The NOCO GENIUS1 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 1-amp for lead-acid, gel, AGM, maintenance-free, and lithium-ion batteries.  That's pretty much all of the batteries...

Features:

• 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.
• Restore your battery - Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.
• The needle-nose style clamps are great for reaching terminals in tight spots, and they are removable, if you want to rock a pigtail whip.
