LG PD233 Replacement Battery 7.4V 500mAh Li-Polymer

Up to 21% off
New arrival
From $24.99 USD $30.99
Shipping calculated at checkout.
Fits LG PD233, PD239, PD251, PD261 photo printers; replaces OEM part P432948-2S.
7.4V, 500mAh lithium-polymer cell delivers steady voltage to the print head heating circuit and paper feed motor.
Connector slides into the battery slot with a single locking tab; orientation is marked on the printer housing.
We bench-tested this cell in a PD233 unit; the BMS accepted the pack on first insertion with no fault cycling.
Charge fully before your first print session — the print head heating cycle and paper motor draw peak current together.

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.

LG PD233 Series — 7.4V Li-Polymer Replacement Battery (P432948-2S)

This is a 7.4V, 500mAh Li-Polymer replacement battery for the LG PD233 portable photo printer. It also fits the PD239, PD251, and PD261 models. The OEM part number is P432948-2S.

  • PD233 / PD239 / PD251 / PD261 compatibility: These four models share the same battery bay dimensions, 7.4V voltage rail, and P432948-2S connector layout. The BMS handshake is identical across the series, so one cell fits all four without modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a PD233 unit. The BMS accepted the cell without fault codes, and the print head heating circuit and paper feed motor both drew current within spec at rated voltage.
  • First print session tip: Charge this battery to 100% before the first print job. The paper feed motor and print head heating element draw peak current simultaneously at the start of a print cycle. A partially charged new cell can trip the BMS on that first draw before a single photo clears the output slot.

Print quality fading mid-print on a new battery

The PD233 print head uses a resistive heating element that requires stable voltage to produce consistent colour density. When the cell voltage sags under load — common in a new Li-Polymer cell that hasn't completed its first full charge cycle — the heat output drops mid-print and the dye transfer becomes uneven. This shows as a visible fade or banding across the photo. Charge the battery fully to 8.4V before the first use to stabilise the cell and prevent this.

Bluetooth pairing lost after battery swap

Removing the battery causes a full power interruption to the PD233's Bluetooth module, which clears its active pairing state. The printer will not reconnect automatically — it sits in standby waiting for a fresh pairing request. On your phone, delete the PD233 from your Bluetooth device list, power the printer on with the new battery installed, then re-pair from scratch. The printer should appear in your device list within 30 seconds of powering on.

Frequently Asked Questions

My LG PD233 won't start printing at all after I put in the new battery — it powers on but nothing happens when I send a photo.

The paper feed motor needs a minimum voltage at the moment of print initialisation to engage. A new Li-Polymer cell fresh out of packaging often sits below 7.2V and the BMS blocks motor current as a protection measure. Charge the battery fully before sending the first job. Once the cell reaches 8.4V, the printer should accept the print command and feed normally.

Photos from my PD233 are coming out with a faded stripe across the middle — print started fine but quality dropped halfway through.

That banding is caused by print head voltage sag. The heating element in the print head needs stable voltage across the full duration of a print cycle, and a partially cycled Li-Polymer cell loses voltage faster under the combined load of the motor and heat element. The result is inconsistent dye transfer in the middle of the sheet where the voltage dip is deepest. Run two full charge-discharge cycles on the battery to condition the cell, then check that the charger brings it to 8.4V before printing.

My LG PD251 prints noticeably slower on battery than it does on USB — is something wrong with this cell?

Nothing is wrong. The PD251 actively reduces paper feed motor speed when running on battery to prevent a high-current motor-start event from tripping the BMS. This is firmware-level behaviour, not a cell defect. Print speed on battery will always be lower than on USB power. If the slowdown is severe enough to cause print errors, check that the battery voltage under load stays above 6.8V — drop below that and the BMS may be throttling more aggressively than normal due to an undercharged cell.
