It fits the F1000, F1000D, F1000S, and F1000T, along with 22 additional F-series variants sharing the same battery bay and connector. Voltage and capacity match OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF1000 series platform fit:\u003c\/strong\u003e\n    All listed F-series models run the same 7.4V two-cell Li-ion architecture with an identical battery bay, latch geometry, and BMS handshake protocol. One battery covers the full platform without modification.\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 cycle and PTT load simulation on the F1000 platform. The BMS accepted the charger handshake on first insertion, held voltage under transmit load, and did not trip overcurrent protection during keying.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on initial seating, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The F1000 dock requires a clean contact cycle to complete the BMS handshake before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the F1000 drops to reduced TX power mid-shift on a new BP-279\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically around 3.7V per cell, not the full 4.2V per cell it holds after a complete charge. When the F1000 draws transmit current from a partially charged pack, voltage sags under RF load and the radio's protection circuit steps down TX power to stay within operating limits. This is not a faulty battery. Run a full charge cycle before the first shift and the radio will hold rated TX power through normal use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after installing the BP-279\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe F1000 uses voltage-threshold bar indicators — each bar corresponds to a voltage band across the 7.4V nominal range. A new pack at storage voltage reads low enough to land in the second or third bar bracket even though the cell is healthy. After a full charge cycle the resting voltage will sit above 8.0V and the indicator will show the top bar. If the indicator still reads low after a complete charge, check that the dock contacts are clean and that the charge LED confirmed a full cycle before pulling the pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426181218394,"sku":"BWCS-ICM880TC-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426181251162,"sku":"BWCS-ICM880TC-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426181283930,"sku":"BWCS-ICM880TC-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM880TC-1.webp?v=1779930436","url":"https:\/\/batteryweb.com\/products\/icom-f1000-replacement-battery-74v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
