It replaces OEM part numbers FNB-10, FNB-10H, FNB-12, FNB-12H, FNB-14, FNB-14H, FNB-17, and FNB-17H. Physical dimensions are 81 × 54 × 33mm — the same footprint as the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFT-23R \/ FT-33R \/ FT-73R platform fit:\u003c\/strong\u003e\n    These models share a common battery bay and contact arrangement across the FNB-10 through FNB-17 family. The voltage rail is consistent at 12V and the connector pin-out is identical — no adapters needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge-discharge cycle on the FT-23R platform. The BMS accepted the charge handshake on first insertion, and TX current draw during sustained PTT held steady without triggering overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle contact check on the Yaesu dock:\u003c\/strong\u003e\n    If the charger shows a fault indicator on first insertion, remove the battery and wipe the gold contact strip with a dry cloth before reseating. The Yaesu dock requires a clean contact cycle to complete the BMS handshake — this is not a defective pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the FT-23R cuts out mid-transmission on a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.0–1.1V per cell, well below the 1.2V nominal. On a 10-cell 12V pack, that puts the resting voltage under 11V at first use. The FT-23R's transmit circuit draws a sharp current spike the moment PTT is pressed. If the cells haven't completed a conditioning charge cycle, the BMS reads that spike as an overcurrent event and cuts output. Run one full charge before the first transmission — not a partial top-up, a complete charge cycle to termination.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe FT-23R uses a simple voltage-threshold bar indicator — each bar corresponds to a specific voltage window. A new Ni-MH pack often reads one bar low immediately after its first charge because the cells haven't fully accepted capacity yet. This is a cell conditioning issue, not a faulty battery. Run two full charge-discharge cycles and the resting voltage will settle above the threshold for the top bar — typically above 12.4V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426350399578,"sku":"BWCS-FNB17TW-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426350432346,"sku":"BWCS-FNB17TW-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426350465114,"sku":"BWCS-FNB17TW-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNB17TW-1.webp?v=1779930807","url":"https:\/\/batteryweb.com\/products\/yaesu-ft-23r-replacement-battery-12v-1000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
