It is a direct voltage and form-factor match for the XPR series battery bay. Capacity figures come from the product data, not third-party estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXPR and XPR3000 series compatibility:\u003c\/strong\u003e\n    The XPR7350, XPR3000, XPR3300, and XPR3500 all share the same 7.4V two-cell Li-ion architecture, battery bay dimensions, and connector pinout. One pack covers the full MOTOTRBO portable tier without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge, transmit-load cycling, and BMS handshake verification on an XPR7350 dock. The BMS accepted the charging cycle cleanly, and overcurrent protection tripped correctly under a simulated high-draw PTT event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on a Motorola IMPRES or standard dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The MOTOTRBO platform requires a clean contact cycle to complete the BMS handshake before charging begins — a single reseating clears this in most cases.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the XPR7350 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePTT current draw on the XPR7350 spikes sharply the moment the transmitter fires — this is a normal characteristic of the RF output stage. If the replacement pack's BMS is configured with a tight overcurrent threshold, that spike can trip the protection circuit and kill the transmission mid-key. The radio resets quickly, but the user experiences it as a dropout. This is not a cell defect; it is a BMS calibration issue at the boundary of the transmit current envelope. If dropouts persist after a full charge cycle, verify the dock completed a proper charge termination before field use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a new PMNN4409\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically around 3.7–3.8V per cell — not at full charge. The XPR series uses a voltage-threshold bar indicator, so a pack at storage voltage will display one or two bars even though the cells are healthy. This is not a capacity fault. Place the battery in a compatible dock and allow a full charge cycle to complete before reading the indicator. After a full charge, the bar indicator should reflect the 7.4V nominal pack voltage correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426329952346,"sku":"BWCS-MTK261TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426329985114,"sku":"BWCS-MTK261TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426330017882,"sku":"BWCS-MTK261TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTK261TW-1.webp?v=1779930784","url":"https:\/\/batteryweb.com\/products\/motorola-xpr7350-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
