Using this with my helix 5 and haven’t been under 100 percent charge. I’ve used it for out to five hours a trip and charge stays 100 percent. I charge after each use. Great product and very light weight.

This lets me ice fish all day long with my Humminbird Helix 5, and the unit never displays less than 100 percent battery power. But the real surprise was the weight–it feels like there’s no battery in the unit which makes it so much easier to hole-hop.

I love this battery. I initially purchased a 65$ lithium battery from a different company. It was the worst. First one wouldn’t charge and the second replacement did the same. I returned it and purchased a Dakota. I had to wait for 2 weeks but it was worth it. Much lighter than Lead acid battery and lasts all day fishing. I started fishing at 7am and by 1030 the battery still read 100% charged. My Dakota battery was worth the money.

Works great powering my family room desk lamp with 7w 12vdc light bulb.

So far it holds chrge alot longer than regular battery. It is great.

I bought this battery to replace the junk battery you get from Hummingbird with the Helix ice 7. The original battery would last about 6 hours in night mode and the screen brightness turned down too. With the Dakota 10Ah battery I have fished 9 hours with the same setting and the battery display is at 97% left. I am super impressed with this batteries run time and weight. I would recommend picking one up if you are having any problems with your lead cell batteries run time.

Incredible battery! Almost tripled the run time of my Ice Helix 7 compared to the factory SLA battery. Worth every penny!

Simply awesome. Will definitely purchase another one for more gear I have.

Great so far.powers my helix 7 with no problem for a whole day with no draw down
