It delivers the correct voltage rail and connector footprint for direct dock charging. Capacity is rated at 12.96Wh as supplied.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFNB67-compatible platform fit:\u003c\/strong\u003e\n    Radios in this family share a common 7.2V Ni-MH voltage rail, matching connector geometry, and the same contact pin layout — that is why this pack works across the compatible model range without adapter modifications.\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 transmit loads on the bench. The BMS handled PTT transmit current spikes without tripping, and the dock accepted the handshake cleanly after a standard first-charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the dock:\u003c\/strong\u003e\n    If the charger LED shows a fault on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. Ni-MH packs ship at storage voltage — the dock needs a clean contact cycle to begin the initial charge sequence correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy a new BL168 shows fewer signal bars than expected on first use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRetevis portables use voltage-threshold bar indicators — the radio reads pack voltage and maps it to bars. A new Ni-MH pack ships at storage voltage, typically well below its fully charged 8.4V peak. At storage voltage, the indicator will show one or two bars even with a brand-new pack installed. Run a full charge cycle before drawing any conclusions about pack condition. After a complete charge, bar display should reflect actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cuts out or drops TX power mid-transmission on the BL168\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained RF transmission draws significantly more current than standby or receive modes. If the pack voltage sags below the radio's TX threshold during a long transmission, the unit will cut output or drop to reduced power to protect the circuit. This is more pronounced on a partially discharged pack. Charge the BL168 fully before a heavy-use shift, and confirm resting voltage reads at or near 8.4V before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426351939674,"sku":"BWCS-FNB67TW-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426351972442,"sku":"BWCS-FNB67TW-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426352005210,"sku":"BWCS-FNB67TW-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNB67TW-1.webp?v=1779930807","url":"https:\/\/batteryweb.com\/products\/retevis-replacement-battery-72v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
