These are professional-grade two-way radios used across public safety, emergency response, and enterprise communications. The pack delivers 24.79Wh of capacity in the same form factor as the original Motorola battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXTS\/MT\/PR platform fit:\u003c\/strong\u003e\n    The XTS1500, XTS2500, PR1500, and MT1500 share the same battery bay dimensions, contact pin layout, and 7.4V nominal voltage rail. That is why a single pack covers this group — the BMS handshake protocol and connector are identical across the platform.\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 XTS1500 body. The BMS held cutoff at the correct low-voltage threshold and did not trip on PTT press — including repeated back-to-back transmissions at full RF output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger 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 Motorola XTS platform requires a clean contact cycle to accept the new BMS handshake before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the XTS1500 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically 3.6–3.75V per cell, not the 4.2V full-charge ceiling. Under a PTT transmit spike, the XTS1500 draws a sharp current burst for RF output. If the pack has not been fully charged first, that spike can pull cell voltage below the BMS overcurrent threshold momentarily, triggering a cutoff that kills the transmission. The radio then resets and returns to standby as if nothing happened. A full charge cycle before first use resolves this — the cells need to reach full voltage before sustaining transmit-load current without sag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XTS series uses simple voltage-threshold bar indicators — each bar corresponds to a voltage band, not a fuel gauge IC reading. A new pack at storage voltage will read one or two bars low immediately after insertion. This is not a capacity defect. Place the battery in the charger and let it complete a full charge cycle. Once cell voltage reaches approximately 8.4V (4.2V per cell), the indicator will display the correct number of bars.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426233778266,"sku":"BWCS-MTX150TC-1","price":441.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426233811034,"sku":"BWCS-MTX150TC-2","price":527.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426233843802,"sku":"BWCS-MTX150TC-3","price":592.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTX150TC-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/motorola-xts1500-replacement-battery-74v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
