Dual DAB Pocket Radio 5 Compatible Battery 3.7V 1350mAh

Dual DAB Pocket Radio 5 — 3.7V Li-Polymer Replacement Battery (10269)

This is a 3.7V, 1350mAh (5Wh) Li-Polymer battery for the Dual DAB Pocket Radio 5. It replaces the original internal cell that degrades over charge cycles, restoring the radio to normal operation. Dimensions are 54.40 × 42.00 × 4.80mm — confirm these against your existing cell before fitting.

• DAB Pocket Radio 5 fitment: The DAB Pocket Radio 5 uses a slim Li-Polymer cell at this exact footprint. The BMS in the radio manages charge termination and low-voltage cutoff — this cell meets the voltage and size requirements for that circuit to function correctly.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS accepted charge without fault flags, held voltage through the DAB decoder's draw, and cut off cleanly at the low-voltage threshold.
• Post-install station scan: After fitting this battery, run a full auto-scan before manually tuning stations. DAB station lists are stored in volatile memory and are lost when power is interrupted. A fresh scan rebuilds the list correctly — manual tuning before scanning will miss stations.

Radio cutting out mid-station at low battery

The DAB decoder in the Pocket Radio 5 needs a stable voltage to maintain stream synchronisation. As the cell discharges toward 3.4V, voltage sags under the decoder's draw and the stream drops out — the radio may cut audio, lose the station lock, or restart. This happens more often in areas with weaker DAB signal because the RF front end draws harder to maintain reception. Fitting a fresh cell with full charge eliminates sag-driven dropouts.

Reception noticeably worse than it was on the original battery

Poor reception after a battery swap usually means the new cell's resting voltage is low from storage — not a fault with the radio or antenna. The RF amplifier stage requires the cell to be above approximately 3.6V to output full signal-search power. Charge the new battery fully before judging reception quality. If weak signal areas still cause dropout, move to a window or higher floor — DAB signal strength is location-dependent, not a battery issue.
