It replaces OEM part numbers BPRP1100, BPRP1500, and BPRP1500MH. Voltage and form factor match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRPU\/RPV platform fit:\u003c\/strong\u003e\n    The RPU416, RPU499, RPU516, and RPV416 share the same battery bay dimensions, 7.2V voltage rail, and contact layout. One pack covers this 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 full charge and load cycles on the RPU platform. The BMS accepted the charge sequence normally and held voltage across both standby and transmit load draws without tripping cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip condition on first insertion:\u003c\/strong\u003e\n    If the charger dock shows a fault or blink on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The RPU charger dock requires a clean contact cycle to complete the BMS handshake 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\"\u003eRPU416 bar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells ship at storage voltage, typically 1.1–1.2V per cell, not full charge. The RPU416 reads pack voltage against fixed thresholds to light its bar segments, so a new pack at storage voltage will display one or two fewer bars than a fully charged one. This is not a cell fault. Run a full charge cycle first — the dock will show solid charge LED — then check the indicator again at resting voltage above 8.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cuts out mid-transmission on the RPU416 with a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT on these radios draws a sharp current spike — transmit current can jump 3–5× standby draw in under a millisecond. If the replacement pack's cells haven't completed at least one full charge-discharge cycle, internal impedance is higher than normal and voltage briefly sags under that spike. The BMS reads the sag as an unsafe drop and trips cutoff, killing the transmission. Charge the pack fully, use it until the indicator drops to one bar, then recharge — cell impedance drops significantly after the first full cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426356035674,"sku":"BWCS-KNB140TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426356068442,"sku":"BWCS-KNB140TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426356101210,"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\/regency-relm-rpu416-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
