It fits the LEX L10, L10i, L10ig, and L10ig LTE variants. The OEM part numbers covered are PMNN4475, PMNN4475B, and PA33GAB013A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLEX L10 series compatibility:\u003c\/strong\u003e\n    The L10, L10i, L10ig, and L10ig LTE all share the same battery bay geometry, contact layout, and BMS handshake protocol. One pack covers the full platform without any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on an L10ig LTE. The BMS responded correctly to transmit-current spikes at PTT press, and protection thresholds triggered at expected voltage floors — no false lockouts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on a dock:\u003c\/strong\u003e\n    If the charger dock shows a fault LED when you seat this pack for the first time, pull the battery out, wipe the gold contact strip with a dry cloth, and reseat firmly. The LEX L10 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 LEX L10 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell ships at storage voltage — typically around 3.6–3.8V — not at full charge. When you key the PTT on an uncharged pack, the transmit-current draw spikes sharply, and the BMS can interpret this as an overcurrent event. The radio drops the transmission to protect the cell. Charge the pack fully before the first field use and the BMS will operate against a full voltage headroom, eliminating false cutoffs under TX load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LEX L10 uses a voltage-threshold bar indicator — each bar corresponds to a voltage band. A freshly inserted pack at storage voltage sits in a lower band and displays one or two bars even though the cell is healthy. This is not a capacity defect. Put the pack on the dock, charge to full, and the indicator will step up to the correct bar count once resting voltage stabilises above the top threshold — typically 4.1V or higher on a 3.7V nominal cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426304000090,"sku":"BWCS-MOX100TW-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426304032858,"sku":"BWCS-MOX100TW-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426304065626,"sku":"BWCS-MOX100TW-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MOX100TW-1.webp?v=1779930602","url":"https:\/\/batteryweb.com\/products\/motorola-lex-l10-replacement-battery-37v-4500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
