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 is a 7.4V 3400mAh lithium-ion battery for the Zebra RW220 and RW320 mobile receipt printers. It replaces OEM part numbers CT17497-1 and AK18026-002. Both printers share the same battery bay, connector layout, and BMS handshake protocol.
- RW220 and RW320 compatibility: Both models run the same 7.4V power rail and use an identical battery bay with the same locking tab geometry and BMS communication bus. One replacement covers both units.
- Bench tested on actual hardware: We ran this cell through the RW220 charge cycle and confirmed BMS handshake at 8.4V full charge. The protection circuit responded correctly to both undervoltage and thermal events during load testing across the paper feed motor and thermal print head.
- First-deployment print sequence: After installing, charge to full and run five continuous test receipts before field deployment. The thermal head draws peak current during warm-up, and this sequence lets the BMS log an accurate current profile for the new cell — preventing premature low-battery cutoff warnings during early shifts.
Why the RW220 cuts out during Bluetooth print jobs
The RW220 runs its Bluetooth radio and thermal head simultaneously during wireless print jobs. At low state of charge, voltage sag across both loads pulls the rail below the BMS floor, triggering a protection cutoff. This looks like a wireless disconnect but is actually a power event — the radio drops first because the thermal head is the higher-priority load. If mid-job disconnects increase as a battery ages, cell capacity has degraded past the point where simultaneous radio and motor draw can be sustained.
Faded or uneven print output on a freshly charged battery
The thermal print head in the RW220 depends on a stable voltage to reach and hold its operating temperature across the full print width. If the cell has degraded, internal resistance rises and voltage sags under thermal head load — the head underheats on some segments, producing faded or patchy output even when the charge indicator shows full. This is not a head fault or paper issue. Check open-circuit voltage with a multimeter: a healthy cell reads 8.3–8.4V at full charge. A reading below 7.8V at rest after a full charge cycle indicates cell degradation — replace the battery.

Frequently Asked Questions
My RW220 sat in a storage room for four months and now won't print — battery shows some charge but the printer does nothing
Extended storage allows lithium-ion cells to self-discharge below the minimum motor drive voltage, even when the indicator shows partial charge. The paper feed motor and thermal head both require the voltage rail to be above approximately 7.0V to initialise — below that, the printer powers on but will not execute a print job. Place the battery on charge for a full uninterrupted cycle before testing. If the printer still won't print after a confirmed full charge, the cell has discharged deep enough that BMS recovery is required — remove the battery, leave it out for 60 seconds to reset the protection circuit, then reinsert and charge again from zero.
The paper feed is jamming more often than it used to — I haven't changed paper stock or settings
Paper feed motor torque is directly linked to available voltage. As cell capacity fades, voltage sag under motor load reduces the torque the feed rollers can apply — paper that fed cleanly at full voltage begins to slip or stall at reduced drive current. This is not a mechanical fault with the rollers or a paper weight issue. Check whether jams happen more at the start of a shift (when battery is full) or later in the day. If jams cluster toward low battery, the cell is the cause — measure resting voltage after a full charge and replace if it reads below 7.9V.
The RW220 shows a full battery but starts throwing low-battery warnings after just a few receipts
This is a BMS calibration drift issue, common after a new cell is installed without running an initial conditioning cycle. The BMS uses historical charge and discharge data to estimate state of charge — on a new cell with no baseline, it can misread capacity and trigger early warnings. Run five to ten full print sequences back-to-back on a full charge without interrupting the cycle. If warnings persist after conditioning, measure the cell's open-circuit voltage immediately after a full charge — a healthy cell reads 8.3–8.4V, and anything under 8.1V at rest points to a faulty cell rather than a calibration issue.
