Lawnmower battery for sonar?

Recommended Posts

Has anyone tried using a lawnmower battery  to run a sonar unit? What kind of life can I expect?  How about putting 8 D-cell batteries together, What kind of life can I expect out of a set of batteries.

I am using a Eagle Fishmark 320 and I only have 1 battery for the TM and sonar.  I am trying to clear up a little interference issue I am having.

Eagle sells that same unit in a portable model that runs on "D" cells.

I would recommend getting a small gel cell battery and charger so you do not have to worry about acid spills. I would think using "D" cells would empty your wallet pretty quick.

this battery should keep you on the water all day.

this charger should keep your battery topped off when your not using it.

A little more compact is the 12 volt batterys for emergency lighting or pick up a battery for Acu View about $25 at BPS same thing. Then get a power point with clips to charge.

Using D's will cost.

Some kayakers use 12V deer feeder batteries to run their fishfinders.  You can find them for less than $20 on the web.

I have a cheap locator on the pontoon and put a motorcycle battery to it.  Have the battery strapped down in the steering console storage.  Works fine.

I use a lawn tractor battery as a cranking battery for my 20 hp outboard. My livewell pump also runs off this battery. It was worked well for me, I just make sure to charge it fully after a few long days of use.
