It fits the IC-A6, IC-A6E, IC-A24, IC-A24E, and over 31 additional Icom models that share the BP-209, BP-210, BP-222, BP-209N, BP-210N, and BP-222N footprint. Capacity is 2200mAh (16.28Wh) — sourced from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-A6 and IC-A24 platform compatibility:\u003c\/strong\u003e\n    These models share the same battery bay geometry, 7.4V voltage rail, and BMS handshake protocol. A single cell pack covers the full lineup because Icom standardised the connector and BMS communication across this aviation transceiver generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the IC-A6 platform. The BMS engaged cleanly at full transmit current draw, and the voltage held steady through repeated PTT keying without tripping overcurrent protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom charger dock requires a clean contact cycle to accept the new BMS handshake before charging begins — this is not a faulty cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIC-A6 transmit current spike and BMS overcurrent cutoff\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you press PTT on an aviation transceiver, the transmit current draw jumps sharply — significantly higher than receive mode draw. A new replacement pack with a conservatively tuned BMS can interpret this spike as an overcurrent event and cut output for a fraction of a second. This is not a capacity problem; it is a BMS threshold calibration on first use. Running two or three full transmit cycles allows the BMS to log the radio's actual current signature and stop tripping on normal PTT events.\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\"\u003eNew lithium-ion cells ship at storage voltage — typically around 3.7V per cell, not the 4.2V peak of a full charge. The IC-A6 bar indicator reads voltage thresholds directly; it does not track charge history. A pack sitting at storage voltage will show one or two bars even though the cell is healthy. Charge the pack fully in the dock before drawing any conclusion — once it reaches 8.4V across both cells, the bar indicator will read correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426234237018,"sku":"BWCS-ICM210TC-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426234269786,"sku":"BWCS-ICM210TC-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426234302554,"sku":"BWCS-ICM210TC-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM210TC-1.webp?v=1779930493","url":"https:\/\/batteryweb.com\/products\/icom-ic-a6-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
