It fits the same physical housing and connector as the OEM pack, with a BMS matched to the voltage thresholds these radios use to drive their bar indicators. Capacity is sourced from the product data: 2200mAh \/ 16.28Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-F70 and IC-F80 platform fit:\u003c\/strong\u003e\n    Both models share the same 7.4V nominal rail, identical multi-pin connector, and the same BMS handshake protocol — which is why a single pack covers the full F70\/F80 line, including the D and DS variants. Swapping between those models does not require a different pack.\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 load on the IC-F70 chassis. The BMS held stable under PTT bursts and released cleanly after each transmit cycle without triggering overcurrent lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock LED shows a fault on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom dock requires a clean contact cycle to complete the BMS handshake before it will begin charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIC-F70 charger dock fault LED after BP-236 swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new BP-236 replacement shipped at storage voltage — typically around 3.7V per cell, or roughly 7.4V combined. Some Icom docks reject packs below their acceptance threshold and flash a fault LED instead of starting the charge cycle. This is a dock-side voltage check, not a faulty pack. To recover, hold the pack contacts against the dock terminals manually for 10–15 seconds, or try a different Icom-compatible charger that accepts packs from a lower starting voltage — once the pack reaches approximately 7.6V, the primary dock will accept it normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-F70 uses a simple voltage-threshold bar indicator — each bar maps to a voltage band, not a percentage from a fuel gauge chip. A pack fresh from storage sits at a lower resting voltage than a freshly charged OEM pack, so the radio displays one fewer bar even though the cells are healthy. Run a full charge cycle first. After charge completes and the pack rests for 10 minutes, resting voltage should sit at or above 8.2V — at that point the indicator will reflect actual capacity correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426322776154,"sku":"BWCS-ICM802TW-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426322808922,"sku":"BWCS-ICM802TW-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426322841690,"sku":"BWCS-ICM802TW-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM802TW-1.webp?v=1779930634","url":"https:\/\/batteryweb.com\/products\/icom-ic-f70-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
