NOCO GENIUS1 1A 6V/12V Smart Battery Charger and Maintainer

Brand:
NOCO
Part no:
GENIUS1

The NOCO GENIUS1 (part number GENIUS1) is a 1 amp smart charger and maintainer for 6-volt and 12-volt batteries. It is sold for daily battery maintenance or long-term storage of boats, among other vehicles, and it takes 100-240 V AC input with a 15 watt output. It is rated for batteries up to 30 Ah. It lists support for lead-acid automotive, marine and deep-cycle batteries, including flooded, gel, AGM and maintenance-free types, and also lithium-ion. An integrated thermal sensor detects ambient temperature and compensates charging for hot and cold conditions. Spark-proof connections and reverse polarity protection are built in, and it carries a 3-year warranty.

Our take

This suits a small 6 V or 12 V boat battery, up to about 30 Ah, that needs topping up over winter or through storage. Skip it for large battery banks or quick recharging, since 1 A is slow. It has no stated waterproof or IP rating, so keep it out of wet, exposed spaces.
