It fits the G734 (NEXOC734003), G734 (NEXOC734004), and G734 (NEXOC734005) configurations, along with five additional G734 models. If your original cell no longer holds charge or the laptop shuts off under load, this is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG734 series compatibility:\u003c\/strong\u003e\n    All covered models share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS handshake protocol. The thermal and voltage rails are identical across the G734 line, so one cell spec covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, full-load discharge, and BMS communication checks. The protection circuit responded correctly to over-voltage, over-current, and short-circuit events. No BMS lockout was triggered during standard charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the G734:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on a real workload — not idle — then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity curve, clearing the false \"poor health\" warning that appears after any 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 poor battery health immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G734 BIOS reads health data from EEPROM stored on the original battery controller — not from the new cell's actual charge state. When a replacement cell is installed, that EEPROM data is absent or mismatched, so the BIOS flags health as unknown or degraded straight away. This is not a fault with the replacement. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle. After two or three cycles, the health indicator stabilises to reflect the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop cutting out at 20–30% charge shown on the G734\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 voltage curve. The gauge still maps the old cell's cliff point — where voltage drops sharply under CPU and display load — onto the new cell, triggering a shutdown well above true empty. It is not a defective battery. Run two full discharge cycles under real load, letting the system reach hibernate each time, then charge fully. By the third cycle the fuel gauge recalibrates and the cutoff point drops to the correct threshold near 10%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409676206170,"sku":"BWCS-CLP650NB-1","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409676238938,"sku":"BWCS-CLP650NB-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409676271706,"sku":"BWCS-CLP650NB-3","price":117.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLP650NB-1.webp?v=1779580400","url":"https:\/\/batteryweb.com\/products\/nexoc-g734ii-replacement-battery-148v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
