It matches OEM part numbers including 21-92368-01, PC-VP-WP70, and OP-570-76610. Swap it in to restore cordless operation on this mid-range business laptop.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVersa E2000 fitment:\u003c\/strong\u003e\n    The E2000 uses a 14.8V four-cell series architecture with a specific BMS handshake tied to NEC's charge controller. This pack matches that voltage rail and connector pinout exactly — the BMS negotiates charge current with the system board the same way the original cell did.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge-discharge cycles on E2000-class hardware. The BMS held the expected 16.8V peak charge voltage and triggered low-voltage cutoff cleanly at the 12V threshold without dropping prematurely under CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Versa E2000:\u003c\/strong\u003e\n    After fitting this pack, run one full discharge to hibernate-cutoff then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell data and clears the inaccurate health warning that appears on every cell swap in this model.\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 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Versa E2000 BIOS reads health data stored in the battery pack's EEPROM and compares it against the original cell's rated parameters. A new cell ships with fresh EEPROM values that don't match the aged baseline the BIOS expects, so it flags the pack as degraded. This is a firmware interpretation issue, not a cell fault. Run a full discharge-to-hibernate followed by an uninterrupted charge to 100% — the BIOS learn cycle will rewrite its reference baseline and the warning will clear.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down with 20–30% charge still showing on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated against the new cell's actual discharge curve. The E2000's gauge maps percentage to voltage using data from the previous cell, so it misreads remaining capacity — the system hits the hardware low-voltage cutoff while the display still shows charge remaining. The fix is two to three full discharge-to-hibernate and full-charge cycles. After that, the gauge IC recalibrates its curve and the percentage readout will track accurately down to shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410840977498,"sku":"BWCS-NE2000NB-1","price":62.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410841010266,"sku":"BWCS-NE2000NB-2","price":73.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410841043034,"sku":"BWCS-NE2000NB-3","price":81.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NE2000NB-big.webp?v=1779581320","url":"https:\/\/batteryweb.com\/products\/nec-versa-e2000-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
