About this replacement
Pandigital Novel Tablet Color (R7T40WWHFI) — 3.7V Li-Polymer Replacement Battery (MLP3595100)
This 3.7V 3200mAh Li-Polymer cell replaces the original MLP3595100 battery in the Pandigital Novel Tablet Color (model R7T40WWHFI). It fits the flat-cell cavity behind the rear panel and connects via the stock JST-style harness. Capacity matches the factory spec at 11.84Wh.
- Novel Tablet Color and R7T40WWHFI fit: Both model designations share the same physical chassis, battery bay dimensions, and 3.7V single-cell power rail. The connector pinout and BMS handshake protocol are identical across both, so one cell covers both.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Novel Tablet Color platform. The BMS accepted the new cell without fault flags, voltage regulation held steady at the processor rail, and the display backlight held consistent brightness through the discharge curve.
- Post-swap charging on the Novel Tablet Color: After installing, connect the device to its USB charger and run a complete charge cycle before powering on. The Novel Tablet Color firmware recalibrates its battery percentage gauge only during a full charge — skipping this step causes the indicator to report inaccurate readings from the first boot.
Why the Novel Tablet Color shows 0% immediately after a new cell is fitted
Replacement cells ship at storage voltage — typically 3.6V to 3.85V — which sits inside the normal operating range but below the firmware's calibration reference. The Novel Tablet Color reads the new cell as uncalibrated and defaults the gauge to zero. This is a firmware behaviour, not a cell fault. Plug into USB power before the first boot, let the indicator climb to 100%, then power on normally.
Page turns becoming sluggish after a battery swap
Slow e-ink refresh after a swap usually points to the processor running under a suppressed voltage rail. If the new cell was stored at low voltage, the BMS may throttle output current to protect the cell during initial recovery. The display controller draws a brief high-current pulse to drive the e-ink panel — under a restricted rail, that pulse takes longer to resolve. Charge the device to at least 3.9V per cell before extended use, and the refresh speed returns to normal.
