Brother BA-7000 P-touch Label Printer Replacement Battery 8.4V 700mAh

Up to 20% off
New arrival
From $28.99 USD $35.99
Shipping calculated at checkout.
Fits Brother P-touch PT-7600 and P-Touch 7600VP label printers using OEM part BA-7000.
8.4V at 700mAh capacity delivers stable voltage across thermal print head and paper feed motor throughout charge cycle.
Connector slides vertically into printer bay with locking tab on left side; orientation marked on pack underside.
We bench-tested this cell on a PT-7600 charger — BMS accepted the pack on first insertion with no fault codes or cutoff events during discharge cycle.
After installing, charge fully and print five test labels before deployment — the paper feed motor requires initial calibration cycles to confirm voltage stability under load.

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.

Brother P-touch PT-7600 — 8.4V Ni-MH Replacement Battery (BA-7000)

This is an 8.4V 700mAh Ni-MH replacement for the Brother BA-7000 battery pack. It fits the P-touch PT-7600 and PT-7600VP handheld label printers. The pack slots directly into the battery compartment and connects to the onboard charge circuit without modification.

  • PT-7600 and 7600VP compatibility: Both models run from the same 8.4V rail and use the same BA-7000 footprint. The charge management circuit expects Ni-MH chemistry — this pack satisfies that handshake so the charge indicator behaves normally.
  • Bench tested on actual hardware: We cycled this pack through charge and discharge on a PT-7600 unit. The BMS accepted the cell without throwing a fault, and the thermal head voltage held stable across a full label run.
  • First-use print sequence for PT-7600: After installing, charge the pack fully, then print at least five test labels before field use. The PT-7600 feed motor draws a short high-current burst on each cut cycle — running that sequence lets the BMS log the current profile for the new cell and prevents false low-battery flags during normal jobs.

Thermal head voltage drop on the PT-7600 mid-label run

The PT-7600 thermal head needs a steady voltage to maintain consistent heat across the full label width. When cell capacity has degraded, voltage sags during the print cycle and the head temperature drops unevenly. The result is faded patches or lighter characters toward the end of longer labels. A fresh 8.4V pack eliminates the sag — confirm the charge indicator shows full before running a test print.

PT-7600 shows low battery immediately after a long storage period

Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. A pack left unused for several months can drop below the printer's minimum operating threshold — around 6.5V — before you even start a job. At that voltage the PT-7600 refuses to print and flags a battery error. Put the pack on charge for a full cycle before concluding it is faulty; most packs recover to normal capacity once voltage is restored above 7.2V.

Frequently Asked Questions

My PT-7600 prints the first label fine but every label after that comes out faded — is the battery causing this?

Yes. The thermal head on the PT-7600 draws repeated current bursts across a label run, and a weak or partially charged Ni-MH pack can't sustain the voltage needed to keep head temperature consistent. Each successive label gets slightly less heat, so print density drops off. Charge the battery to full and retest — if fading stops, the cell was the cause.

The PT-7600 paper feed is jamming even though the cutter motor sounds like it's running — what's happening?

The feed motor and cutter motor on the PT-7600 share the same battery rail. When voltage drops under load, the feed motor loses torque before the cutter motor audibly stalls — so you hear the cutter but the media doesn't advance cleanly. This is a voltage-under-load symptom, not a mechanical jam. Charge the pack fully and check that the battery voltage reads at least 7.8V under the load of a test print before assuming a paper path fault.

After sitting in a drawer all winter, the PT-7600 powers on but won't start a print job — it just shows a battery warning instantly.

Ni-MH packs self-discharge over months of storage and can fall below the PT-7600's minimum drive threshold, which sits around 6.5V. At that level the printer powers the display but blocks the print cycle to protect the thermal head circuit. Connect the charger and leave it for a full uninterrupted charge cycle — if the pack responds and climbs above 7.2V, it will recover. If the charge indicator never advances past the first bar after 90 minutes, the cell has lost the ability to hold charge and needs replacing.
