HULKMAN Sigma 1 Car Battery Charger, 1A 6V/12V Automatic Smart Trickle Charger, Battery Maintainer, and Desulfator with Intelligent Interface

Received battery charger. Tested it and it works as advertised. Good value for a product received. Comes with ring, connectors, and battery clips. The connector for these is not standard, but does look to be well-built. Will not be used until winter storage of lawnmower. Will be 5 stars if it passes the test of time.

It's much better solution, súper pass my expectations!! Incredible quality. 200% recommended warranty!!!

charges everything from my riding mower 12v battery to my toddlers ride on toy 6v battery. good quality gator clips.

Great price. Already gave one as a gift. A great fail safe to keep in your car especially if you have an older battery.

trickle chargers perfect for keeping batteries alive during winter months

Good little charger, simple to use.

Bought to replace another brand that went dead. Seems to be an excellent charger maintainer with great charging options. As always the Hulkman products are great quality. Very nice products. I have two of the 85s jump starters and they are very powerful. I live in MN and the Hulkmans are the only ones rated for such cold temps. I jump started a completely dead battery with no dash lights like nothing even in the cold. Thanks Hulkman.

Awesome product, works great.

Operation on screen is bit confusing

I charged this by plugging in before I put it out. the only time its been on was from that charge.
