It replaces the original battery when the cell has degraded past the point of holding a usable charge through a normal day. Dimensions are 53.00 × 33.90 × 5.70mm — verify your existing cell matches before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX7-Scan platform fit:\u003c\/strong\u003e\n    The X7-Scan runs a single-cell 3.7V nominal rail with a fixed connector layout. This cell matches that voltage rail and physical footprint. No modification to the connector or housing is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the X7-Scan platform. The BMS accepted the cell without fault codes, and charge termination triggered correctly at 4.2V. Capacity measured at rated spec across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This gives the fuel gauge IC time to recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell. Skip this step and the percentage readout will drift.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the X7-Scan reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe X7-Scan uses a fuel gauge IC that tracks capacity by comparing real-time voltage and current draw against a stored discharge curve — one that was calibrated to the original cell. When you install a new cell, that stored curve no longer matches the new cell's actual voltage-versus-capacity profile. The result is a percentage readout that jumps, stalls, or reads high until the phone drains to near-zero. One full discharge to automatic shutdown followed by a full uninterrupted charge resets the coulomb counter against the new cell and restores accurate reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell hits a voltage cliff under load — the modem, screen, or a background process pulls current the cell cannot sustain, and voltage drops below the BMS cutoff threshold even though the fuel gauge still shows charge remaining. It is more common in the first few cycles on a new cell before the gauge IC has calibrated. Run two or three full discharge-charge cycles without interruption. If shutdowns continue past that point, check that the cell is seated flush and the connector contacts are clean, then confirm resting voltage reads at least 3.7V with a multimeter before the next boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405033144410,"sku":"BWCS-NK5CHL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405033177178,"sku":"BWCS-NK5CHL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405033209946,"sku":"BWCS-NK5CHL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK5CHL-1.webp?v=1779369842","url":"https:\/\/batteryweb.com\/products\/reflecta-x7-scan-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
