About this replacement
Polaroid BDL0948PCE — 3.7V Li-Polymer Replacement Battery (SR299198P)
This is a 3.7V, 3300mAh lithium-polymer battery for the Polaroid BDL0948PCE tablet. It replaces part number SR299198P and fits the original battery bay without modification. Use it when the existing cell no longer holds a charge or the tablet fails to power on.
- BDL0948PCE platform fit: The BDL0948PCE uses a single-cell 3.7V Li-Polymer pack with a low-profile 3.30mm form factor. This replacement matches the voltage rail, physical dimensions (113.00 × 74.70 × 3.30mm), and connector orientation the charge IC expects.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the BDL0948PCE platform. The BMS accepted the new cell without faults, and the charge IC progressed normally through constant-current and constant-voltage phases to full termination.
- Fuel gauge reset after installation: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC a complete reference cycle against the new cell and corrects inaccurate percentage readings that commonly appear after a swap.
Tablet shutting down at 15–25% remaining after battery swap
This is a voltage cliff issue. Under combined display and Wi-Fi load, cell voltage drops faster than the fuel gauge predicts, and the protection circuit triggers a shutdown before the reported percentage reaches zero. The fuel gauge is still calibrated to the old cell's discharge curve, so its percentage readings are unreliable on the new cell. Run one full cycle — discharge to auto-shutoff, then a full uninterrupted charge — and the fuel gauge re-maps against the new cell. After that cycle, shutdowns at 15–25% typically stop.
Fast charging not available after replacing the BDL0948PCE battery
Fast charge or USB-PD negotiation on the BDL0948PCE requires the charge IC to complete at least one accepted charge cycle on the new cell before it enables higher charge rates. If fast charge is missing immediately after a swap, plug in using the original charger and let the tablet charge fully without interruption. The charge IC logs the cycle on completion. Disconnect, allow the screen to turn on, then reconnect — fast charge should re-engage at that point.
