It replaces OEM part numbers BP-279, BP-280, and BP-280LI. Voltage and connector footprint match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF1000 series compatibility:\u003c\/strong\u003e\n    The F1000, F1000D, F1000S, and F1000T all share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. One pack covers the full family 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 charge, discharge, and PTT transmit cycles on the F1000 platform. The BMS held the voltage rail steady under transmit load and tripped cleanly at the low-voltage cutoff threshold — no erratic shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the Icom dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and firmly reseat it. The Icom charging platform requires a clean contact cycle to accept the new 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\"\u003eIC-F1000 radio cutting out the moment PTT is pressed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe F1000 draws a sharp current spike the instant the PTT button is pressed — transmit current climbs fast and briefly. If the battery's BMS reads that spike as an overcurrent event, it trips and cuts power before the radio even keys up. This happens more often with new packs still sitting at storage voltage rather than a full charge. A full charge cycle to 8.4V before first field use prevents the BMS from tripping on that initial transmit surge.\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 F1000 reads battery level using voltage-threshold detection, not a fuel gauge chip. A new cell delivered at storage voltage — typically around 7.4V — can sit one threshold band below a fully charged cell at 8.4V, making the display read one bar low. This is not a faulty cell. Put the pack through one complete charge cycle in the Icom dock and let it reach 8.4V before drawing any conclusions about capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426335686746,"sku":"BWCS-ICM880TW-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426335719514,"sku":"BWCS-ICM880TW-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426335752282,"sku":"BWCS-ICM880TW-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM880TW-1.webp?v=1779930721","url":"https:\/\/batteryweb.com\/products\/icom-f1000-replacement-battery-74v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
