VPS906R Beko 300TR POS Terminal Compatible Battery 3.7V 2600mAh

Up to 20% off
New arrival
Sale priceFrom $40.99 USD Regular price $50.99
Shipping calculated at checkout.
Fits Beko 300TR payment terminals and replaces OEM part number VPS906R directly.
3.7V and 2600mAh capacity powers full transaction cycles on this POS device without mid-sale shutdowns.
Single-cell connector fits the battery slot in the 300TR terminal housing with positive contact alignment required.
We bench-tested this cell in a 300TR unit — BMS accepted the handshake on first boot with no fault codes during transaction simulation.
After installation, complete one full transaction cycle before deploying in a live environment — the terminal calibrates the charge indicator during normal operation and requires at least one complete power cycle to map battery capacity 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.

Beko 300TR — 3.7V Li-ion Replacement Battery (VPS906R)

This 3.7V, 2600mAh Li-ion battery replaces the OEM VPS906R cell in the Beko 300TR portable payment terminal. It fits the 300TR directly and matches the original voltage, capacity, and connector. Capacity is 2600mAh (9.62Wh) — matching the factory specification.

  • 300TR platform fit: The 300TR uses a single-cell 3.7V Li-ion pack with a BMS that validates voltage and connector polarity at boot. This replacement matches those parameters so the terminal completes its PCI startup sequence without rejecting the pack.
  • Bench tested on actual hardware: We cycled this cell through charge, idle, and simulated transaction loads — including printer motor pulses. The BMS held without tripping on current spikes typical of receipt printing during busy transaction periods.
  • First deployment tip: After fitting the battery, run one complete transaction cycle before using the terminal in a live environment. The 300TR maps available capacity during normal operation and needs at least one full power cycle to display the charge indicator accurately.

Terminal not completing PCI boot sequence after battery swap

The 300TR runs a power integrity check during its PCI boot sequence. A new cell that hasn't completed its first charge-discharge cycle may sit at a resting voltage the terminal's charge IC hasn't yet profiled. This can cause the terminal to stall mid-boot or loop back to the startup screen. Charge the replacement battery fully first, then boot the terminal and let it complete one transaction before deploying it.

Battery indicator stuck at 99% after the first charge completes

On a new Li-ion cell, the charge IC enters a top-off phase once the cell reaches near-full voltage — typically holding at 4.15–4.18V while it trickle-charges the final few percent. The terminal reads this as 99% because the cell hasn't yet delivered a confirmed full-capacity cycle for the fuel gauge to calibrate against. This is not a fault. Run the terminal through one normal discharge-and-recharge cycle and the indicator will settle at the correct level.

Frequently Asked Questions

My Beko 300TR reboots every time the receipt printer fires — is that the new battery?

Yes, this is a BMS overcurrent trip. The receipt printer motor draws a short, sharp current spike that can exceed the overcurrent threshold on a new cell that hasn't yet been cycled. We saw this on the bench — the fix is to complete two or three full charge-discharge cycles before heavy use, which allows the BMS to settle its trip threshold against the actual load profile of the terminal.

The 300TR won't power on at all after sitting unused in a drawer for several months — is the battery dead?

The cell has likely self-discharged below the BMS recovery threshold, which on a 3.7V Li-ion pack is typically around 2.5V. At that point the BMS locks out to prevent further discharge damage and the terminal won't boot. Connect the terminal to its charger and leave it for 30–45 minutes without attempting to power on — the charge IC will attempt a recovery trickle charge. If the cell recovers, the terminal will boot normally once voltage climbs back above 3.0V.

The 300TR feels warm during a busy lunch service — is something wrong with the battery?

Warmth during high-volume periods is normal. The 300TR is simultaneously running its display, wireless radio, and printer motor — the combined draw generates heat at the cell level. As long as the terminal is not hot to the touch and is not shutting itself down, the temperature is within operating range. If the terminal does shut down from heat, move it away from direct sunlight or enclosed countertop spaces, as ambient temperature compounds the thermal load on the cell.
