The PhotoTrackr records GPS coordinates and timestamps during outdoor activities, syncing location data with photos for automatic geotagging. Original cells lose capacity after repeated charge cycles — this replacement restores full field operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePhotoTrackr platform fit:\u003c\/strong\u003e\n    The PhotoTrackr uses a compact single-cell Li-ion pack running at 3.7V nominal. This cell matches the original voltage rail and physical dimensions (52.96 × 33.64 × 5.15mm), so the BMS on the logger reads charge state correctly from first boot.\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 logger platform. The BMS accepted the cell without fault flags and regulated cutoff voltage behaved within expected Li-ion thresholds throughout testing.\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 PhotoTrackr on outdoors before your first session. GPS loggers perform a full cold start after any complete power interruption — first satellite fix can take 5–10 minutes. Subsequent warm starts drop that to under a minute once almanac data is cached.\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 PhotoTrackr\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome GPS receivers step down radio sensitivity when cell voltage drops toward the low-battery threshold. On the PhotoTrackr, this can show as increased position scatter or coordinate jumps during a logging session. The receiver draws more current during active satellite tracking than during standby, accelerating the voltage drop. Keep the cell above 3.5V during active use to maintain full receiver sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhotoTrackr shuts off without low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a full battery swap, the PhotoTrackr's fuel gauge is uncalibrated — it has no record of the new cell's actual capacity curve. The device hits its hardware voltage cutoff before the on-screen indicator reaches the last bar. Run two full charge-discharge cycles in the field to let the logger recalibrate its shutdown threshold. After calibration, the warning indicator will trigger reliably above the hard cutoff at approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377690706010,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377690738778,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377690771546,"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\/gisteq-phototrackr-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
