It slots directly into the battery compartment on the back of the radio and connects via the same multi-pin contact strip as the original Icom pack. Capacity is 1950mAh \/ 14.43Wh — pulled from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-92 series fit:\u003c\/strong\u003e\n    The IC-92, IC-92AD, and IC-E92D share the same battery bay geometry and BMS handshake protocol. All three expect a 7.4V two-cell Li-ion pack with the BP-256 contact layout — swapping between any of these models carries no compatibility risk.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles on an IC-92AD dock. The BMS accepted the initial handshake without fault, voltage rose steadily through CC and CV phases, and the charger stepped down cleanly to trickle at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact check:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the battery and wipe the gold contact strip with a dry cloth before reseating. The IC-92 platform requires a clean contact cycle before the BMS handshake is accepted and 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-92 transmit current spike and BMS overcurrent response\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you press PTT on the IC-92, transmit current jumps sharply — far above receive or standby draw. A new BP-256 pack at storage voltage sits around 3.7V per cell, which is lower than a fully charged cell at 4.2V. At storage voltage, internal resistance is slightly higher, so the current spike on PTT is closer to the BMS overcurrent threshold. A full charge cycle before heavy PTT use brings cell voltage up and reduces the risk of a BMS trip during transmission.\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-92 reads battery level from cell voltage at the contact pins — it does not track charge history. A new BP-256 shipped at storage voltage will read one or two bars short of full, even though the cell capacity is intact. This is not a faulty pack. Put it on the dock, run a complete charge cycle until the charger LED goes green, then reinsert — the indicator will read correctly at the full-charge resting voltage of approximately 8.2V across both cells.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426276507738,"sku":"BWCS-ICM256TW-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426276540506,"sku":"BWCS-ICM256TW-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426276573274,"sku":"BWCS-ICM256TW-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM256TW-1.webp?v=1779930584","url":"https:\/\/batteryweb.com\/products\/icom-ic-92-replacement-battery-74v-1950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
