Nextbook NXW10QC32G Replacement Battery 3.7V 6600mAh

Nextbook NXW10QC32G — 3.7V Li-Polymer Replacement Battery (1ICP3/79/123 2S1P)

This 3.7V, 6600mAh lithium-polymer battery replaces the original pack in the Nextbook NXW10QC32G 10-inch tablet. It matches the OEM part number 1ICP3/79/123 2S1P and fits the physical footprint at 157.15 × 123.32 × 3.14 mm. Capacity is rated at 24.42Wh — use the product data figure, not estimates from third-party listings.

• NXW10QC32G and Nextbook 10" compatibility: Both model variants use the same connector pinout, voltage rail, and BMS handshake. The 1ICP3/79/123 2S1P part number covers the full range — no adapter or wiring modification needed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the NXW10QC32G mainboard. The BMS accepted the pack without error flags, and the charge IC completed a full CV/CC cycle to 4.2V without thermal events.
• Fuel gauge recalibration after installation: Run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC against the new cell's actual capacity curve and corrects inaccurate percentage readings that commonly appear after a battery swap.

Nextbook NXW10QC32G shutting down at 15–25% remaining

The NXW10QC32G draws a combined load from the 10-inch display backlight and the WiFi radio simultaneously. Under that combined draw, the cell voltage drops faster than the fuel gauge IC can track — especially on a new cell the gauge hasn't calibrated to yet. The tablet's protection circuit interprets the voltage dip as a critically low state and forces shutdown before the displayed percentage reaches zero. One complete discharge-to-shutoff cycle followed by an uninterrupted charge to 100% aligns the gauge to the new cell and eliminates the premature cutoff.

Battery percentage jumping or reading wrong after swap

The fuel gauge IC on the NXW10QC32G mainboard stores capacity data calibrated to the old, degraded cell. When a new cell goes in, the IC compares incoming voltage curves to outdated reference data — this produces erratic jumps, sudden drops, or a stuck percentage on screen. The fix is not a software update. Discharge the tablet fully until it shuts itself off, then charge it in one uninterrupted session to 100% at the standard 5V input. After that cycle, the IC recalibrates and reported percentage tracks actual cell voltage correctly.
