About this replacement
Jabra BT3030 / Street2 — 3.7V Li-Polymer Replacement Battery (AHB302323)
This 3.7V, 100mAh Li-Polymer cell replaces part number AHB302323 in the Jabra BT3030 and Street2 Bluetooth headsets. Both models run the same compact cell at identical voltage and connector spec. When the original cell degrades and talk time collapses, this swap restores the headset to working order.
- BT3030 and Street2 shared platform: Both headsets use the same 3.7V Li-Polymer cell, connector pinout, and BMS logic. A battery pulled from one will fit the other without modification.
- Bench tested on actual hardware: We cycled this cell through the BT3030's charging circuit and confirmed the BMS accepted the pack, reported charge state correctly, and held voltage through combined audio and Bluetooth radio draw.
- First-charge protocol for BT3030: Seat the headset in its charging cradle and let it complete a full charge cycle before making a call. The headset's firmware logs the new cell during that first cycle — skipping it causes the talk-time indicator to read inaccurately for the first several uses.
Why the BT3030 cuts out mid-call even with a charged battery
The BT3030 draws simultaneously from its audio amplifier and Bluetooth radio during a call. That combined load causes a brief voltage sag on a degraded or newly installed cell. If the cell voltage dips below the BMS cutoff threshold — typically around 3.0V under load — the headset shuts down even though the resting voltage reads fine. A fresh cell resolves the sag issue, but the first full charge cycle must complete before the BMS calibrates its cutoff accurately against the new cell's capacity curve.
Base station shows full charge but headset dies after a few minutes
A replacement cell ships at storage voltage, usually between 3.6V and 3.8V. The charging cradle may interpret this as a near-full cell and terminate the charge cycle early. The headset then starts from a partially charged state and cuts off quickly under load. Place the headset back in the cradle, leave it undisturbed for a complete charge cycle, and confirm the indicator shows a full charge before use. After that first full cycle the charging circuit reads the cell correctly.
