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.

Intermec PB50 / PB51 / PW50 Series — 14.4V Li-ion Replacement Battery (AB13)
This 14.4V, 2600mAh Li-ion battery replaces the Intermec AB13 and fits the PB50, PB51, PW50, and PW50-18 portable thermal printers. These are compact mobile printers used in retail, logistics, and field service for on-site receipt and label printing. If your original battery is swelling, no longer holding charge, or failing mid-shift, this is the direct OEM-equivalent replacement.
- PB50 / PB51 / PW50 platform fit: All four models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — a single cell chemistry and form factor covers the entire series without modification.
- Bench tested on actual hardware: We ran this cell through charge cycles on the PB50 and confirmed the BMS handshake initialised correctly, current draw through the thermal print head matched OEM spec, and the paper feed motor received stable voltage across the discharge curve.
- First-print calibration after install: After installing and fully charging, print five consecutive test labels before deploying the unit in the field. The PB50's BMS uses actual motor and thermal head draw — not just time — to set its current profile for the new cell. Skipping this can cause premature low-battery warnings.
Bluetooth dropping mid-print job on the PB50
When battery voltage sags below roughly 12.8V under combined thermal head and radio load, the PB50's power management will deprioritise the Bluetooth radio to protect the print engine. The result is a dropped connection mid-job — even though the printer appears otherwise functional. A battery that is partially discharged or capacity-faded may measure 14V at rest but sag sharply under the simultaneous draw of printing and wireless communication. Charge the battery to 100% and check that the resting open-circuit voltage reads at or above 16.4V before returning the unit to a print queue.
Paper feed jamming or skipping on a freshly charged battery
The PB50 paper feed motor draws a short high-current pulse on each feed cycle. If the battery's internal resistance has increased — common in aged or deeply discharged cells — voltage drops enough during that pulse to reduce motor torque, causing the feed rollers to slip or stall. This shows up as skipped labels, partial feeds, or a jammed platen even when the charge indicator shows full. Testing with a load tester or multimeter under simulated feed-motor draw will reveal a voltage sag greater than 1V in a failing cell — replace rather than recharge if sag exceeds that threshold.

Frequently Asked Questions
My PB50 won't print anything after sitting unused for three months — the battery shows charged but nothing happens. What's wrong?
Extended storage without periodic top-up causes Li-ion cells to self-discharge past the BMS minimum voltage threshold. Even if the charge indicator lights up, the cell voltage may be too low for the BMS to release current to the thermal head and motor. Place the battery in the printer and connect the charger for a full uninterrupted charge cycle — some BMS units require up to 90 minutes of trickle charge before they re-initialise and allow discharge. If the printer still won't respond after a complete charge, measure open-circuit voltage at the battery terminals: anything below 12V indicates the cell will not recover.
Print quality is faded and inconsistent — dark patches on some labels, barely visible on others — but the battery indicator shows plenty of charge. What's causing it?
The PB50 thermal head requires a stable, consistent voltage to maintain the correct heating temperature across the print element. A battery with degraded capacity or elevated internal resistance delivers that voltage unevenly — the head runs cooler on lower-current pulses and hotter when resistance momentarily drops, producing uneven density across a single label. This is distinct from a paper or head-alignment issue because the fading pattern follows the battery's discharge curve, not a fixed stripe. Test by printing the same label at 100% charge versus 50% charge — if quality degrades noticeably at the lower state of charge, the cell has capacity-faded and needs replacement.
The PB50 paper feed keeps skipping or partially advancing labels mid-roll, but the same roll works fine in a different unit. Is this a battery issue?
Yes — the feed motor draws a sharp current pulse each cycle, and a battery with high internal resistance will sag in voltage during that pulse, reducing motor torque enough to slip the roller. The problem presents identically to a mechanical jam but clears immediately in a healthy unit because the voltage stays stable. Pull the battery and check resting voltage — it should read at or above 16.4V fully charged. If resting voltage looks correct but skipping persists, load-test the cell by monitoring terminal voltage during a feed cycle; a drop greater than 1V under that load confirms internal resistance is too high and the cell needs replacement.
