Geneva WorldRadio BPS454094P Replacement Battery 3.7V 2100mAh

Geneva WorldRadio — 3.7V Li-Polymer Replacement Battery (BPS454094P)

This 3.7V, 2100mAh lithium-polymer battery replaces the OEM pack in the Geneva WorldRadio portable DAB digital radio receiver. Part number BPS454094P. It matches the original cell dimensions at 95.94 × 39.60 × 4.50mm, fitting the internal battery bay without modification.

• WorldRadio platform fit: The Geneva WorldRadio uses a flat Li-Polymer cell on a 3.7V rail with a dedicated BMS connector. This cell matches that rail, connector pinout, and form factor — the radio's charge circuit communicates directly with the pack's protection board during both charge and discharge cycles.
• Bench tested on actual hardware: We cycled this cell through the WorldRadio's charge circuit and confirmed the BMS handshake completes correctly. The protection board tripped at the expected low-voltage cutoff and recovered cleanly on reconnection — no faults logged.
• Post-swap station scan: After fitting a new battery, run a full auto-scan before manual tuning. The WorldRadio stores its DAB station list in volatile memory — a power interruption wipes it. Auto-scan rebuilds the complete multiplex list from scratch, which manual tuning alone will not restore.

Radio cutting out mid-station at low battery

DAB decoding is more voltage-sensitive than FM. The WorldRadio's decoder chip needs a stable voltage to reassemble the OFDM data stream — when the cell sags below the decoder's operating threshold, the stream errors out and the audio drops entirely, often before the battery indicator shows empty. This is not a reception problem; it is a voltage floor problem. A new cell at full charge eliminates sag-induced cutouts by maintaining voltage above that threshold for longer across the discharge curve.

Reception noticeably worse than it was on the old battery

In weak DAB signal areas, the WorldRadio increases RF search power to lock onto multiplexes. A degraded or deeply discharged cell cannot sustain the voltage needed for full RF output, so the radio drops to a lower power state and loses marginal stations. This looks like an aerial or location problem but is actually a supply issue. Charge the new cell fully before the first use — check that the radio's battery indicator reads full before testing reception in a weak-signal location.
