V, the BMS latches into lockout mode and blocks all charge current to prevent plating. The ADR6410 will show nothing on screen and may not respond to the charger. Connect the phone to a wall charger — not a PC USB port — and leave it for 20 to 30 minutes without pressing the power button. Most BMS circuits will accept a trickle recovery current at this stage and release the lockout once the cell climbs back above 2.9V.
