Fits Polaroid BDL0948PCE tablet; replaces OEM part number SR299198P.
3.7V, 3300mAh lithium-polymer cell restores full charge capacity to the tablet.
Connector seats flush into the original battery slot with standard locking tab engagement.
Bench testing showed clean BMS initialization on first insertion; voltage curve tracked nominal discharge profile.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell and resolves inaccurate percentage display that appears after a swap.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My Polaroid BDL0948PCE tablet is showing 80% battery right after I installed the new battery — is the percentage stuck or wrong?

The fuel gauge IC on the BDL0948PCE was calibrated to the old cell's discharge curve, so it gives inaccurate readings on a fresh replacement. The fix is one full recalibration cycle: discharge the tablet completely until it shuts off on its own, then charge it uninterrupted to 100% without using the tablet during that charge. After one complete cycle the fuel gauge re-maps to the new cell and percentage accuracy returns. Do not interrupt the charge partway through — a partial cycle does not reset the calibration.

The BDL0948PCE tablet gets noticeably warm while charging with the new battery — should I be concerned?

Warmth during the constant-current phase of charging is normal when a charge IC encounters a new cell. The IC drives current at a higher rate early in the cycle, which generates heat in both the cell and the charge circuit. We measured surface temperatures on the bench and they stayed within the normal operating range for Li-Polymer cells of this capacity. If the tablet feels hot to the touch rather than warm, or if charging stops and restarts repeatedly, check that the charger output matches the tablet's rated input — use the original charger or one rated at the same voltage and current.

Battery percentage on my BDL0948PCE is dropping much faster than expected from 100% down to around 60%, then slowing down — what causes that?

This is fuel gauge drift, not actual capacity loss. The discharge curve the gauge uses does not match the new cell's chemistry profile until the IC has observed a full cycle. The gauge over-reports voltage drop in the upper range and under-reports it in the mid-range, which makes the percentage fall fast at first then appear to stabilise. Run a single full discharge to automatic shutoff followed by a complete uninterrupted charge to 100%. After that one cycle the gauge re-references the new cell and the percentage drop should even out across the full range.
