It fits the IC-T7, IC-T7A, IC-T7H, and IC-T70, plus 18 additional compatible models. Voltage and connector match the OEM spec — no modification needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-T7 series pack compatibility:\u003c\/strong\u003e\n    The IC-T7, IC-T7A, IC-T7H, and IC-T70 all share the same battery bay geometry, contact layout, and 7.2V supply rail. One pack covers the full line because Icom carried the same BMS handshake protocol across every variant in this series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the IC-T7 platform and confirmed the BMS negotiated correctly with the radio's charge circuit on first insertion. Transmit current spikes during PTT did not trigger overcurrent cutoff at rated load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH packs:\u003c\/strong\u003e\n    Ni-MH cells ship at partial charge and reach full rated capacity after two to three full charge-discharge cycles in the radio — do not judge capacity from the first cycle. Run the radio on receive until the bar indicator drops, then charge fully before drawing any conclusions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the IC-T7 cuts out mid-transmission on a freshly inserted pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-T7 draws a sharp current spike the moment PTT is pressed — transmit current can briefly exceed 1A at full RF output. A new Ni-MH pack shipped at storage voltage (typically 6.8–7.0V) has not yet been conditioned, so internal cell resistance is higher than normal. Under that initial spike, voltage sag can trip the radio's low-voltage cutoff before the pack has warmed up. One full charge-discharge cycle lowers cell impedance and the cutout stops occurring.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger dock fault LED that never clears after BP-173 swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIcom's desktop charger checks contact resistance before accepting a pack — oxidation or contamination on the gold strip contacts causes the dock to reject the handshake and hold a fault LED. Remove the pack, wipe the gold contact strip firmly with a dry cloth, and reseat it with a positive click. If the fault LED still does not clear, check that resting voltage is above 6.0V with a multimeter — packs below that threshold need a slow pre-charge cycle before the dock will accept them.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426334638170,"sku":"BWCS-ICM220TW-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426334670938,"sku":"BWCS-ICM220TW-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426334703706,"sku":"BWCS-ICM220TW-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM220TW-1.webp?v=1779930721","url":"https:\/\/batteryweb.com\/products\/icom-ic-t7-replacement-battery-72v-1100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
