This Turbo Charger-Analyzer from Powerex is an eight-bay charger with separate charging circuits. You can charge AA or AAA NiMH batteries independently or at the same time. Inserting the batteries automatically sets the charger into a default charging mode, charging the cells within two hours, but it can also be set to a Turbo Mode which will charge the batteries within one hour. With a touch of the button, the charger analyzes the battery health and accurately displays capacity on the large backlit LCD display. During the charging process the Thermal Management System prevents the batteries from overheating. If you have older batteries, they can be revived with the charger's Deep Battery Conditioning System.
