It fits the same battery bay, connector, and BMS interface across all four models. Capacity is rated at 3.7Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG-Trender \/ WBT series compatibility:\u003c\/strong\u003e\n    All four models share the same 3.7V single-cell architecture, connector pinout, and BMS communication protocol. The battery bay dimensions — 52.96 × 33.64 × 5.15mm — are identical across the range, so one cell fits all 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 the WBT platform and monitored BMS cutoff behaviour. The protection circuit tripped correctly at low-voltage threshold and accepted a full charge cycle without fault flags.\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 acquire a satellite fix before heading out. GPS navigation devices run a cold start after any full power interruption — first fix typically takes 5–10 minutes. Subsequent warm starts drop back under a minute once almanac data is restored.\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 G-Trender\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt low state of charge, some GPS receivers step down receiver sensitivity to reduce current draw and extend operation. On the G-Trender this can appear as wider position scatter or slower track updates before the unit shuts off. It is not a firmware fault — it is the receiver managing power at the cell's lower voltage boundary. Keeping the cell above 3.6V under load maintains full receiver sensitivity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eG-Trender shuts off without warning before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge on the G-Trender reads state of charge from a voltage curve calibrated to the original cell. A new or different cell may have a slightly different discharge curve, so the indicator can read one bar and still cut off abruptly. This is a calibration lag in the gauge, not a fault with the cell. Run two or three full charge-discharge cycles and the indicator will recalibrate — cutoff should align closer to the 3.4V low-voltage threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377697423450,"sku":"BWCS-XEW01SL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377697456218,"sku":"BWCS-XEW01SL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377697488986,"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\/wintec-g-trender-replacement-battery-37v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
