It fits the XT2333, XT2333-2, XT2333-3, and XT2333-4 variants. The pack slots into the same footprint as the original at 89.30 × 64.00 × 4.70mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT2333 variant compatibility:\u003c\/strong\u003e\n    The XT2333-2, -3, and -4 share the same battery bay dimensions, connector pinout, and BMS handshake protocol as the base XT2333. Motorola kept the power architecture consistent across this sub-family, so one cell covers all variants 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 XT2333 platform. The BMS accepted the pack without triggering a charge fault, and the fuel gauge IC completed initial calibration across a full discharge cycle without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge calibration:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle on standard charging. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\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 XT2333 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new lithium-polymer cell has a different internal impedance profile than the aged cell the phone's fuel gauge IC trained on. When the modem fires a high-current burst or the screen peaks at full brightness, the new cell's voltage drops sharply under load — crossing the hardware cutoff threshold even while the OS still reads 25%. The fuel gauge hasn't recalibrated yet, so the percentage shown is wrong. One full discharge-charge cycle on standard charging corrects the curve and eliminates the false cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XT2333's charge controller negotiates fast charge only after it confirms the pack voltage and temperature are within a learned window. On a freshly installed cell, the controller defaults to standard 5V charging for the first cycle as a precaution — this is expected behaviour, not a fault. Once the fuel gauge IC completes one full calibration cycle, the fast charge handshake re-enables automatically. If fast charging still doesn't engage after a full cycle, confirm the charger outputs at least 9V\/2A and the USB-C cable is rated for fast charge current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391788777562,"sku":"BWCS-MXT233SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391788810330,"sku":"BWCS-MXT233SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391788843098,"sku":"BWCS-MXT233SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT233SL-1.webp?v=1779142036","url":"https:\/\/batteryweb.com\/products\/motorola-xt2333-replacement-battery-387v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
