It replaces OEM part numbers RBP-22 and RBP-22H. Capacity is 13.2Wh — matched to the original spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePR-52 \/ PR-222 \/ PR-460 \/ PR-45 platform fit:\u003c\/strong\u003e\n    These four models share the same 12V battery bay, connector pinout, and BMS handshake protocol. A single pack covers all four units without modification or adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on a PR-52 body. The BMS handled the PTT current spike without tripping, and the protection circuit held stable across repeated keying bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the dock:\u003c\/strong\u003e\n    If the charger shows a fault LED when you seat a new pack, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The Pryme dock requires a clean contact cycle to accept 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\"\u003ePR-52 cutting out at the end of a long PTT press\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a steeper voltage drop under sustained transmit current than lithium chemistry. When you hold PTT for several seconds, the cell voltage sags. If it dips below the radio's low-voltage cutoff threshold, the PR-52 drops the transmission and may show a low-battery indicator even with capacity remaining. This is a voltage sag event, not a dead pack. Short, standard PTT bursts keep the draw within the cell's delivery curve and prevent the cutoff from triggering.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected straight out of the box\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells ship at storage voltage — typically around 1.2V per cell — not at full charge. The PR-52 reads voltage thresholds to set the bar display, so a new pack at storage voltage will show one or two bars short of full. This is not a fault. Run one full charge cycle on the dock until the LED goes green, then reseat the pack. The indicator will reflect the actual charged voltage, which should read at or near 12V under no load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426319007834,"sku":"BWCS-SHC130TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426319040602,"sku":"BWCS-SHC130TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426319073370,"sku":"BWCS-SHC130TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHC130TW-1.webp?v=1779930680","url":"https:\/\/batteryweb.com\/products\/pryme-pr-52-replacement-battery-12v-1100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
