Ingenico EFT930 Replacement Battery 3.7V 1800mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Ingenico EFT930, EFT930-B, EFT930-P, EFT930-W and replaces OEM part F26401652.
Outputs 3.7V at 1800mAh capacity — sufficient power for extended transaction sessions without mid-shift recharge.
Connector sits flush into the battery slot with positive contact on top; locking tab secures pack and prevents accidental ejection during heavy use.
We bench-tested this cell on the EFT930 platform and confirmed BMS acceptance after a full boot cycle; charge indicator settled at accurate capacity by transaction two.
After installation, process one complete transaction cycle before live deployment — the terminal maps battery capacity during normal operation and requires at least one full power cycle to calibrate the charge indicator correctly.

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.

Ingenico EFT930 Series — 3.7V Li-ion Replacement Battery (F26401652)

This 3.7V 1800mAh Li-ion battery replaces the original cell in the Ingenico EFT930 series portable payment terminal. It fits the EFT930, EFT930-B, EFT930-P, and EFT930-W variants. Swap it when the original no longer holds enough charge to complete a normal shift on the floor.

  • EFT930 series compatibility: All four EFT930 variants share the same 3.7V cell format, connector pinout, and BMS handshake protocol. One battery covers the full range without modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the EFT930 platform. The BMS accepted the handshake on first boot, the charge IC reached full voltage without flagging errors, and the terminal reported battery status correctly throughout.
  • First deployment tip: After fitting this battery, complete one full transaction cycle — including a receipt print — before taking the terminal live. The EFT930 maps battery capacity during normal operation, not during idle charging, so it needs at least one active power cycle to calibrate the charge indicator correctly.

Terminal rebooting mid-transaction after a battery swap

The EFT930's receipt printer draws a sharp current spike when it fires — this is the single biggest cause of mid-sale reboots after a battery replacement. If the replacement cell's BMS is not yet fully initialised, it can interpret that spike as an overcurrent event and trip the protection circuit, cutting power instantly. The terminal then restarts, which looks like a random crash to the operator. Run two or three complete transaction cycles, including printed receipts, immediately after installation to let the BMS settle its overcurrent threshold.

Terminal not powering on after sitting unused in a drawer

Li-ion cells self-discharge at roughly 2–3% per month. An EFT930 left unused for several months can arrive with a cell voltage below 2.5V — the point where most BMS circuits lock out to prevent damage. The terminal will show no response at all when the power button is pressed. Connect the terminal to its original charger and leave it untouched for at least 30 minutes before attempting to power it on — most charge ICs include a trickle-charge recovery mode that will bring the cell back above the 2.8V BMS re-enable threshold.

Frequently Asked Questions

The battery indicator on my EFT930 has been stuck at 99% since I put the new battery in — is something wrong?

Nothing is wrong. When a new Li-ion cell first reaches full charge, the terminal's charge IC enters a top-off mode and holds the display at 99% while it delivers a low-current finishing charge. This is normal behaviour and clears itself once the battery completes its first full cycle. Use the terminal through a normal transaction session, let it discharge to around 20%, then charge it fully — the indicator will read correctly from that point.

My EFT930 gets noticeably warm during a busy period — is the battery causing that?

The heat is coming from the combined draw of the wireless radio, touchscreen backlight, and receipt printer all running simultaneously. During peak transaction periods, the EFT930 pulls from all three at once, which is the highest sustained load the battery sees. This is normal and does not damage the cell. If the terminal feels hot enough to be uncomfortable rather than just warm, check that the ventilation slots on the casing are not blocked and that the terminal is not enclosed in a tight-fitting case during operation.

The EFT930 powers on but freezes before finishing the boot sequence — could the battery be the cause?

Yes. The EFT930 runs a PCI security boot sequence that draws more current than idle — if the BMS handshake has not completed its first full charge-discharge cycle, the protection circuit can cut power during that surge and the boot screen freezes or loops. Charge the terminal to 100% on a known-good charger before powering it on, then let it complete a full boot without interruption. If the freeze repeats, check that the battery connector is seated fully — a partially connected cell will read a voltage on the charge pins but drop out under the boot-sequence load.
