INSIGNIA NS-HD01A DAB Radio Replacement Battery 3.7V 900mAh

INSGINIA NS-HD01A — 3.7V Li-ion Replacement Battery (ICP463450A 1S1PMXZ)

This 3.7V 900mAh Li-ion battery replaces the original cell in the INSGINIA NS-HD01A portable DAB digital radio. It fits the slim handheld chassis directly, using the same ICP463450A 1S1PMXZ cell format at 51.80 × 34.00 × 4.70mm. Voltage and capacity match OEM spec — no modification needed.

• NS-HD01A platform fit: The NS-HD01A runs a single-cell 3.7V Li-ion architecture with a compact protection circuit matched to low-current DAB decoder draw. This cell uses the same footprint and connector orientation as the factory unit, so the BMS handshake completes normally on first power-up.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the NS-HD01A board. The protection circuit responded correctly to charge termination, and the DAB decoder held lock without voltage sag interrupting the stream decode.
• Post-swap station scan: After any power interruption — including a battery swap — the NS-HD01A loses its stored station list from volatile memory. Once the new battery is seated and the radio powers on, run a full auto-scan before attempting manual tuning. This lets the radio rebuild its DAB station index from scratch and prevents blank or frozen station entries.

Radio cutting out mid-station at low battery

DAB decoding is computationally intensive compared to FM. The NS-HD01A's decoder chip requires a stable voltage above approximately 3.2V to maintain stream lock. When a degraded or discharged cell sags under the RF and decode load, the decoder drops the multiplex and the audio cuts out — even if the radio appears to still be on. The fix is straightforward: a cell that holds above 3.2V under load restores uninterrupted decode. Check that the replacement cell reads at least 3.6V open-circuit before installing.

Reception noticeably worse after fitting a new battery

Poor post-swap reception is usually a station list problem, not an antenna or RF problem. If the auto-scan was skipped after the battery change, the radio may be trying to tune stored frequencies that no longer have valid multiplex data — showing weak or no signal on channels that would otherwise lock cleanly. Run a full auto-scan from the menu to force the NS-HD01A to re-acquire all active DAB blocks in range. If signal remains weak after rescanning, the issue is local DAB coverage, not the battery.
