Battery For Side Imaging Unit

Recommended Posts

I just recently purchased a Humminbird 798ci for my kayak and I was wondering what kind of battery and charger I can use. Since I do not have a trolling motor, there will not be any batteries already on board. I heard a small 12V battery will be enough, but how many hours will I be able to get out of this if I use side imaging? Also, what kind of charger do I need for this battery? Can I use my trolling motor deep cycle battery charger?

 

If anyone could recommend a type or brand of battery too, that would be really helpful.

The safest battery for kayak use is a sealed one. You can get those and a charger at Radio Shack.

A 7 AHr size would take care of the time you would spend on the water.

The power requirement for the 798 is about 3/4 A. 

 

If you want to use your high amp charger, then a ATV/motorcycle or lawnmower battery would be the best choice. Avoid spilling the acid though.

You need a 12v sealed lead acid battery.  I use a 12ah to run my 798 on my kayak.  I have a buddy who uses a 12v deer feeder battery to run his 798 and it doesn't last through a full day of fishing, I'm not sure what the ah is on his though.  

 

This is the charger I use.  I'm sure you could find one cheaper but this one works great.

You posted the wrong charger, that one is a 6V charger.

You are absolutely right, thanks for catching that.  I meant to grab the one next to it.  The link is fixed now.

Thanks for the responses so far. What is the right way to charge these batteries in order to prolong their lifespan? Do you guys charge them immediately after each use?
