Frequently Asked Questions
How long does the GENIUS5 take to charge a 12V battery?
A: It depends on the battery's size and how depleted it is. A typical car battery at around 50% charge usually takes 4 to 8 hours to fully charge at 5 amps, while a larger or more deeply discharged battery can take a day or more.
Can the GENIUS5 charge a completely dead battery?
A: Yes. It can detect and begin charging batteries as low as 1 volt, and its Force Mode lets you manually start charging batteries that have dropped all the way to 0 volts.
Is the GENIUS5 compatible with my vehicle's battery?
A: It works with 6-volt and 12-volt lead-acid batteries (flooded, gel, AGM, and EFB) as well as 12-volt lithium batteries found in most cars, SUVs, trucks, and luxury vehicles. Just select the charge mode that matches your battery type before starting.
What's the difference between the GENIUS5, GENIUS2, and GENIUS10?
A: The amp rating tells you the charge speed and battery size each is built for. The GENIUS2 charges at 2 amps for batteries up to 40Ah, the GENIUS5 charges at 5 amps for batteries up to 120Ah, and the GENIUS10 charges at 10 amps for larger batteries up to 230Ah.
Can I leave the GENIUS5 connected to my battery long-term?
A: Yes. It's built to stay connected 24/7, automatically switching to a low-current maintenance mode once your battery is fully charged.
