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 RW220 / RW320 — 7.4V Li-ion Replacement Battery (CT17497-1)
This 7.4V, 2600mAh Li-ion battery replaces the CT17497-1 (also listed as AK18026-002) in the Zebra RW220 and RW320 mobile printers. These are portable receipt and label printers used in retail, logistics, and field service. Voltage and capacity match the OEM specification exactly.
- RW220 and RW320 compatibility: Both models share the same 7.4V battery platform, connector pinout, and BMS handshake protocol. One battery covers both units with no adapter or modification needed.
- Bench tested on actual hardware: We ran this battery through a full charge cycle on a RW220 unit and confirmed the BMS current profile accepted the new cells without error flags. The thermal print head and paper feed motor both drew stable current across the voltage range.
- First-deployment print sequence: After installing, charge fully and print five test receipts before deploying in the field. The paper feed motor and thermal head together draw a specific current profile on startup — running this sequence confirms the BMS has correctly mapped load behaviour for the new cell.
Why the RW220 refuses to print after sitting unused for weeks
Mobile printers like the RW220 draw a combined load from the thermal head, paper feed motor, and radio simultaneously. If the battery sits discharged for an extended period, cell voltage can drop below the BMS's minimum drive threshold — typically around 6.0V for this platform. The printer powers on but will not initiate a print job because the BMS blocks output to protect the cells. A slow pre-charge from a wall adapter for 20–30 minutes before a full cycle usually recovers the battery and clears this lockout.
Faded or uneven print output on an otherwise working unit
The RW220's thermal head regulates print darkness by holding a precise temperature across the print bar. When battery voltage sags — common in aged or partially discharged cells — the head temperature drops mid-print, producing faded bands or inconsistent density. This is not a head fault or paper issue. Check battery voltage under load: if it reads below 7.0V during a print job, the cell is the cause. Replacing the battery and running a full charge cycle resolves the thermal instability.

Frequently Asked Questions
My RW220 powers on but won't start a print job after the unit sat in a van for two weeks — what's wrong?
Extended storage while discharged drops cell voltage below the BMS minimum motor-drive threshold, which blocks print output even though the printer appears on. Connect the unit to a wall charger and let it pre-charge for 20–30 minutes before attempting a full charge cycle. Once cell voltage recovers above approximately 6.8V, the BMS releases the output block and normal print jobs resume. If the battery won't hold above 7.0V after a full charge, the cell has degraded and needs replacement.
Print jobs are coming out faded in patches — the paper and head are fine, so what's causing it?
Patchy or faded print is a voltage stability issue, not a hardware fault. The thermal head needs a steady voltage to maintain consistent temperature across the print bar — when the cell sags under load, the head cools mid-print and output density drops in bands. Check battery voltage during an active print job: a reading below 7.0V under load confirms the cell is the cause. Fitting a fresh 2600mAh cell and running a full charge cycle before deployment resolves the temperature variation.
The RW220 keeps dropping its Bluetooth connection mid-job — is this a battery issue?
Yes, this is a voltage sag problem. The Bluetooth radio draws additional current on top of the thermal head and motor load — when the battery is weak or low, combined current demand causes voltage to dip below the radio's operating floor, and the connection drops. It typically happens mid-job rather than at startup because load accumulates as the print cycle runs. Charge the battery fully and retest; if drops continue at charge levels above 50%, the cell has lost enough capacity that it can no longer sustain the combined load and should be replaced.
