It uses the same contact pinout and BMS communication protocol as the original Motorola pack. Replacement OEM part numbers covered include NTN7034, NNTN7034A\/B, PMNN4487A, NNTN7038, NNTN8921 series, PMNN4486, NNTN7035, and PMMN4403.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAPX platform compatibility:\u003c\/strong\u003e\n    The APX6000 and APX7000 families share a common battery bay geometry, contact strip layout, and BMS handshake voltage. Both run a 7.4V nominal rail, so a single pack covers both series without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack in an APX7000 dock and confirmed the BMS completed the full charge handshake without fault LED. Under simulated PTT transmit loads, the voltage rail held stable and the radio maintained full TX power throughout the draw cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the dock shows a fault LED on first seating, remove the pack and wipe the gold contact strip with a dry cloth. Reseat firmly. The APX platform requires a clean contact surface to complete the initial BMS negotiation before charging starts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the APX7000 cuts out mid-transmission on a brand-new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically 3.6–3.7V per cell, not full charge. When the APX7000 transmits, it pulls a surge of current that the BMS may interpret as an overcurrent event if the cell voltage is already at the low end of the storage window. The BMS responds with a momentary cutoff, which kills the transmission. A full charge cycle before field use brings both cells to 4.2V each, giving the BMS enough headroom to absorb the TX current spike cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after installing a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe APX series uses voltage-threshold bar indicators, not a fuel-gauge chip. At storage voltage, the radio reads the pack as partially discharged and displays fewer bars accordingly. This is not a fault with the battery. Charge the pack fully in the dock until the charger LED goes solid green, then reinsert — the bar indicator will update to reflect the actual cell voltage of approximately 8.4V at full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426236137562,"sku":"BWCS-MPX700TC-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426236170330,"sku":"BWCS-MPX700TC-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426236203098,"sku":"BWCS-MPX700TC-3","price":100.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MPX700TC-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/motorola-apx7000-replacement-battery-74v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
