Battery Care Tips
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
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.

Pax N910 / N900 / N510 — 7.4V Li-ion Replacement Battery (YW-002)
This is a 7.4V, 2600mAh Li-ion battery for the Pax N910, N900, and N510 mobile payment terminals. It fits the battery bay directly and connects to the terminal's onboard charge IC. Voltage and capacity match the OEM spec — 7.4V, 2600mAh (19.24Wh).
- N910, N900, and N510 compatibility: These three Pax terminals share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell fits all three without modification.
- Bench tested on actual hardware: We cycled this battery on the N910 and monitored BMS communication during boot, transaction load, and receipt print events. The protection circuit responded correctly to the printer motor's current spike without tripping an overcurrent fault.
- First transaction cycle before live deployment: After installation, run one complete transaction — including a receipt print — before putting the terminal into service. The N910 maps battery 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 Pax N910 runs a PCI-compliant boot sequence that includes a BMS handshake before the OS fully loads. A new cell sometimes stalls this handshake on the first boot because the BMS has not yet synchronised its state registers with the terminal's charge IC. The fix is straightforward: let the terminal complete its first full boot with the new battery installed and mains power connected. If the terminal hangs at the Pax logo, hold the power button for 10 seconds to force a hard reboot — the second boot attempt completes the handshake in almost all cases.
Battery indicator stuck at 99% after first charge
On a new Li-ion cell, the N910's charge IC enters a top-off phase once the cell reaches approximately 4.15V per cell. During this phase the indicator holds at 99% for an extended period — this is normal charge controller behaviour, not a fault. The indicator moves to 100% once the current tapers below the charge IC's termination threshold, typically at or below 100mA. No action is needed; leave the terminal on charge until the indicator updates on its own.

Frequently Asked Questions
My Pax N910 reboots every time a customer's receipt prints — what's causing that?
The receipt printer motor draws a sharp current spike the moment it fires, and if the battery's state of charge is below roughly 20%, that spike can push the BMS into an overcurrent trip, cutting power instantly. We reproduced this on the bench — the terminal rebooted mid-print consistently below that threshold. Keep the terminal above 30% charge during active service periods. If it reboots even at higher charge levels, check that the battery contacts in the bay are clean and making full contact, since a resistive connection amplifies the voltage sag during the spike.
The terminal sat in a drawer for three months and now won't power on at all — is the battery dead?
Extended storage without a charge top-up can drop a Li-ion cell below the BMS recovery threshold — typically around 2.5V per cell. Below that, the BMS locks output to prevent damage, so the terminal shows no response even when you press the power button. Connect the terminal to mains power via its original charger and leave it for 45–60 minutes without pressing anything. Most BMS circuits have a recovery trickle-charge mode that will bring the cell back above the cutoff threshold; the terminal will then boot normally from the charger.
The N910 feels noticeably warm after processing a high volume of back-to-back transactions — is that a battery issue?
During heavy transaction periods, the terminal is running its display, wireless radio, and receipt printer simultaneously — that combined draw generates heat across both the battery and the main board. Moderate warmth is expected under that load. If the terminal becomes hot to the touch or starts throttling screen brightness, move it to a ventilated surface and avoid stacking it under other equipment. Sustained temperatures above 45°C will accelerate cell capacity fade, so ensure the terminal has airflow on at least two sides during peak service hours.
