Unitech PA768 Replacement Battery 3.85V 5100mAh

Up to 19% off
New arrival
From $116.99 USD $143.99
Shipping calculated at checkout.
Fits Unitech PA768 mobile computer, replacing OEM battery part 1400-900069G.
3.85V, 5100mAh Li-ion cell sustains continuous barcode scanning and wireless connectivity throughout warehouse and retail pick-and-pack shifts.
Slide-lock connector seats into the PA768 battery bay with the contact edge facing outward; locking tab clicks into the side slot.
We bench-tested this cell in a PA768 cradle and confirmed normal BMS voltage handshake on insertion; no fault codes or rejected charges.
Install the battery and place the scanner in its dock for a full charge cycle before field use—the scan trigger draws peak inrush current during rapid barcode bursts, and a pre-charged cell prevents nuisance BMS shutdowns on first shift.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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

🔹 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.

Unitech PA768 Rugged Mobile Computer — 3.85V Li-ion Replacement Battery (1400-900069G)

This 3.85V, 5100mAh Li-ion battery replaces part number 1400-900069G in the Unitech PA768 and PA768 Rugged Mobile Computer. The PA768 is a handheld barcode scanner used in warehouse, logistics, and retail pick-and-pack operations. Voltage and capacity match the original pack so the device BMS accepts the new cell without reconfiguration.

  • PA768 and PA768 Rugged compatibility: Both variants share the same 3.85V battery rail, identical connector pinout, and the same BMS communication protocol. One part number covers both — no adapter or firmware change needed.
  • Bench tested on actual hardware: We cycled this pack through full charge and discharge on the PA768 and monitored BMS handshake at startup. The protection circuit responded correctly to over-current and low-voltage cutoff thresholds on every cycle.
  • First-shift cradle charge: After installing, place the PA768 in its charging cradle for a full cycle before starting work. Scan trigger inrush current peaks when the cell is near minimum charge, and a fully charged pack prevents false BMS trips the first time the trigger is pulled in a heavy scan burst.

Why the PA768 drops its wireless connection during rapid scan bursts

The PA768 draws power from two simultaneous loads during active scanning — the imager and the wireless radio. A rapid scan burst pulls the combined inrush from both at once. If the cell voltage sags below the radio module's minimum operating threshold mid-burst, the radio drops out before the scanner does. A fresh, fully charged cell holds voltage under that combined load where a degraded cell cannot.

Cradle showing a charging error after fitting the new pack

A charging error on the cradle dock immediately after a battery swap almost always traces to contact resistance, not a faulty cell. The dock contacts on the PA768 cradle and the battery pack's gold contacts both collect oxidation and debris during warehouse use. Wipe the contacts on both the pack and the cradle with a dry lint-free cloth, then reseat the scanner firmly until it clicks. If the error clears, the pack was not at fault — the dock contacts were the gap. Target a dock contact resistance below 0.1 ohm for stable charge initiation.

Frequently Asked Questions

My PA768 stops reading barcodes partway through a shift even though the battery indicator still shows charge — what's happening?

The imager requires a minimum sustained voltage to fire reliably, and a degraded or partially charged cell can drop below that threshold under load even while the on-screen indicator still reads mid-charge. The indicator reads resting voltage, not load voltage — those two numbers diverge as the cell ages. With this replacement pack at full charge, the cell holds voltage through sustained scan bursts without that mid-shift sag. Charge the new pack fully in the cradle before the first shift and retest on the same scan-heavy task.

The PA768 feels noticeably warm after a long warehouse shift — is something wrong with the battery?

Heat during an extended shift is normal for the PA768 because the housing is sealed for rugged use, and there is little airflow to dissipate the combined thermal output of the imager, wireless radio, and battery discharge. A worn cell running at a higher internal resistance generates more heat than a new one under the same load. If the unit is too hot to hold comfortably, that points to elevated internal resistance — check that the replacement pack contacts are clean and fully seated, and note whether the heat reduces with the new pack. Internal resistance on a healthy Li-ion cell at this capacity should stay well under 100 mΩ.

The scanner powers on after the swap but the battery drains faster than expected across the shift — what should we check first?

Short shift endurance on the PA768 is almost always driven by two compounding loads: scan burst frequency and wireless polling interval. If the unit is configured for aggressive wireless polling — common in real-time WMS environments — the radio draws continuous background current on top of every scan trigger event. Confirm the new pack completed a full cradle charge cycle before use, since a pack pulled from storage at 40% capacity will underperform from the first shift. If endurance is still short after a full charge cycle, check the wireless polling interval in the PA768 device settings and reduce it where the WMS workflow allows.
