Direct replacement for Brother label printers

The Estry PT-18RZ is an 8.4 V 700 mAh nickel-metal-hydride pack built to match the original Brother BA-18R and BBP-18 cells. It fits the PT-18RZ, PT18R, PT18RKT and PT-18R handheld label makers without modification. Safety circuits guard against over-charge, over-discharge, over-voltage and short circuits.

Upgrade from depleted or aging original cells

When the factory pack no longer holds a full day of label printing, this 5.88 Wh replacement restores the original run time. The jump is worth it if the printer shuts down mid-job or the charge indicator drops quickly after a fresh charge. It does not add capacity beyond the 700 mAh rating, so users needing longer shifts must carry a spare pack.

Limited to devices that accept the 89.08 × 21.4 ×

The pack only works in Brother models that list BA-18R, BBP-18 or LN6044001 as the approved part number. It cannot be used in printers requiring a different voltage, connector layout or physical envelope. Certifications include ISO 9001, RoHS, CE, UN 38.3 and MSDS for transport compliance.

Questions about this item

Will the 89.08 × 21.4 × 21.4 mm pack fit my Brother label printer?

The pack matches the original 89.08 × 21.4 × 21.4 mm size, so it slides into the same battery compartment used by the PT-18RZ, PT18R, PT18RKT and PT-18R models.

How do I install the 8.4 V 700 mAh Ni-MH pack without damaging the connector?

Align the polarity-marked plug with the printer socket, press straight in until it clicks, then charge fully before first use; forcing the connector at an angle is the step most users get wrong.

What replacement will the 5.88 Wh Ni-MH pack need after its service life?

After the 1-year battery-pack period, replace it with another 8.4 V 700 mAh Ni-MH pack carrying the BA-18R, BBP-18 or LN6044001 part number.
