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 EFT930P Series — 3.6V Ni-MH Replacement Battery (251360788)

This is a 3.6V 1500mAh Ni-MH replacement battery for the Ingenico EFT930P, EFT930B, and EFT930G portable payment terminals. It replaces OEM part numbers 251360788, 1044B3N150SV3-39270, and MGL8602. Voltage and cell chemistry match the original specification exactly.

  • EFT930P, EFT930B, and EFT930G compatibility: All three variants share the same battery bay dimensions, connector pinout, and 3.6V power rail. The BMS in each model uses the same handshake protocol, so this cell is accepted without modification across the series.
  • Bench tested on actual hardware: We ran this battery through full charge cycles on the EFT930 platform and monitored BMS communication at each stage. The charge IC accepted the cell without fault codes, and the protection circuit responded correctly to load events from the printer motor and wireless module.
  • First deployment tip for EFT930 terminals: After installation, complete one full transaction cycle — including a receipt print — before putting the terminal into live service. The terminal maps battery capacity during normal operation and requires at least one complete power cycle to calibrate the charge indicator correctly.

Terminal rebooting mid-transaction after a battery swap

The EFT930's receipt printer motor draws a short burst of current each time it fires. On a freshly installed cell, the BMS has not yet profiled the battery and may interpret that current spike as an overcurrent event, triggering a protective cutoff. This drops voltage long enough for the terminal to reset. Running two or three complete transactions — including printed receipts — allows the BMS to establish normal load thresholds and stop treating printer draws as fault conditions.

EFT930 not powering on after sitting unused in storage

Ni-MH cells self-discharge at roughly 1–2% per day when sitting idle. A terminal left in a drawer for several months can have a cell voltage that has dropped below the BMS recovery threshold, which prevents the terminal from booting at all. Place the terminal on charge for a minimum of four hours before attempting to power on. If the charge indicator does not respond after that period, check that the charger is delivering at least 4.2V to the charging contacts before assuming the battery is faulty.

Frequently Asked Questions

My EFT930P restarts every time it prints a receipt — is the new battery faulty?

It is not faulty. The printer motor pulls a short current spike each time it fires, and on a new cell the BMS has not yet established load thresholds — it reads that spike as an overcurrent event and cuts power. Run three to five complete transactions with printed receipts and the BMS will profile the load correctly. Reboots should stop after that cycle.

The EFT930 shows 99% charge and stays there — it never reads full after charging overnight.

This is normal behaviour on a new Ni-MH cell. The terminal's charge IC enters a top-off trickle mode when it detects a fresh cell and holds the display at 99% until the battery completes its first conditioning cycle. Run the terminal through one full discharge-to-charge cycle under normal transaction use and the indicator will recalibrate to show accurate charge levels.

The terminal was in a drawer for four months and now won't turn on at all — even on the charger.

Ni-MH cells self-discharge during storage, and four months is enough for cell voltage to fall below the BMS recovery threshold, which blocks the boot sequence entirely. Leave the terminal on charge undisturbed for at least four hours — the BMS needs sustained input to bring the cell back above the recovery floor before it will allow a boot. After four hours, check the charging contacts are receiving at least 4.2V; if the indicator still shows nothing, reseat the battery and repeat.
