Product Overview

The Genius 2 is a 2 Amp battery charger and maintainer. It's designed for all types of 6-Volt/12-Volt lead-acid batteries, including flooded, gel, AGM and other maintenance-free batteries. It features our all-new hyper-density technology making it the most compact, lightweight and energy efficient battery charger on the market, plus an integrated thermal sensor for improved battery life.
  • Meet the GENIUS2 - Similar to our G1100, just better. It's 57% smaller and delivers over 100% more power. And it's simpler and easier to use than ever before.
  • Do more with Genius - Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.
  • Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
  • Charge dead batteries - Charges dead batteries as low as 1-Volt. Or use the all-new Force Mode that allows you to take control and manually begin charging dead batteries down to zero volts.
  • Simple to set up and use - Plug-in, connect to the battery, select a charge mode, and start charging your battery. A fully-automatic, worry-free battery charger for year-round use.

    Super easy to use. It is not a fast charger, but it did bring two batteries back from the dead. Very good for the price point: https://m.youtube.com/watch?v=EvGaGa-Ccf0

    I have only been using The NOCO for about 3 weeks. It seems to be working good so far. I hope to remember to come back and write an update review later.
