It replaces the original battery when the cell can no longer hold a charge or degrades through repeated cycles. Capacity is 5.92Wh at a slim 4.74mm thick — matching the Q200's original battery footprint at 67.52 x 44.11mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQ200 platform fit:\u003c\/strong\u003e\n    The Q200 uses a sealed Li-Polymer pouch cell at 3.7V nominal. The connector pinout and physical dimensions are specific to this model — swapping in a mismatched cell risks a BMS rejection or a poor physical fit inside the chassis.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through charge and discharge cycles on the bench. The BMS accepted the charging handshake cleanly and the protection circuit tripped correctly at both the low-voltage and over-current thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging if the Q200 supports it and run one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before the OS starts reporting percentage from it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Q200 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Q200's fuel gauge IC uses a coulomb counter calibrated to the original cell's discharge curve. When a new cell goes in, that curve no longer matches the data the IC was tracking. The OS reads percentage from the IC, not directly from cell voltage, so the reported number drifts from actual charge state. One complete discharge to around 3.2V followed by a full charge brings the counter back into alignment with the new cell.\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 modem or screen pulls a current spike the cell cannot sustain without the voltage dropping below the BMS cutoff threshold. The OS shows 25% because the fuel gauge IC hasn't recalibrated yet — the actual usable charge ends sooner than the counter predicts. It's most visible when switching from Wi-Fi to mobile data or waking the screen from standby. Run one full calibration cycle first; if shutdowns persist after that, check that the cell connector is fully seated and making clean contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405206585434,"sku":"BWCS-MU6150SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405206618202,"sku":"BWCS-MU6150SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405206650970,"sku":"BWCS-MU6150SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MU6150SL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/anow-q200-replacement-battery-37v-1600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
