It uses OEM part number CPLD-110 and slots into the same battery bay as the original cell. If your phone won't hold a charge or shuts down unexpectedly, this cell replaces the degraded original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCoolpad 8076D, 5217, 8076, and 7060 compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, 3.7V nominal voltage rail, and CPLD-110 connector pinout. The BMS handshake is identical across the group, so one cell fits all four 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 8076D platform. The BMS accepted the cell without triggering protection cutoff, and the charge IC completed a full charge cycle to 4.2V without thermal intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge tip:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against 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 Coolpad 8076D after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue. The fuel gauge IC on the 8076D was calibrated to the discharge curve of the original, worn cell. When the phone reads 20–30% on the new cell, the voltage under modem and screen load drops faster than the IC expects, triggering an emergency shutdown. It is not a fault in the replacement cell. One full discharge-charge cycle — down to automatic shutdown, then charged uninterrupted to 100% — resets the coulomb counter and removes the cliff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after CPLD-110 installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Coolpad fuel gauge IC stores a learned discharge model from the previous cell. A new 1400mAh cell with a different internal resistance profile will read incorrectly until the IC re-learns the curve. You may see the percentage jump erratically or stall at a fixed number. Run the phone from 100% down to automatic shutdown without interruption, then charge back to full without disconnecting — this gives the IC one complete dataset to recalibrate against the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392108593242,"sku":"BWCS-CPD110SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392108626010,"sku":"BWCS-CPD110SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392108658778,"sku":"BWCS-CPD110SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPD110SL-1.webp?v=1779143797","url":"https:\/\/batteryweb.com\/products\/coolpad-8076d-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
