About this replacement
Dell XPS 10 — 7.4V Li-Polymer Replacement Battery (JD33K / 0FP02G)
This is a 7.4V, 3600mAh (26.64Wh) Li-Polymer replacement battery for the Dell XPS 10 tablet. It fits the tablet unit directly, restoring portable power to the 10-inch Windows display when the original cell has degraded. OEM part numbers JD33K and 0FP02G both cross-reference to this battery.
- XPS 10 tablet compatibility: The XPS 10 uses a dedicated battery in the tablet display unit, separate from any keyboard dock battery. This cell matches the flat Li-Polymer form factor at 250.63 × 116.02 × 3.39mm, the correct 7.4V nominal rail, and the BMS handshake the Dell EC firmware expects on first charge.
- Bench tested on actual hardware: We ran this cell through charge, idle draw, and load cycles on the XPS 10 platform. The BMS negotiated correctly with the Dell EC, and the fuel gauge initialised without fault codes on the test unit.
- First-cycle calibration on the XPS 10: After installation, run the tablet down to the hibernate cutoff under normal use, then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference sweep against the new cell chemistry and clears the inaccurate battery health warning that appears in the Dell BIOS after a cell swap.
BIOS reporting poor battery health immediately after fitting the new cell
The Dell BIOS reads health data from the battery's EEPROM, which ships with factory default values rather than live cycle data. On first boot, those defaults often read as degraded relative to what the BIOS expects. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the BIOS battery learn cycle. After that cycle, the health indicator should resolve to normal.
XPS 10 shutting down with 20–30% charge still shown on screen
This happens when the fuel gauge IC has not yet calibrated its state-of-charge model against the new cell. The displayed percentage drifts high, so the system hits the actual low-voltage cutoff while still showing residual charge. The cell voltage drops below the safe threshold before the gauge catches up. Run two full discharge-to-hibernate and charge-to-100% cycles — after the second cycle, the gauge recalibrates and the shutdown point should align with the displayed percentage at or below 5%.
