It fits Coolpad handsets that shipped with that original cell. Install it when the factory battery no longer holds charge or fails to power the device.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPLD-94 cell platform:\u003c\/strong\u003e\n    Coolpad phones running the CPLD-94 share a matched voltage rail, connector pinout, and BMS handshake profile. Swapping to this cell keeps the charge IC operating within its expected parameters — no voltage mismatch, no charge protocol rejection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on compatible Coolpad hardware. The BMS accepted the cell without error flags, and the charge IC completed a full cycle without thermal cutoff or charge-halt events.\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 and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes load 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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still referencing the old cell's discharge curve. The new cell hits a voltage cliff under modem or screen load before the OS expects it. The phone cuts out even though the reported percentage looks safe. Run one full discharge to near-zero and a complete charge cycle — this forces the coulomb counter to reset its state-of-charge baseline against the actual cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calibrates to the cell it was paired with at the factory. After a cell swap, its internal model no longer matches the new cell's actual capacity curve. You'll see percentages that jump, stall, or read high when the phone is close to empty. A single full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and restores accurate reporting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404314247258,"sku":"BWCS-DVG250SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404314280026,"sku":"BWCS-DVG250SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404314312794,"sku":"BWCS-DVG250SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DVG250SL-1.webp?v=1779369679","url":"https:\/\/batteryweb.com\/products\/coolpad-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
