Humminbird 770030-1 9AH BK 9 Amp Hour Battery Kit, Portable Configuration, Black, Small

used with portable helix 5 on trip to Ontario and lasted all day on the water, over 10 hours.

Had battery and charger together, best price. Should add ends to the wires to slip on battery terminals on charger.

Works like it should. Connectors like battery post would be nice.

obviously with covid and being outdoors more, i got into kayak fishing pretty heavily, this included needing a power source for my helix 7 fish finder. when you are out on the lake all day you need a battery that will last you a long time making sure you track your movements and mark POI's. overall this battery will last me between 8-10 hours of use with just my fishfinder, i have it wired so that i can also plug in my phone and charge it off of this at the same time. and this will reduce the overall use to about 6-8 hours. overall a great battery and easy to charge and hook up.

Holds a great charge for a long time in all temperatures. Goes great with the Humminbird fish finder.

Battery worked perfect and lasted. Ice fishing here in Michigan, this is exactly what I needed.

I am so glad I could find these. We love the hummingbird and needed an extra battery Thank You
