It matches OEM part number NA2000D08C101 and slots directly into the DAB 20 battery compartment. Voltage and capacity are matched to the original specification so the DAB decoder and RF front-end receive the correct power supply.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDual DAB 20 fit:\u003c\/strong\u003e\n    The DAB 20 draws power through a fixed-voltage rail shared by the RF tuner and digital decoder. Both circuits require 8.4V nominal from a Ni-MH cell stack — swapping chemistry or voltage causes the decoder to drop the stream or fail to power on entirely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the DAB 20 platform. The BMS held stable voltage through the tuner lock sequence and maintained output above the DAB decoder's minimum threshold across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStation list rebuild after swap:\u003c\/strong\u003e\n    After fitting this battery, run a full auto-scan before manual tuning. The DAB 20 stores its station list in volatile memory — a power interruption from a flat or removed battery wipes it. Auto-scan rebuilds the complete multiplex list for your region.\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 on the DAB 20\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DAB 20's decoder chip needs a stable voltage above roughly 6V to maintain its stream lock. As a Ni-MH pack discharges, cell voltage drops gradually — but under RF load, instantaneous sags can push the supply below that threshold. When that happens, the decoder loses frame sync and the audio drops out, even if the battery indicator still shows charge remaining. A fresh, fully charged pack eliminates the sag margin that causes mid-stream dropouts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDAB 20 reception noticeably worse after fitting a replacement battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RF front-end in the DAB 20 scales its amplifier output based on available supply voltage. A battery that reads 8.4V nominal but cannot sustain that under load delivers less headroom to the tuner, which reduces signal sensitivity. This is most obvious in fringe coverage areas where the radio needs maximum RF gain to hold a multiplex. Check the pack is fully charged — a resting voltage below 8.0V on a Ni-MH pack indicates incomplete charging; reconnect to the charger until the charge cycle completes fully.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360100581466,"sku":"BWCS-DVP200SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360100614234,"sku":"BWCS-DVP200SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360100647002,"sku":"BWCS-DVP200SL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DVP200SL-1.webp?v=1778610859","url":"https:\/\/batteryweb.com\/products\/dual-dab-20-replacement-battery-84v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
