Vocollect Talkman T2 7.4V Compatible Battery 730025 3400mAh

Vocollect Talkman T2 / T2X — 7.4V Li-ion Replacement Battery (730025)

This 7.4V 3400mAh Li-ion pack replaces OEM part numbers 730025, 730021, BT-602-1, and CWI26591 in the Vocollect Talkman T2 and T2X voice-directed picking terminals. These devices run warehouse pick-and-pack operations via voice commands, so a dead or degraded cell directly stops a worker mid-shift. Voltage and capacity match the original spec exactly.

• T2 and T2X compatibility: Both models run the same 7.4V power rail, use the same physical connector, and communicate with the same BMS handshake protocol — one pack covers either unit without modification or firmware changes.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a T2 unit, confirmed the BMS handshake completed correctly, and verified the voice prompt and scan trigger responded without fault codes or mid-cycle cutoffs.
• First-use charging on the T2 dock: After installing, seat the pack in the Talkman cradle and run a full charge cycle before the first shift. Scan trigger inrush current is highest when the cell is near minimum — starting from a full charge prevents false BMS trips on that first pick run.

Cradle showing a charging error on a new pack

The Talkman dock reads pack state through pogo-pin contacts on the battery base. If those contacts are dirty or partially seated, the dock registers a communication fault and flags a charging error even though the pack itself is fine. Wipe the gold contacts on both the pack and the dock with a dry cloth, then firmly reseat the battery until it clicks. If the error clears, the issue was contact resistance — not a faulty cell.

Scanner losing wireless connection during rapid scan bursts

The T2 draws current simultaneously from the wireless radio and the imager during a fast scan sequence. Combined inrush from both loads can pull the cell voltage down sharply, and a worn or low-charge pack may drop below the BMS floor, causing the radio to drop its network association. This looks like a wireless fault but is actually a voltage sag event. Keep the pack above 7.0V during shift — if dropout persists on a fully charged new pack, check the dock contacts for poor charge transfer.
