Description
A battery tester and charger are used to assess the health and charge level of a battery, allowing you to identify if a battery needs to be replaced or recharged. They can be used in various applications like checking car batteries, powering small electronics, or maintaining backup power sources, essentially providing a way to monitor and manage battery performance by measuring voltage and delivering necessary charge when needed; a tester can also help diagnose issues like faulty cells or alternator problems in a vehicle charging system.
