Battery answers..........
« on: Jan 15, 2010, 10:39 PM »
Dear List;
I am electrically charged with energy!

For the last three seasons I have been operating my hummingbird fish finder with the disposable 12 volt batteries one gets at a hardware store. Around $12 and they last for about six trips out.  Voltage falls down from 11.6 to just above 7 and the finder dies.

I bought a new rechargeable yesterday and the voltage started at 12.7 and stayed there after six hours of use. The fish finder could be seen working better with the consistent voltage.  I am headed out again fishing tomorrow and brought the battery indoors to keep it warm over night and will charge it up tomorrow night to see how it functions after a second day's usage.  Just thinking, I have the trickle charger,and a power converter for my pickup.   I can charge it to and from fishing with two hours in the truck on the road!

TIP:  if you are using the throw away batteries, for $22 you can get one to charge, and your fish finder will love you for it. 

The light bulb came on today.  Some things take a little time to figure out. :thumbsup:

Go to your local Ace Hardware store, look in the battery section.   Down on the bottom shelf is the large lantern (the big electrical battery powered "flashlight" for camping use), those are 6 and 12 volt disposable batteries.  They will run a light, or a radio, or a fish finder.

I guess I've never looked hard enough...I've seen them as 6 volt batteries only.  Didn't know they were 12 volt type as well.

They run about $12 and do last a half dozen trips to the ice.  The newer sort of motor cycle batteries last 10X longer and charge right up.
A much better way to go. Size is about 2.5 X 3 X 5 inches, weight is about 4 pound. fits with the finder in a med. sized black pastic tackle box from Home Depot for $6.
