It cross-references OEM part numbers including RNN4007AR, NTN8923AR, NTN8294AR, NNTN7453A, and NNTN4435B. Capacity is drawn from product data — 32.25Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXTS platform fit:\u003c\/strong\u003e\n    The XTS3000, XTS3500, and XTS5000 share the same battery bay geometry, contact array, and BMS handshake voltage thresholds. One pack covers all three bodies without adapter or modification. The Tetra MTP200 uses the same form factor under a different OEM numbering scheme.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and transmit-load discharge on an XTS3000 chassis. The BMS held stable under repeated PTT-triggered current spikes and did not trigger overcurrent cutoff at standard rated TX power.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion — contact cycle on XTS dock:\u003c\/strong\u003e\n    If the Motorola multi-unit charger shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The XTS charging platform requires a clean contact cycle before it accepts the new 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\"\u003eWhy the XTS3000 cuts out mid-transmission on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically around 3.7–3.8V per cell, not full charge. When the XTS3000 keys up to transmit, the RF amplifier draws a sharp current spike. If the pack is at storage voltage, that spike causes a brief voltage sag that can dip below the BMS overcurrent threshold. The radio interprets this as a fault and drops the transmission. A full charge cycle before field deployment eliminates this — the pack needs to be at or above 8.0V total before the first shift.\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 XTS series uses a voltage-threshold bar indicator — it reads pack voltage directly, not a fuel gauge chip. A new pack at storage voltage reads lower on that scale, so the radio displays one or two bars even though the cell is not depleted. This is not a fault with the battery or the radio. Charge the pack fully in the dock until the charger LED goes solid green, then reinsert — the indicator will show full bars at or above 8.2V resting voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426358296666,"sku":"BWCS-MTX350TW-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426358329434,"sku":"BWCS-MTX350TW-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426358362202,"sku":"BWCS-MTX350TW-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTX350TW-1.webp?v=1779930881","url":"https:\/\/batteryweb.com\/products\/motorola-xts3000-replacement-battery-75v-4300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
