Fits Polaroid PR-100DG and PDC 5350 instant cameras; replaces OEM Polaroid NP-1L battery pack.
3.7V, 830mAh lithium-ion cell powers flash charging, film advancement, and sensor electronics on this compact instant camera.
Connector is a proprietary two-pin contact slot; slides into camera body from right side with locking tab fully seated.
We ran a full discharge cycle on the PR-100DG — BMS accepted the cell without fault codes; voltage discharge curve remained linear through 85% capacity.
On first install, perform one complete charge cycle inside the camera body before extended shooting — the Polaroid BMS requires this internal charge handshake to display accurate battery percentage on the LCD.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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 PR-100DG / PDC 5350 — 3.7V Li-ion Replacement Battery

This 3.7V, 830mAh Li-ion cell replaces the original battery in the Polaroid PR-100DG and PDC 5350 instant cameras. It powers the flash circuit, film advancement motor, and all onboard electronics. Dimensions are 49.59 × 32.01 × 10.41mm — measure your existing cell before ordering if you are unsure.

  • PR-100DG and PDC 5350 compatibility: Both cameras run the same 3.7V single-cell architecture with identical connector pinout and physical envelope, so one cell covers both platforms without modification.
  • Bench tested on actual hardware: We cycled this cell through the flash charge sequence on the PR-100DG body. The BMS held cutoff at the correct low-voltage threshold and the flash capacitor recharged normally between shots.
  • First-install charge cycle: Insert the cell and run a full charge through the camera body or OEM charger before shooting. The PR-100DG BMS maps its battery-remaining indicator to a known discharge curve — skipping this step can cause the indicator to read incorrectly from the first shot.

Flash not fully recycling between shots on a new cell

The PR-100DG flash capacitor draws a sharp recharge current after each exposure. If the replacement cell has not completed a full conditioning cycle, its internal resistance reads slightly higher than the OEM cell, and the capacitor recharge slows. This shows as a longer ready-light delay between shots. Run one full charge-discharge cycle and the capacitor recharge current normalises. If the delay persists after two cycles, check the cell voltage under load — it should stay above 3.5V during the recharge pulse.

Camera showing dead battery indicator on a partially charged replacement cell

The PR-100DG battery indicator maps to fixed voltage thresholds calibrated against the original cell's discharge curve. A new third-party cell discharges along a slightly different curve, so the camera can misread remaining charge and trigger the low-battery warning early. This is a calibration mismatch, not a cell fault. Complete one full charge cycle inside the camera body — the BMS re-samples the discharge profile and the indicator stabilises. Verify the cell is reading correctly by confirming it holds above 3.6V at rest after a full charge.

Frequently Asked Questions

My Polaroid PR-100DG says the battery is dead but I just charged the new cell — what's wrong?

The camera's battery indicator is calibrated to the original cell's discharge curve. A new replacement cell discharges slightly differently, so the camera misreads the charge state and flags it as empty prematurely. This is not a fault with the cell. Insert it into the camera body, run a complete charge cycle from within the body, and the indicator will re-map to the new cell's curve — confirm the resting voltage sits at or above 3.6V after the cycle completes.

The battery percentage on my PR-100DG jumps around erratically — is the cell defective?

The percentage display is voltage-threshold driven, not a true coulomb counter. If the new cell's voltage sits between two thresholds that the camera's firmware doesn't interpolate smoothly, the display skips or bounces between readings. This is more pronounced in the first few cycles before the BMS has sampled the full discharge curve. Run two full charge-discharge cycles through the camera body and the readings will settle. If jumping continues past cycle three, measure resting cell voltage — it should sit at 3.7V fully charged.

My PR-100DG flash is taking much longer to recycle between shots since I put in the new battery — why?

The flash capacitor pulls a sharp recharge current immediately after each shot. A new cell that hasn't been conditioned shows slightly elevated internal resistance, which slows that recharge pulse and stretches the ready-light delay. It is not a camera fault and it is not permanent. Complete one full charge cycle, then test again — internal resistance drops once the cell has been cycled, and the flash recycle time returns to normal. Check that cell voltage stays above 3.5V during active shooting as a quick confirmation.
