The NOCO GENIUS2 is a 2-amp charger, maintainer and desulfator for 6-volt and 12-volt lead-acid batteries (flooded, gel, AGM and maintenance-free) plus lithium-ion batteries. It can detect and charge batteries as low as 1 volt, a manual Force Mode handles batteries below that, an integrated thermal sensor adjusts the charge cycle to ambient temperature, and the whole process runs automatically; NOCO says it is about a third smaller than the older G1100.
