Dell Latitude 12 5290 Compatible Battery 11.4V 4200mAh

Dell Latitude 12 5290 / E5288 — 11.4V Li-ion Replacement Battery (00JWGP)

This is an 11.4V 4200mAh (47.88Wh) Li-ion replacement battery for the Dell Latitude 12 5290 and Latitude E5288 series. It also fits the N013L5290-D1636CN and Latitude 5288 among other models in this line. OEM part numbers covered include 00JWGP, 83XPC, 93FTF, D4CMT, GD1JP, and several others cross-referenced to this cell.

• Latitude 5290 / E5288 platform fit: Both the 5290 and E5288 share the same 11.4V three-cell architecture, connector pinout, and BMS handshake protocol — so a single cell covers the range. The BMS expects a specific EEPROM signature during POST; this replacement carries the correct data to pass that check.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Latitude 5290 unit. The BMS accepted the cell without error flags, charge current tapered correctly at top-of-charge, and the protection circuit tripped at the expected low-voltage cutoff point.
• Post-install calibration on the 5290: After fitting this cell, run one full discharge to hibernate-cutoff, 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 this platform — it is not a fault with the replacement cell.

BIOS reporting battery health as poor immediately after replacement

The Latitude 5290 stores capacity and cycle data in the outgoing cell's EEPROM. When a new cell goes in, the BIOS compares the fresh EEPROM against its stored discharge history and flags a mismatch as poor health. This is a firmware read issue, not a cell defect. One full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough data to rewrite its learned values. After that cycle, the health indicator should return to Normal in Dell Power Manager.

Laptop shuts down at 20–30% shown on the fuel gauge

When the CPU boosts under load and the display is at full brightness, the 5290 draws a current spike the fuel gauge IC has not yet mapped against the new cell's actual discharge curve. The cell voltage drops below the BMS protection threshold before the reported percentage reaches zero, triggering an immediate shutdown. This is a fuel gauge calibration gap, not a weak cell. Run two to three full discharge-recharge cycles and the gauge IC will recalibrate its curve — shutdowns should stop occurring above 10% after that.
