Smaller and more powerful than its predecessor, Noco’s Genius1 will keep your batteries in top shape. Compatible with 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, it has an integrated thermal sensor to prevent over-charging in hot climates and under-charging in cold climates. It can also charge completely dead batteries, automatically detect and reverse sulfation/acid stratification to increase the performance and lifespan of older batteries, and has redesigned clamps that make it even easier to use.
