Power Supply
Replacing the rechargeable battery
Replace the battery when the P-touch can only be used for a short time even after 
recharging. The battery may not be charged sufficiently when the power supply is less 
than the rated voltage. While the replacement period varies depending on the 
conditions of use, the battery will generally need to be replaced after approximately one 
year. Be sure to replace it with the specified rechargeable battery (BA-18R).
Press on the back cover opening grip and open the back cover.
Slide the battery case cover in the direction of the arrow and open the case.
Remove the expired battery and disconnect the 
connector.
Connect the connector on the battery wires and insert the new battery into the 
case. Refer to “Installing the rechargeable battery” on page 16.
Attach the battery case cover and close the back cover.
• Be sure to charge the battery before using the P-touch.
• Connect the AC adapter directly to the P-touch to use it when the battery’s charge becomes 
low.
• Return the P-touch to the battery charger after use. Even when not used the battery will run
down if the P-touch is not placed on the battery charger.
• Leaving the P-touch on the charger even when the battery is fully charged will not damage it.
• The battery may not be charged sufficiently when the power supply is less than the rated 
voltage.
• Even if there is no rechargeable battery inserted in the P-touch, the charging indicator may
remain lit for approximately 10 minutes when set in the battery charger with the AC adapter 
connected.
Be sure to charge the new battery for 2 hours after replacement.
