It slots into the battery bay and reconnects the laptop to portable power when the original cell has degraded or stopped holding a charge. Voltage and capacity match the stock specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS530 series compatibility:\u003c\/strong\u003e\n    The S530, S510, S520, and S500 variants share the same 10.8V three-cell battery platform, connector pinout, and BMS communication protocol — which is why a single replacement cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on the S530 platform. The BMS handshake completed correctly, the fuel gauge IC accepted the new cell data, and the pack charged to full capacity without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the S530:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Haier notebooks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Haier S530 BIOS reads health data stored in the battery pack's EEPROM and compares it against an internal baseline built from the old cell's charge history. A brand-new cell has no matching history, so the BIOS flags it as degraded on first boot. This is not a fault with the replacement pack. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — the BIOS resets its learn cycle and the health warning clears within one to two cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly when the gauge still shows 20–30% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual discharge curve. The IC inherited the old cell's voltage-to-capacity mapping, so it misreads the point at which cell voltage collapses under combined CPU and display load. The pack still has usable charge — the gauge is simply wrong. Complete two to three full discharge and charge cycles to let the fuel gauge IC re-map the curve against the new chemistry, and the early shutdowns will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409580261466,"sku":"BWCS-MD4211HB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409580294234,"sku":"BWCS-MD4211HB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409580327002,"sku":"BWCS-MD4211HB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD4211HB-1.webp?v=1779580092","url":"https:\/\/batteryweb.com\/products\/haier-s530-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
