It replaces OEM packs BP120, BP150, BP180, and BP250. The cells match the voltage rail and connector footprint the IC-T7 platform expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-T7A \/ IC-T7H \/ IC-T22A \/ IC-T42A platform fit:\u003c\/strong\u003e\n    These radios share the same 4.8V four-cell Ni-MH voltage rail and identical battery bay connector. One pack covers all listed models because the BMS handshake and contact pinout are common across the series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on an IC-T7A body. The BMS accepted charge normally from the dock, PTT transmit drew current without triggering overcurrent cutoff, and the radio held RX standby without voltage collapse.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the dock:\u003c\/strong\u003e\n    Ni-MH packs ship at partial storage charge — typically 3.8–4.2V. If the dock shows a fault LED on first seating, wipe the gold contact strip with a dry cloth, reseat the pack firmly, and wait 10 seconds. The Icom dock requires a clean contact cycle to recognise the BMS before it begins charging.\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-T7A cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eTransmit current on the IC-T7A spikes sharply the moment PTT is pressed — the RF output stage draws significantly more current than RX standby. A new Ni-MH pack at storage voltage has higher internal impedance, so that initial spike can cause a brief voltage sag. If the pack voltage dips below the radio's low-voltage cutoff threshold during that spike, the radio drops TX before the cell has warmed into normal operation. Running one to two full charge-discharge cycles lowers cell impedance and the cutout stops. If it persists past three cycles, check that the contact strip is clean and fully seated.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a fully charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-T7 series reads voltage thresholds directly — there is no fuel gauge chip. A new pack straight off the charger can sit at a resting voltage just under the threshold for the top bar, because the cell voltage settles slightly after charge termination. This is not a fault with the pack. Key the radio for a short transmission cycle, let it rest five minutes, then recheck — resting voltage will stabilise above the threshold. If the indicator stays low after two full charge cycles, measure open-circuit voltage at the contacts; a healthy fully charged 4.8V Ni-MH pack should read 5.4–5.6V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426372190298,"sku":"BWCS-SC150BL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426372223066,"sku":"BWCS-SC150BL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426372255834,"sku":"BWCS-SC150BL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SC150BL_1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/icom-ic-t7a-replacement-battery-48v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
