It replaces OEM part numbers BPRP1100, BPRP1500, and BPRP1500MH. Capacity is 2000mAh (14.4Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRPU\/RPV platform compatibility:\u003c\/strong\u003e\n    The RPU416, RPU599, RPV516, and RPV516A share the same 7.2V battery bay, connector pinout, and BMS handshake protocol. One pack fits the full group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on RPV516 hardware. The BMS accepted the charger handshake on first insertion and held steady voltage under simulated PTT transmit load without triggering overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact check:\u003c\/strong\u003e\n    Bendix-King charger docks on this platform require a clean contact cycle to register a new pack. If the dock shows a fault LED on first seating, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly before attempting to charge again.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RPU416 cuts out mid-transmission on a freshly inserted battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT on the RPU416 draws a sharp current spike — sometimes 2–3x the standby draw — as the radio hits full RF output. A Ni-MH cell that shipped at storage voltage, typically around 6.0–6.4V on a 7.2V pack, can sag below the BMS undervoltage threshold during that spike and trip a momentary cutout. This is not a faulty battery. Run the pack through one full charge cycle before putting the radio back on shift and the cell voltage will be at nominal, where it handles transmit peaks cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RPU416 and RPV516 use a simple voltage-threshold bar indicator — each bar lights above a fixed voltage step. A new Ni-MH cell at storage voltage reads lower than a fully charged one, so the radio may show two bars on a pack that still has significant capacity remaining. This is a voltage reading, not a capacity fault. Charge the pack fully — the indicator should read at the top bar once the pack reaches 8.4–8.6V off the charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426356658266,"sku":"BWCS-KNB140TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426356691034,"sku":"BWCS-KNB140TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426356723802,"sku":"BWCS-KNB140TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KNB140TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/bendix-king-rpu416-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
