It replaces OEM part numbers MA181 and BP4. These radios are used in aviation, marine, and emergency services — situations where a dead pack is not an option.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHH2500 \/ HH400 \/ MINIcom platform fit:\u003c\/strong\u003e\n    These models share the same 10.8V three-cell Ni-MH voltage rail, battery housing geometry, and contact layout. One replacement SKU covers the full group because the electrical and mechanical interface is identical across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on an HH2500 and cycled it through full charge and PTT load events. The BMS handled transmit current spikes without tripping, and cell voltage held stable across repeated keying cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle contact check on Bendix King docks:\u003c\/strong\u003e\n    If the charger shows a fault LED on first insertion, remove the pack, wipe the contact strip with a dry cloth, and firmly reseat it. The dock needs a clean contact to complete the BMS handshake before it will begin 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 HH2500 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at partial storage voltage — typically 1.0–1.1V per cell — not at full charge. On a fresh pack, the transmit current spike when PTT is pressed can cause the BMS to detect an undervoltage condition and momentarily cut power to the RF stage. This is not a defective pack. Run one full charge cycle before field use and the cutout behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HH2500 reads battery level from cell voltage thresholds, not a fuel gauge chip. A new Ni-MH pack at storage voltage sits below the top threshold, so the radio displays one bar short immediately after insertion. This corrects itself after the first complete charge cycle brings all three cells to 1.4V or above. No fault — charge the pack fully before reading the indicator.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426321891418,"sku":"BWCS-UPX500TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426321924186,"sku":"BWCS-UPX500TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426321956954,"sku":"BWCS-UPX500TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPX500TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/bendix-king-hh2500-replacement-battery-108v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
