Battery packs last approximately 1,000 to 3,000 charging
cycles before they need to be replaced. This is impacted by
applications and environmental factors.
The Allegro 3 is designed to run in either of two power states,
battery power, or external power with battery installed.
The unit is not designed to run on external power without a
battery. Doing so can damage internal components of your
unit and void the warranty.
