About this replacement
BLU TouchBook G7 — 3.7V Li-Polymer Replacement Battery (C948730300P)
This 3.7V, 2600mAh (9.62Wh) Li-Polymer battery replaces OEM part C948730300P in the BLU TouchBook G7. It fits the P240u, TouchBook G7 7.0" 3G, and BT-E003 variants. Swap this in when the original cell no longer holds a charge or the tablet shuts off unexpectedly under load.
- TouchBook G7 and P240u platform: These models share the same flat Li-Polymer cell format, connector pinout, and charge IC handshake. The C948730300P part number covers all listed variants — no adapter or wiring change needed.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the TouchBook G7 platform. The BMS accepted charge negotiation correctly and hit cutoff at the expected 4.2V upper threshold without tripping protection.
- Fuel gauge reset after installation: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100% without using the tablet. This forces the fuel gauge IC to calibrate against the new cell and corrects the inaccurate percentage readings that appear immediately after a swap.
BLU TouchBook G7 shutting down at 15–25% battery remaining
The TouchBook G7 drives the display backlight and WiFi radio simultaneously during video or browsing sessions. That combined load pulls a current spike the aging fuel gauge IC can't accurately track. The voltage drops faster than the reported percentage suggests, and the BMS trips the cutoff before the display reads zero. After installing the new cell, run one full calibration cycle — discharge to automatic shutoff, then charge to 100% — and the shutdowns at false-high percentages typically stop.
Fast charging not available after battery swap on the TouchBook G7
Some USB charge controllers on BLU tablets require at least one completed charge cycle before they negotiate above standard 5V 500mA input. After installing a new cell, the controller may default to slow charge on the first cycle as a safety measure. Plug into a compatible charger and let the first charge run to 100% uninterrupted. On the second charge, fast charge negotiation typically resumes at the correct voltage and current.
