About this replacement
RCA RCT6272W23 7" Tablet — 3.8V Li-Polymer Replacement Battery (PT3867103)
This 3.8V, 3650mAh lithium-polymer battery replaces part number PT3867103 in the RCA RCT6272W23 7-inch Android tablet. It restores power to a tablet that no longer holds a charge or shuts down unexpectedly. Voltage, capacity, and connector position match the original cell.
- RCT6272W23 platform fit: The RCT6272W23 uses a flat Li-Polymer pouch cell rated at 3.8V nominal with a three-pin flex connector. This replacement matches that connector pinout and cell thickness at 3.80mm — so the rear housing closes flush without flexing the display assembly.
- Bench tested on actual hardware: We ran this cell through the RCT6272W23 charge IC and confirmed the BMS accepted the charge handshake without throwing a fault. The cell drew current at the expected rate through the full charge cycle with no thermal runaway.
- Fuel gauge IC reset after installation: After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100% before using it again. The RCT6272W23 fuel gauge IC calibrates against the old cell's profile — one full discharge-to-charge cycle resets it against the new cell and clears the inaccurate percentage readings that appear right after a swap.
RCT6272W23 shutting down at 15–25% remaining
This happens when the cell voltage drops faster than the fuel gauge predicts under combined load — display backlight plus active WiFi is the usual trigger on this tablet. The old cell's voltage curve is stored in the fuel gauge IC, so a new cell with a slightly different curve causes early cutoff. One complete discharge cycle forces the IC to relearn the new cell's voltage cliff. After that cycle, shutdowns at 15–25% stop.
Fast charging not available after fitting a replacement cell
The RCT6272W23 charge IC needs at least one completed charge cycle before it negotiates a higher current rate with the charger. On the first charge after a swap, the IC defaults to a conservative trickle profile as a safety check against the new cell. Plug in using the original adapter and let the tablet charge fully without interruption. After one full accepted cycle, the charge rate returns to normal.
