It replaces the original cell when the notebook no longer holds a charge or fails to power on without the adapter plugged in. Voltage and connector match the OEM specification for these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDD3 Plus and ZX6-CP5S platform fit:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — that is why a single cell covers the whole group. The BIOS on each reads the same EEPROM identifiers, so the battery registers correctly without firmware workarounds.\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 a ZX6-CP5S unit. The BMS communicated current state-of-charge data correctly to the OS fuel gauge, and charge acceptance reached full capacity without cutoff anomalies at any stage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Hasee notebooks:\u003c\/strong\u003e\n    After fitting, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100% without using the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after fitting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the BIOS carries EEPROM data from the old, degraded cell and applies it to the new one before any learn cycle runs. The health flag is calculated against the previous cell's recorded capacity, not the replacement's actual capacity. Running one full discharge-to-hibernate followed by an uninterrupted full charge gives the BIOS enough data to write new EEPROM values. After that cycle, the health status updates and the warning clears on its own.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a gauge error. When the CPU and display are both under load, the cell's voltage drops faster than the fuel gauge IC can track — the laptop hits the BMS low-voltage cutoff while the OS still shows charge remaining. It is common on aged cells but can also appear on a new cell that has not completed a calibration cycle yet. Run one full discharge to hibernate cutoff, then charge to 100% without interruption — the fuel gauge IC recalibrates against the new cell's actual voltage curve and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409682923610,"sku":"BWCS-CLB500NB-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409682956378,"sku":"BWCS-CLB500NB-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409682989146,"sku":"BWCS-CLB500NB-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLB500NB-1.webp?v=1779580399","url":"https:\/\/batteryweb.com\/products\/hasee-dd3-plus-replacement-battery-108v-4200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
