It is a current that flows primarily in one direction and then in the other. <ref name="Mueller1948">{{cite book|author=George Vernon Mueller|title=Introduction to Electrical Engineering|url=https://books.google.com/books?id=jCkhAAAAMAAJ|year=1948|publisher=McGraw-Hill Book Company}}</ref>

Complicated systems which have integrated recharging capability sometimes resort to using bidirectional currents, as in laptops or other systems. Monitoring of a bidirectional current is required for a laptop to report the battery level and charging status.<ref>{{cite web|url=http://www.maximintegrated.com/app-notes/index.mvp/id/1949|title = MaxIntegrated-Bidirectional Currents}}</ref> Components are available for this purpose.<ref>{{cite web|url=http://www.analog.com/media/en/technical-documentation/data-sheets/AD8218.pdf|title=www.analog.com/media/en/technical-documentation/data-sheets/AD8218.pdf}}</ref>
