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.

Zebra RW420 / L405 — 7.4V Li-ion Replacement Battery (AK17463-005)
This is a 7.4V, 6800mAh Li-ion battery for the Zebra RW420 and L405 mobile receipt and label printers. It replaces OEM part numbers AK17463-005 and CT17102-2. If your original battery is swelling, not holding charge, or the printer shuts off mid-job, this is the direct swap.
- RW420, L405, and RW420 EQ compatibility: These three models share the same 7.4V battery bay, connector pinout, and BMS communication protocol. The printer's firmware reads the battery's cell state on boot — same voltage rail means no handshake mismatch across the supported models.
- Bench tested on actual hardware: We cycled this battery through full charge and discharge on RW420 hardware. The BMS held a stable voltage output through sustained thermal head activation and paper feed motor loads, with no unexpected cutoff events during the test sequence.
- First-use calibration tip: After installing, charge fully, then print five test receipts before field deployment. The paper feed motor draws a short current spike on each cycle — running that sequence lets the BMS log the load profile and set accurate state-of-charge readings for your printer's display.
RW420 printer goes silent mid-job — why the thermal head cuts out first
The RW420's thermal print head pulls a concentrated burst of current every time it fires a row of dots. When cell capacity degrades, voltage sags during that burst — even if the battery indicator still reads mid-charge. The printer interprets that voltage dip as a fault condition and halts the print job before the paper feed motor ever engages. Replacing the battery restores the headroom needed to sustain head-firing current without triggering that protective halt. A healthy cell under load should hold above 6.8V at the battery terminals during active printing.
Bluetooth drops mid-print job on the RW420
The RW420's Bluetooth radio and thermal head compete for current when a print job runs. At low battery charge, the voltage rail sags enough that the radio's power threshold is crossed — the connection drops, the job is cancelled, and the printer often shows no error code. This is not a pairing or firmware issue. Charge the battery to full, relaunch the print job, and confirm the battery voltage is at or above 7.2V at rest before starting large batch jobs.

Frequently Asked Questions
My RW420 printed fine yesterday but won't print anything today after sitting in the van overnight — what happened?
Overnight in a cold vehicle drops Li-ion cell voltage fast, and the RW420 requires a minimum voltage to drive the thermal head and paper feed motor together. If the resting voltage has dropped below the printer's motor-drive threshold, it powers on but produces nothing. Put the battery on charge for at least 30 minutes before retrying — if the printer then prints normally, the cell was simply too cold and discharged to engage the load. Check that resting voltage reads above 7.0V before the next deployment.
Print is coming out faded and patchy even though the battery shows full — is the thermal head worn out?
Not necessarily. The thermal head needs a stable, consistent voltage to hold the correct temperature across every dot row — if cell impedance has risen with age, voltage sags slightly during each firing burst even when the indicator reads full. That temperature variation shows up as uneven or faded lines on the receipt. Swap the battery and run five test prints; if density returns to normal, the head is fine and the old battery's internal resistance was the cause. A fresh cell should sustain above 7.2V under active print load.
Paper is jamming on every print job since the battery started getting old — could the battery actually cause that?
Yes. The paper feed motor relies on consistent torque, which drops when battery voltage sags under load. At reduced voltage, the motor doesn't apply enough pressure to pull the paper through cleanly, and the printer halts with a jam error even though nothing is physically stuck. Clear the jam, install a fully charged battery, and test the feed with a manual advance before loading stock. If the feed runs smoothly at full charge, voltage sag from the old battery was the cause.
