It fits via OEM part numbers DR36 and DR36S. Capacity is 45.6Wh, matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVisionBook Plus and ND1 Series compatibility:\u003c\/strong\u003e\n    These models share the same 12V battery rail, connector pinout, and BMS handshake protocol. The DR36 and DR36S part numbers cover the full group — the BMS recognises the same cell signature across all listed variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and load cycles on a VisionBook Plus platform. The BMS accepted the cell without fault flags, charge termination triggered correctly at capacity, and voltage held stable under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after installation:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. Ni-MH cells in this platform require this to reset the BIOS battery learn cycle — skipping it leaves an inaccurate health warning in the system.\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 swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VisionBook BIOS stores EEPROM data from the previous cell and compares the new cell against it on first boot. A fresh Ni-MH replacement will almost always trigger a poor health or unrecognised battery warning at this point. This is not a fault with the new cell. Run one complete discharge-to-hibernate cycle followed by an uninterrupted full charge, and the BIOS will rewrite its reference data against the new cell's actual capacity curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down suddenly with 20–30% charge still showing on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The gauge reads the old cell's discharge profile, so it misreports remaining capacity. When combined CPU and display draw pulls the cell into high-load territory, the actual cell voltage drops below the BMS cutoff before the gauge reaches zero. Two to three full discharge-to-hibernate and charge-to-100% cycles recalibrate the fuel gauge IC against the new cell. After calibration, the cutoff should align with the display reading dropping below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410857820250,"sku":"BWCS-DR36HB-1","price":89.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410857853018,"sku":"BWCS-DR36HB-2","price":105.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410857885786,"sku":"BWCS-DR36HB-3","price":118.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DR36HB-big.webp?v=1779581376","url":"https:\/\/batteryweb.com\/products\/hitachi-visionbook-plus-4360-replacement-battery-12v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
