AeroScout T2-EB 3.6V Compatible Battery OM11560 2700mAh

AeroScout T2-EB Sensor Tag — 3.6V Li-SOCl2 Replacement Battery (OM11560)

This is a 3.6V, 2700mAh lithium-thionyl chloride cell built to the OM11560 specification. It fits the AeroScout T2-EB, T5, T5B, and T5C Sensor Tags — RTLS tracking devices used in clinical and healthcare environments. Swap it in when the original cell depletes and the tag stops reporting to the location system.

• T2-EB and T5-series tag compatibility: These sensor tags share the same 3.6V power rail, connector footprint, and BMS handshake protocol — the OM11560 cell satisfies all three. Mixing in a lower-voltage or different-chemistry cell will cause immediate BMS rejection or a persistent low-battery fault.
• Bench tested on actual hardware: We ran this cell through power-on initialisation on the T2-EB platform. The BMS accepted the cell without fault flags, completed its startup verification cycle, and the tag resumed active transmission on the RTLS network.
• Post-swap startup protocol: After installing the cell, let the device complete its full power-on self-test without interruption. The T-series BMS runs a chemistry verification check at boot — interrupting it before completion locks in a false battery fault that clears only on a forced full reboot.

Why the T2-EB triggers a low-battery alarm within minutes of a fresh cell install

The AeroScout RTLS firmware reads cell voltage against a stored OEM threshold calibrated to an aged Li-SOCl2 baseline. A new OM11560 cell sits at its nominal open-circuit voltage of 3.6V, but the BMS may interpret the initial voltage curve as out-of-spec until one full load cycle normalises the internal resistance profile. The alarm clears after the tag completes its first full active-transmit cycle. No firmware reset is needed — allow the device to run through one complete operational cycle before flagging the cell as defective.

T5-series tag will not power on after the replacement cell sat in storage

Li-SOCl2 cells self-discharge slowly in storage, and if the replacement cell dropped below approximately 3.2V before installation, the tag's BMS recovery threshold blocks startup entirely. This is a protective lockout — not a dead cell. Connect the tag to its reader or charging dock for a minimum 30-minute re-initialisation window before attempting to power on. If the open-circuit voltage reads above 3.2V on a multimeter and the tag still won't boot, force a hard reset by briefly removing and reinserting the cell, then allow the self-test to complete uninterrupted.
