About this replacement
Pandigital Novel 6 / PRD06E20WWH8 — 3.7V Li-Polymer Replacement Battery (CA397647)
This 3.7V, 1500mAh lithium-polymer cell replaces the original CA397647 battery in the Pandigital Novel 6 e-reader. It fits the PRD06E20WWH8 model variant directly. Capacity figure is taken from product data — 5.55Wh total energy.
- Novel 6 and PRD06E20WWH8 compatibility: Both model designations share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol — one cell covers both. No adapter or wiring modification needed.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Novel 6 platform. The BMS accepted the cell without protection trips, and the e-ink controller initialised normally on first boot.
- Firmware calibration after swap: The Novel 6 firmware tracks coulomb count from the previous cell. After fitting this replacement, charge the device via USB to 100% without interruption — this resets the fuel gauge and stops the percentage indicator from reporting inaccurate readings.
Why the Novel 6 shows low battery immediately after a new cell is installed
Replacement cells ship at storage voltage — typically 3.6V to 3.85V — not full charge. The Novel 6 firmware compares resting voltage against a charge table and flags anything below its full-charge threshold. The device is not defective, and neither is the cell. Connect to USB power and let it charge to 100% before drawing any conclusions about battery health.
Novel 6 not powering on at all after battery replacement
If the cell sat in storage for an extended period, it may have dropped below the minimum boot voltage the Novel 6 requires to initialise — around 3.2V. The device will appear completely dead even with a new battery fitted. Connect the USB charger and leave it for at least 10 minutes before pressing the power button. The BMS needs to accept a trickle charge first, then the main board will receive enough voltage to boot.
