BlackBerry Priv HUSV1 Replacement Battery 3.85V 3300mAh

BlackBerry Priv STV100 Series — 3.85V Li-Polymer Replacement Battery (HUSV1 / BAT-60122-003)

This is a 3.85V, 3300mAh lithium-polymer battery for the BlackBerry Priv smartphone. It fits the STV100-1, STV100-2 XLTE, and Venice variants. If your Priv shuts down unexpectedly, won't hold a charge, or won't power on at all, this cell replaces the original HUSV1.

• STV100-1, STV100-2 XLTE, and Venice compatibility: These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The HUSV1 cell specification — 3.85V nominal, 103.10 x 50.10 x 3.60mm — is consistent across the entire Priv lineup, so one cell covers all variants.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Priv STV100. The BMS accepted the cell without error flags, charge termination triggered correctly at 4.35V, and the fuel gauge IC updated without prompting a fault state.
• Fuel gauge recalibration on first cycle: After installation, disable fast charging and complete one full discharge-charge cycle at standard current. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes into an uncalibrated state — skipping this step causes erratic percentage readings.

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

This happens because the fuel gauge IC is still using the discharge curve from the old, degraded cell. When the new cell's actual open-circuit voltage drops below the IC's stored threshold — typically around 3.65V under modem or display load — the phone interprets it as critically low and shuts down before the real state of charge is exhausted. It is not a faulty cell. One complete discharge to automatic shutdown followed by an uninterrupted charge to 100% forces the coulomb counter to resync. After that cycle, shutdowns at 20–30% stop in the vast majority of cases.

Priv not powering on after the replacement battery sat in storage

Li-polymer cells self-discharge in storage. If the cell voltage dropped below 2.5V, the BMS enters a lockout state to prevent damage — the phone will show nothing when you press the power button. Connect the device to a wall charger, not a PC port, and leave it for 20–30 minutes without pressing any buttons. The charge IC will trickle current into the cell until voltage clears the BMS re-enable threshold, at which point the phone will boot or display a charging screen. If the screen stays dark after 45 minutes on the wall charger, check that the battery connector is fully seated.
