It replaces a swollen, dead, or heavily degraded original cell. Dimensions are 25.00 × 24.80 × 5.40mm — measure your existing cell before ordering if you are unsure.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGTR 2E \/ A2023 fitment:\u003c\/strong\u003e\n    Both model references share the same PCB layout, connector pitch, and fuel gauge IC, so one cell covers both. No adapter or wiring modification needed — the connector seats directly on the board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the GTR 2E's BMS at full charge and confirmed the fuel gauge IC accepted the new cell without throwing a low-voltage lockout. Charge termination triggered cleanly at 4.35V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap charging protocol:\u003c\/strong\u003e\n    After fitting this cell, place the watch on its magnetic charger immediately and run it to 100% before wearing it. The GTR 2E fuel gauge IC loses its reference point when the cell is swapped and cannot recalibrate without one complete charge cycle from near-zero.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GTR 2E reports 0% and shuts off right after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GTR 2E uses a coulomb-counting fuel gauge IC that tracks charge state relative to a stored baseline. When you disconnect the old cell, that baseline is wiped. The IC wakes up with no reference and defaults to 0%, triggering an immediate low-battery shutdown. This is not a fault with the replacement cell. Placing the watch on the charger and allowing a full charge to 100% writes a new baseline to the IC and resolves the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery draining in one day instead of the expected multi-day cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the GTR 2E, always-on display mode combined with continuous heart rate monitoring can pull significantly more current than the watch's default power profile. Check Settings → Display and confirm always-on is off, and set heart rate monitoring to Smart or 30-minute intervals rather than continuous. GPS logging during outdoor workouts adds further draw — this is normal behaviour, not a cell defect. If drain continues after adjusting these settings, let the watch complete two full charge cycles before drawing conclusions on capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416159584346,"sku":"BWCS-AMR202SH-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416159617114,"sku":"BWCS-AMR202SH-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416159649882,"sku":"BWCS-AMR202SH-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMR202SH-1.webp?v=1779760504","url":"https:\/\/batteryweb.com\/products\/amazfit-gtr-2e-replacement-battery-385v-460mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
