It replaces OEM part numbers BP-R1EU, BP-R1, BP-R2, BP-R5, and BP-R12EU. When the original pack no longer holds a charge, this restores full portable operation to your DAB receiver.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR1 \/ R2 platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and 7.2V supply rail. The DAB decoder and RF front-end both draw from the same pack, so voltage and cell count must match exactly — this battery does.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a DAB receiver load. The BMS held voltage stable across both the RF stage and the digital decoder without dropout. Cell balance stayed consistent across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStation list recovery after swap:\u003c\/strong\u003e\n    After fitting this battery, let the radio run a full auto-scan before manually selecting stations. DAB station lists are stored in volatile memory and are wiped on power loss — a complete scan rebuilds the full station index correctly.\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 in the R1 and R2 requires a stable, uninterrupted voltage supply to decode the OFDM stream. When cell voltage sags below roughly 6.0V under load, the decoder loses sync and the audio drops out — this is a voltage floor issue, not a signal issue. A fresh, fully charged pack eliminates the sag. If cutouts persist with a new battery, check that the radio's battery contacts are clean and making firm contact with the pack terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReception noticeably worse than with the original battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RF front-end in a DAB radio draws more current when it's hunting for a weak multiplex signal. If the battery voltage is marginal, the radio can't sustain full RF output power and signal acquisition degrades. This appears as poor reception or frequent re-buffering even in areas where the radio previously performed well. Charge the new pack fully before testing reception — Ni-MH cells need at least one complete charge cycle to reach rated capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360084951130,"sku":"BWCS-TPM002SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360084983898,"sku":"BWCS-TPM002SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360085016666,"sku":"BWCS-TPM002SL-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TPM002SL-1.webp?v=1778610878","url":"https:\/\/batteryweb.com\/products\/teac-r1-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
