About this replacement
Pandigital Novel 9 / Supernova DLX 8 — 3.7V Li-Polymer Replacement Battery (BP-PO2-11/3400CL)
This 3.7V, 3000mAh lithium-polymer cell replaces the original battery in the Pandigital Novel 9 (R90L200) and Supernova DLX 8 e-readers. It matches the OEM dimensions at 101.60 x 66.70 x 4.20mm, so it seats flat inside the chassis without lifting the back cover. Swap this in when the original no longer holds a charge or the device shuts off mid-session.
- Novel 9 and Supernova DLX 8 compatibility: Both devices share the same battery bay dimensions, connector pinout, and 3.7V supply rail, which is why one cell covers the full model range. The BMS communicates charge state to the same firmware stack across R90L200 and DLX 8 variants.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Novel 9 platform. The BMS accepted the cell without fault codes, charge termination triggered correctly at 4.2V, and the firmware reported accurate state-of-charge throughout.
- Post-swap charging tip for e-reader firmware: After installation, connect via USB and charge through one complete cycle before use. The Novel 9 firmware recalibrates its battery percentage display against a full charge cycle — skipping this step causes the indicator to read inaccurately from the first boot.
Why the Novel 9 shows low battery immediately after a new cell is installed
Replacement cells ship at storage voltage, typically 3.6–3.8V, not at full charge. The Novel 9 firmware reads this as a partially depleted battery and flags it immediately on the status bar. This is not a fault with the cell — it is the firmware comparing the resting voltage against its calibration table. Connect the charger before the first boot and allow the cell to reach 4.2V before powering on.
Page turn response slows down before the battery indicator shows critical
The e-ink display on the Novel 9 draws a short high-current pulse to refresh each page. As cell voltage drops below roughly 3.5V, that pulse takes longer to complete, which adds a visible lag to every page turn. The battery percentage indicator often still reads 15–20% at this point because the firmware's voltage-to-percentage curve is not linear at the low end. If response feels sluggish, check actual resting voltage with a multimeter — anything below 3.5V means the cell needs a charge cycle, regardless of what the screen shows.
