How long does the battery last on a full charge?

On a full charge, the DEV printer battery can last for several hours of continuous printing or can print hundreds of receipts or labels, depending on how the printer is being used. Actual battery backup may vary based on factors such as:

Print density
Print speed
Bluetooth usage

The printer is equipped with a 2000 mAh rechargeable battery, which is designed to support portable business usage throughout normal printing sessions. Heavier usage, darker printing, faster print settings, or long Bluetooth-connected sessions may reduce backup time compared to light use.

Battery Performance Depends On
