[Latest update from AliveCor Official Site] FDA guidance now allows the emergency use of KardiaMobile 6L to measure QT duration in patients being treated for COVID-19.

Does KardiaMobile need charging? How long will the battery last?

The KardiaMobile EKG hardware does not need to be charged. The internal battery in the monitor will last 1-2 years of normal use (2-3 recordings a day). The battery may prematurely drain if a connection is continually made with both electrodes to skin or metal.
