It fits the XT1962-1, XT1962-4, XT1962-5, and related XT1962 variants. Capacity is 11.17Wh, matching the original JG30 specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT1962 variant coverage:\u003c\/strong\u003e\n    The XT1962 lineup shares a common battery bay, connector pinout, and BMS handshake across regional variants. One cell fits all listed models without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge cycle on an XT1962-4. The charge IC accepted the BMS handshake without errors, and current delivery stepped down correctly at the top-of-charge threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Moto G7 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Moto G7's fuel gauge IC retains the discharge curve of the old, degraded cell after a swap. When the new cell hits a voltage point the IC associates with near-empty on the old curve, it triggers an emergency shutdown — even though the cell still has usable charge. The fix is one full discharge-to-shutdown followed by an uninterrupted charge to 100%. After that cycle, the coulomb counter resets against the new cell's actual curve and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not recognised on first cycle after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after a cell swap, the Moto G7 may fall back to standard 5V charging instead of engaging fast charge. The charge IC performs a BMS negotiation at power-on — if the new cell's state-of-charge registers outside the expected window, the IC defaults to a conservative charge profile. Complete one full standard-rate charge cycle first. Fast charge will re-engage on subsequent cycles once the IC confirms cell health from the initial charge data.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391996067930,"sku":"BWCS-MXT962SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391996100698,"sku":"BWCS-MXT962SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391996133466,"sku":"BWCS-MXT962SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT962SL-1.webp?v=1779142856","url":"https:\/\/batteryweb.com\/products\/motorola-moto-g7-replacement-battery-385v-2900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
