It fits the Pure Digital Pocket DAB1500, TalkSport, and Pocketdab 1500 portable DAB digital radio receivers. When the original cell degrades and the radio stops holding charge, this swap restores the unit to full portable operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDAB1500 \/ TalkSport \/ Pocketdab 1500 platform:\u003c\/strong\u003e\n    All three models share the same PCB layout, LP37 connector pinout, and BMS handshake protocol. A single cell covers the entire range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the DAB1500 platform. The BMS accepted the charge handshake cleanly, reached full cell voltage without fault flags, and held voltage stable under the DAB decoder's draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install station scan:\u003c\/strong\u003e\n    After fitting a new battery, run a full auto-scan from the radio's menu before attempting manual tuning. DAB station lists are stored in volatile memory and are wiped on power loss. The auto-scan rebuilds the full station list — manual tuning before this step will find nothing.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cutting out mid-station at low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DAB decoder inside the Pocket DAB1500 requires a stable voltage rail to process the OFDM stream. When cell voltage sags below roughly 3.4V under load, the decoder loses lock on the multiplex and the audio drops. This is not a reception problem — it happens even with a strong signal. The fix is a cell replacement: a degraded battery that reads 3.6V at rest can still sag under the decoder's draw and trigger dropouts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReception noticeably worse on new battery than expected\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePoor DAB reception after a battery swap is usually a voltage floor issue on the old cell, not a problem with the new one. The DAB1500 boosts RF sensitivity and scan power when signal is weak, and that draw needs the battery above its minimum operating voltage. If reception seems worse than it should be, check that the new cell has completed its first full charge cycle — partially charged cells can still undervolt the RF front end during a signal search. Once fully charged, run a fresh auto-scan with the radio positioned near a window to get the strongest possible signal for the initial station build.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360104513626,"sku":"BWCS-PB1500SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360104546394,"sku":"BWCS-PB1500SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360104579162,"sku":"BWCS-PB1500SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PB1500SL-1.webp?v=1778610859","url":"https:\/\/batteryweb.com\/products\/pure-digital-pocket-dab1500-replacement-battery-37v-1800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
