NOCO GENIUS-GEN2 user manual

Yes, NOCO Genius is designed to charge dead batteries. It has a feature called "Force Mode" or "Force Charge" that allows it to charge batteries that are severely discharged or completely dead.

The Noco Genius 2 is a 2-amp battery charger, which means it charges at a slower rate compared to higher-amp chargers. The charging time for a car battery depends on several factors, including the state of charge of the battery and its capacity.
On average, for a battery with a capacity of around 50-60 Ah (amp-hours), it would take approximately 5-10 hours to fully charge the battery with the Noco Genius 2. However, if the battery is severely discharged or larger in capacity, it may take longer.
It's important to note that the Noco Genius 2 is designed to provide a slow and safe charge, which helps extend battery life. If you need a faster charging option, you may consider a higher-amp charger from the Noco Genius lineup or other brands. Additionally, always follow the recommended charging guidelines and safety instructions provided by the manufacturer.
