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.

Eservice Smart D220 — 3.8V Li-Polymer Replacement Battery (IS707)

This 3.8V, 3000mAh Li-Polymer battery replaces the original IS707 cell in the Eservice Smart D220 payment terminal. It fits the Smart D220 directly, using the same connector and BMS communication protocol as the factory unit. Capacity is 3000mAh (11.4Wh), sourced to match OEM specifications.

  • Smart D220 fitment: The Smart D220 uses a single-cell Li-Polymer pack at 3.8V nominal. The IS707 form factor — 74.60 x 53.70 x 4.70mm — occupies the full battery bay. Any deviation in thickness or connector pinout will cause BMS rejection at boot, so physical and electrical match both matter here.
  • Bench tested on actual hardware: We cycled this cell through card-read, receipt print, and wireless transaction sequences. The BMS held steady through the combined current draw of the printer motor and radio stack without tripping overcurrent protection.
  • First deployment tip: After fitting this battery, complete one full transaction cycle before putting the terminal into live service. The Smart D220 maps battery capacity during normal operation and requires at least one complete power cycle to calibrate the charge indicator correctly.

Terminal not completing PCI boot sequence after battery swap

The Smart D220 runs a PCI compliance check during startup that includes a battery handshake. A new cell that hasn't completed a full charge-discharge cycle may report state-of-charge data the terminal treats as out of range. This causes the boot sequence to stall or loop before reaching the payment screen. Charge the battery to 100%, power the terminal off cleanly, then restart — one full boot-charge cycle usually clears the handshake flag.

Terminal rebooting mid-transaction during receipt printing

The receipt printer motor draws a short burst of current well above the idle load of the display and wireless radio. On a degraded or partially discharged battery, this spike can push cell voltage below the BMS undervoltage threshold, triggering an immediate protection cutoff — which looks like a reboot. If this happens consistently, check that the cell is above 3.6V before high-volume transaction periods. A cell sitting at 3.5V under idle load will not hold voltage through a printer motor start surge.

Frequently Asked Questions

My Smart D220 was sitting unused in a drawer for a few months and now won't power on at all — is the battery dead?

Extended storage without a top-up charge can pull a Li-Polymer cell below the BMS recovery threshold, typically under 3.0V. At that point the BMS locks the output to protect the cell, and the terminal shows nothing when you press the power button. Connect the terminal to its charger and leave it for 30–45 minutes before attempting to power on — most BMS controllers will begin a trickle recovery charge and unlock the output once the cell reaches 3.2V.

The charge indicator has been stuck at 99% since I put the new battery in — is something wrong with the cell?

Nothing is wrong. When a new Li-Polymer cell first enters the charger, the charge IC switches to top-off mode at high state-of-charge and pulses small amounts of current until the cell voltage stabilises at exactly 4.2V. This can take longer than the terminal's display expects, so the indicator stalls at 99%. Run the terminal through a normal transaction cycle and let the battery discharge slightly — the charge IC will reset its calibration on the next charge and the indicator will read correctly.

The Smart D220 feels noticeably warm after a busy period of back-to-back transactions — is the battery overheating?

Under sustained load — display on, wireless active, and the printer firing repeatedly — the combined draw on a single 3.8V Li-Polymer cell generates heat that the terminal's slim chassis can't dissipate quickly. This is normal within limits. If the terminal is too hot to hold comfortably or shuts down on its own, let it rest for five minutes with the screen off before continuing. If shutdowns persist, measure open-circuit cell voltage after cooling — it should read at least 3.7V at rest; anything below that indicates the cell is not recovering charge correctly between cycles.
