It fits the IC-703 and IC-703 Plus portable HF transceivers. These radios draw sustained current during SSB transmission, so this pack matches the original voltage rail and connector exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-703 and IC-703 Plus compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay, connector pinout, and 9.6V supply requirement. The BMS handshake is identical across both variants, so one pack covers either unit without modification.\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-703 chassis. The BMS held voltage within spec across the Ni-MH cell array and did not trigger overcurrent cutoff during simulated PTT events at full RF output.\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 seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The IC-703 charging dock requires a clean contact cycle to complete the BMS handshake before 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-703 dropping to low TX power mid-QSO on a new BP-228 pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-703 monitors supply voltage and steps down RF output when the battery rail sags below threshold — typically around 8.5V under load. A new Ni-MH pack shipped at storage voltage sits near 9.0V open-circuit but can sag further during the first few transmit cycles before the cells stabilise. This is not a fault in the pack. Run two full charge-discharge cycles through the dock before field use and the voltage sag under PTT will reduce significantly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting a new BP-228\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-703 reads battery level from a simple voltage-threshold indicator — it has no fuel gauge chip. A new Ni-MH cell delivered at storage voltage reads lower than a fully charged pack, so the radio displays one or two bars immediately after fitting. This is not a capacity problem. Charge the pack fully through the Icom dock until the charge LED goes green, then power on — the indicator should read at or near full at 9.6V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426318319706,"sku":"BWCS-ICM703TW-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426318352474,"sku":"BWCS-ICM703TW-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426318385242,"sku":"BWCS-ICM703TW-3","price":105.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM703TW-1.webp?v=1779930633","url":"https:\/\/batteryweb.com\/products\/icom-ic-703-replacement-battery-96v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
