It replaces the original pack when capacity has degraded or the cell no longer holds a working charge. Voltage and form factor match the original battery bay on all four variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL10 platform compatibility:\u003c\/strong\u003e\n    The L10, L10i, L10ig, and L10ig LTE share the same battery bay geometry, contact layout, and 3.7V voltage rail. One battery fits all four — the BMS negotiation handshake runs the same across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge cycle and a PTT transmit load test. The BMS held steady under the transmit current spike and released cleanly when the load dropped — no false overcurrent trip.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the dock:\u003c\/strong\u003e\n    If the dock LED shows a fault on the first seating, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The L10 charger 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 L10 cuts out mid-transmission on a fresh battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew cells ship at storage voltage — typically around 3.6V — not a full charge. When you press PTT, the radio draws a sharp transmit current spike. If the cell voltage is low enough, the BMS reads that spike as an overcurrent event and trips the protection circuit. The radio cuts out, not because the battery is faulty, but because the cell needs a full charge cycle before it can handle peak TX load. Charge the pack completely before the first use in a high-draw transmit scenario.\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 L10 uses a voltage-threshold bar indicator — each bar corresponds to a voltage band, not a percentage read from a chip. A new battery at storage voltage sits at roughly 3.6V, which maps to a lower bar than a fully charged cell at 4.1–4.2V. This is not a fault with the replacement pack. Charge the battery fully in the dock and the bar indicator will rise to reflect the correct resting voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426303869018,"sku":"BWCS-MOX100TW-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426303901786,"sku":"BWCS-MOX100TW-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426303934554,"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\/lex-l10-replacement-battery-37v-4500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
