It fits directly into these portable navigation and magnification devices. Capacity figure is 1700mAh (6.29Wh) — sourced from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSnow and Snow 4.3\" platform fit:\u003c\/strong\u003e\n    Both Snow variants share the same battery bay dimensions and the same BMS voltage thresholds. The 66.20 × 44.00 × 5.10mm cell geometry and OEM part number R001710000 confirm the match — no connector modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Snow platform and monitored BMS cutoff behaviour. The protection circuit held charge termination at the correct 4.2V ceiling and low-voltage cutoff triggered cleanly before cell damage thresholds were reached.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start satellite acquisition after swap:\u003c\/strong\u003e\n    After fitting this cell, power the unit on outdoors and let it run through a full cold-start GPS acquisition before relying on it for navigation. A cold start after full power removal takes 5–10 minutes for the first satellite fix — this is normal GPS behaviour, not a fault with the battery.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy reduced at low battery on the Snow\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zoomax Snow's GPS receiver draws consistent power to maintain satellite lock and signal processing. When cell voltage drops toward the lower threshold, the device firmware on some GPS units scales back receiver sensitivity to stretch remaining charge. This can show up as position drift or longer re-acquisition times even before the battery indicator reads empty. Keeping the cell above 3.6V during active navigation avoids this sensitivity reduction entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off without warning before the battery indicator empties\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a new cell's capacity curve hasn't been learned by the device's fuel gauge or when the original cell was so degraded that the gauge calibration drifted. The Snow reads voltage to estimate remaining charge — a fresh 1700mAh cell discharges differently than a worn one, so the indicator can show one bar and immediately trip the BMS cutoff. Run two full charge-to-cutoff cycles after fitting this replacement to let the device recalibrate its shutdown threshold against the new cell's actual voltage curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377636245594,"sku":"BWCS-SDV350SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377636278362,"sku":"BWCS-SDV350SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377636311130,"sku":"BWCS-SDV350SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDV350SL-1.webp?v=1778611066","url":"https:\/\/batteryweb.com\/products\/zoomax-snow-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
