Ingenico RoadRunners Evolution 1D Replacement Battery 3.7V 2400mAh

Ingenico RoadRunners Evolution 1D — 3.7V Li-ion Replacement Battery (B25000005)

This 3.7V, 2400mAh Li-ion cell replaces the original pack in the Ingenico RoadRunners Evolution 1D and BRR-L Evolution handheld barcode scanners. It fits the YYS1-1056730 and BRR-L platform variants that share the same form factor and connector. OEM part numbers B25000005 and BD1227 both cross to this replacement.

• RoadRunners Evolution platform fit: The 1D, BRR-L Evolution, and YYS1-1056730 variants all run the same 3.7V rail with an identical connector and BMS handshake protocol. One cell covers the full group — no pinout differences between listed models.
• Bench tested on actual hardware: We cycled this pack through scan-burst sequences and wireless polling intervals on the bench. The BMS held steady through rapid trigger pulls and sustained no-load standby without dropping below the low-voltage cutoff threshold.
• First-shift preparation: After installing the new pack, seat the scanner in its cradle for a complete charge cycle before the first pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum charge, and a partially charged cell can trip the BMS on the first burst — a full cradle charge prevents that.

Cradle showing a charging error on a new pack

The RoadRunners Evolution cradle reads pack state through gold pogo contacts on the base of the scanner. Oxidation or residue on those contacts raises resistance enough for the dock to flag a fault before charging begins. This is not a cell defect — it is a contact issue between the dock and the pack. Wipe the contacts on both the scanner and the cradle with a dry lint-free cloth, reseat firmly, and the error clears in most cases.

Scanner dropping wireless connection during a rapid scan burst

The RoadRunners Evolution 1D draws simultaneously from its radio module and the scan trigger during a burst sequence. That combined inrush causes a brief voltage sag on a cell that is low or degraded. When the sag crosses the BMS cutoff threshold, the radio drops first — the wireless stack loses power before the display goes dark. If reconnection happens automatically after a pause, the cell voltage is marginal. Charge to full and if the drop recurs on a charged pack, the cell capacity has faded and replacement is the correct fix.
