It restores power to the navigation unit when the original cell no longer holds a usable charge. Dimensions are 52.96 × 33.64 × 5.15mm — measure your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLeadtek 9559x fit:\u003c\/strong\u003e\n    The 9559x uses a single-cell 3.7V Li-ion pack with a low-current BMS matched to GPS receiver and display draw. This cell runs the same voltage rail and connector, so the unit powers on and charges without modification.\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 a GPS-class load. The BMS held cutoff at the correct low-voltage threshold and accepted a full charge without triggering protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold-start after battery swap:\u003c\/strong\u003e\n    After fitting this cell, power the GPS on outdoors and let it acquire a satellite fix before driving. The unit performs a cold start after any full power interruption — first fix takes 5–10 minutes versus under a minute on a warm start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy dropping at low battery on the 9559x\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS units reduce receiver sensitivity as cell voltage falls below roughly 3.5V to conserve power. On the 9559x, this shows up as position jumps or a weaker satellite count before the unit shuts off. It is not a signal or antenna fault — it is a deliberate power-saving response in the receiver firmware. Replacing the cell with a fresh 1000mAh unit restores full receiver sensitivity across the charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003e9559x shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter years of cycling, the original cell's capacity drops while the unit's voltage-threshold indicator stays calibrated to a new cell. The GPS reads the voltage as acceptable until it suddenly hits the hard cutoff, giving no visual warning before shutdown. The indicator effectively lies because it was never recalibrated to the degraded cell's discharge curve. Fitting a new 1000mAh cell resets the usable voltage window — the low-battery warning appears at the correct point in the discharge cycle again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377693294682,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377693327450,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377693360218,"sku":"BWCS-XEW01SL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XEW01SL-1.webp?v=1778771896","url":"https:\/\/batteryweb.com\/products\/leadtek-9559x-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
