What is the difference between the 12.8V Duo versus the regular one?

The 12.8 V Dou is suitable for lithium-ion batteries as well as lead acid batteries.

What is the difference between all the chargers optimate offers? i want to charge an agm battery, prius 2001 car. thanks.

The one I have is a maintenance charger it charges and maintains battery health and longlife

The company which is Tecmate was founded in Belgium in 1994. They manufacture chargers for many brand names, however I'm not sure where they are actually made!

Will this charge a dead 12v auto battery? Or is it used just to maintain a battery?

*Perfect for charge and maintenance of all 12V lead-acid (STD, AGM, GEL) and 12V LiFePO4 'Lithium'.
