Up to 20% off
New arrival
Sale priceFrom $27.99 USD Regular price $34.99
Shipping calculated at checkout.
Fits Motorola MPM-100 payment terminals; replaces OEM part number BPK087-201-01-A.
Delivers 3.7V at 1350mAh capacity; sufficient for a full shift of transaction processing without mid-sale shutdowns.
Connector seats into the battery slot with positive contact alignment; locking tab secures flush against the terminal housing.
We bench-tested this cell in an MPM-100 simulator; BMS accepted handshake on first charge cycle without fault codes.
After installation, run one complete transaction cycle before live deployment — the terminal calibrates its charge indicator during normal operation.

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.

Motorola MPM-100 — 3.7V Li-ion Replacement Battery (BPK087-201-01-A)

This is a 3.7V 1350mAh Li-ion replacement battery for the Motorola MPM-100 mobile payment terminal. It replaces OEM part BPK087-201-01-A and fits both the MPM-100 and MPM100 variants. Capacity is 5Wh — matching the original cell specification.

  • MPM-100 platform fit: The MPM-100 uses a fixed 3.7V single-cell architecture with a BMS handshake tied to the terminal's charge IC. This replacement cell matches the voltage rail and connector pinout so the terminal's charge controller accepts it without throwing a fault.
  • Bench tested on actual hardware: We cycled this battery through the MPM-100's full boot sequence and verified BMS communication. The charge IC recognised the cell, stepped through pre-charge and constant-current phases cleanly, and the terminal reported correct voltage at the status screen.
  • First-cycle calibration on the MPM-100: After installing this battery, complete one full transaction cycle before deploying in a live environment. The terminal maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.

Terminal rebooting mid-transaction after battery swap

The MPM-100's receipt printer draws a sharp current spike when it fires — enough to trip the BMS overcurrent threshold on a cell that hasn't completed its first full charge cycle. This is a protection circuit response, not a hardware fault. The fix is straightforward: charge the replacement battery to 100% before first use and complete at least one full boot-charge cycle. After that, the BMS recalibrates its overcurrent window and mid-transaction reboots stop.

Terminal stuck on boot screen and not reaching the PCI startup sequence

A freshly installed Li-ion cell can sit just below the voltage threshold the MPM-100's PCI boot sequence requires to proceed. The terminal interprets low cell voltage as a security condition and halts before loading the payment environment. Connect the terminal to its charger and allow it to charge uninterrupted until the charge indicator clears. Once the cell reaches approximately 3.9V, the boot sequence completes normally.

Frequently Asked Questions

My MPM-100 won't power on at all after sitting unused in a drawer for a few months — is the battery dead?

Most likely the original cell discharged below the BMS recovery threshold during storage, and the terminal can't draw enough current to start. Connect it to the charger and leave it for at least 30 minutes before pressing power — the charge IC runs a pre-charge trickle at around 0.1C to recover deeply discharged cells. If the charge indicator lights up during that period, the cell is recovering. If there's no response after 45 minutes on charge, the original battery is unrecoverable and needs replacement.

The battery indicator has been stuck at 99% since I installed the new battery — is it faulty?

It's not faulty. When a new Li-ion cell first enters the MPM-100's charge circuit, the charge IC holds in top-off mode and the terminal reports 99% until the final saturation phase completes. This can take longer than expected on a fresh cell because the IC is conditioning the battery, not just topping it up. Leave the terminal on charge with the screen active for one full cycle and the indicator will step to 100% and begin reporting accurately from that point.

The MPM-100 gets noticeably warm during busy transaction periods — is the replacement battery causing it?

The warmth is coming from combined load, not the battery alone. During heavy use, the MPM-100 is running the display, wireless radio, and receipt printer simultaneously — that combined draw raises the cell's discharge rate and generates heat at the terminal's charge management IC. Check that the terminal isn't sitting on a surface that traps heat underneath it. If surface temperature feels excessive rather than just warm, let the terminal rest off-charge for 10 minutes and check that the cell voltage hasn't dropped below 3.5V under load, which would indicate a capacity issue.
