These are field survey instruments used for real-time positioning, site layout, and data collection. The OEM part numbers 890-0163, 890-0163-XXQ, and KLN01117 all cross to this replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRanger 3 series compatibility:\u003c\/strong\u003e\n    The Ranger 3, 3XR, 3RC, and 3XC share the same 11.1V battery bay, connector pinout, and BMS communication protocol. One pack fits across the entire platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through GNSS acquisition, active data logging, and Bluetooth transmission simultaneously. The BMS held stable output across the combined draw and tripped correctly at the low-voltage cutoff threshold — no false shutdowns during sustained field-load simulation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install calibration step:\u003c\/strong\u003e\n    After fitting a new pack, run a full calibration cycle through the Ranger 3 instrument menu before field deployment. The Ranger 3 maps battery state during that process — skipping it causes premature low-battery warnings on the first measurement session even with a full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRanger 3 shutting down mid-survey despite showing charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ranger 3 draws a surge current when the GNSS engine locks onto a new constellation or when the radio modem transmits a correction signal. If the cell voltage sags below the BMS cutoff threshold during that spike — even briefly — the instrument shuts off. An aged original pack with elevated internal resistance fails this test even at 60–70% indicated charge. A fresh pack with lower internal resistance handles the transient without tripping. If this shutdown pattern repeats, check that the battery contacts are clean and seated fully before ruling out the pack itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRanger 3 not recognising a new battery after the unit sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs self-discharge during storage. If the cell voltage drops below approximately 2.5V per cell — around 7.5V total for an 11.1V 3S pack — the BMS enters a protection sleep state and the instrument will not power on or begin charging normally. Connect the battery to the Ranger 3 charger and leave it for 15–20 minutes without interruption; most chargers apply a low-current recovery pulse that wakes the BMS. If the charger LED does not respond after 20 minutes, try a different USB-C or dock port to confirm the charger is outputting voltage before assuming the pack is unrecoverable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360665174106,"sku":"BWCS-TRS300XL-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360665206874,"sku":"BWCS-TRS300XL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360665239642,"sku":"BWCS-TRS300XL-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRS300XL-1.webp?v=1778616178","url":"https:\/\/batteryweb.com\/products\/spectra-precision-ranger-3-replacement-battery-111v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
