It fits the P5100, P5130, P5150, and P5200, along with several additional models in the same family. The OEM part numbers it replaces include SPD2000, XPPA2H, BKB191210\/34, BT-01942-001, BT-01942-002, and MAHT-NPA2J.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP5100 family compatibility:\u003c\/strong\u003e\n    The P5100, P5130, P5150, and P5200 share the same battery bay format, connector pinout, and BMS handshake protocol. One pack serves the full platform 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 charge and discharge on a Harris P5100 body. The BMS handled PTT transmit current spikes cleanly and the charger dock accepted the pack without fault LED on the first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    Harris dock chargers use a contact-verification step before accepting a new pack. If the dock LED flashes a fault on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. This clears any oxide layer and lets the dock complete its recognition cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the P5100 cuts out mid-transmission on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT on the P5100 draws a sharp current spike as the RF output stage ramps up. If the cell voltage is at storage level — typically around 6.0V for a freshly shipped Ni-MH pack — the BMS can trip on that inrush and drop the radio before the transmission completes. The fix is a full conditioning charge before the first use shift. Once the pack reaches its rated 7.2V resting voltage, the transmit current spike stays within the BMS window and the cutout stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHarris P5100 radios use voltage-threshold bar indicators, not a fuel gauge chip. A new Ni-MH pack often needs one or two full charge-discharge cycles before the cells stabilise at peak capacity. If the indicator shows one bar low after the first charge, run the radio to the low-battery warning, then charge fully again. After two cycles the resting voltage typically holds above 7.0V and the bar display reflects the correct state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426345517146,"sku":"BWCS-MCR700TW-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426345549914,"sku":"BWCS-MCR700TW-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426345582682,"sku":"BWCS-MCR700TW-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCR700TW_1.webp?v=1779930783","url":"https:\/\/batteryweb.com\/products\/harris-p5100-replacement-battery-72v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
