Fish finder/battery question

[jhoss]

Here's the one I got recently. I was having problems after purchasing the elite 5 chirp when using my 12v 7ah battery.

This one is a 12 ah, and I have yet to run out of juice- even on all day an 1/2 the night excursions

I use an old fios battery from the box after I cancelled my service with them. Works great.
