About this replacement
Pure Woodland DAB Radio — 3.7V Li-ion Replacement Battery (LC18650-2S)
This is a 3.7V, 6700mAh Li-ion battery for the Pure Woodland DAB+ portable digital radio. It replaces part number LC18650-2S and fits the Woodland model (82300506). Install it when the original cell no longer holds charge or the radio shuts off unexpectedly during playback.
- Woodland and 82300506 compatibility: Both references point to the same hardware platform. The Woodland shares a single battery bay, connector pinout, and protection circuit interface — one cell covers both model identifiers.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a DAB receiver platform. The BMS responded correctly to protection circuit polling, and charge acceptance was consistent across multiple cycles with no cutoff errors under normal load.
- Post-swap station scan: After fitting this battery, run a full auto-scan before manual tuning. DAB station lists are held in volatile memory and are wiped on power loss. A fresh scan rebuilds the station index — manual tuning before scanning will return no results.
Radio cutting out mid-station at low battery
The DAB decoder in the Woodland needs stable voltage to reconstruct the OFDM stream. When the cell sags below the decoder's minimum input threshold, the stream breaks up before the battery protection circuit fully trips. You hear dropouts or complete cuts rather than a clean shutdown. Keeping the cell above 3.5V eliminates this — a degraded original cell that sags under RF load is the most common cause.
Reception noticeably worse than before battery failure
In weak signal areas, the Woodland's RF front end draws more current to maintain lock on the DAB multiplex. A battery that cannot sustain voltage under that increased draw causes the tuner to lose lock intermittently — this looks like poor reception but is actually a voltage supply problem. Confirm by testing in a strong-signal location: if reception is solid there, the issue is load-related voltage sag, not antenna or location. A fresh cell at full charge resolves this.
