It replaces OEM part numbers PMNN4047, FTN6573, FTN6574, PMN4047BR, and PMR4047. If your original pack is no longer holding a charge between shifts, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMTP700 and MTP750 platform fit:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One pack covers both radios without any hardware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the MTP700 charge dock and confirmed BMS initialisation, full charge acceptance, and correct voltage output across the contact strip. The protection circuit responded correctly to charge termination at capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the dock:\u003c\/strong\u003e\n    If the charger shows a fault LED on first seat, pull the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The MTP platform requires a clean contact cycle before it accepts the BMS handshake and begins charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMTP700 cutting out or dropping TX power mid-transmission on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring PTT, the MTP700 draws a sharp current spike to drive the RF output stage. If the battery's BMS detects this spike as an overcurrent event, it interrupts the load for a fraction of a second — long enough to drop the transmission. A new pack at storage voltage (typically around 3.7–3.8V per cell) is more vulnerable to this trip point than a fully charged pack. Charge the battery to full before the first shift and the BMS trip threshold will sit well above the transmit current spike.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting this pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MTP700 reads battery level using voltage thresholds, not a chip that tracks charge history. A new Li-ion cell ships at storage voltage, not full charge, so the radio registers fewer bars even though the pack is not faulty. Place the pack in the charger dock for a full charge cycle. Once the cell voltage reaches its top-of-charge level near 8.4V across the pack, the indicator will read correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426355511386,"sku":"BWCS-MTP700TW-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426355544154,"sku":"BWCS-MTP700TW-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426355576922,"sku":"BWCS-MTP700TW-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTP700TW_1.webp?v=1779930881","url":"https:\/\/batteryweb.com\/products\/motorola-mtp700-replacement-battery-75v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
