vexilar battery for my fish finder?

[blaserbaby]

Has anyone ever used a vexilar battery to power their fish locator? I have a humminbird 386ci. Ive been running my locator and 36# thrust trolling motor on the same size24 deep cycle battery havent ever drained it yet. Any help would be appreciated!

Here's chart to show current draw of Humminbird units. One can figure approx. battery life, knowing amp hr of battery you have and current that your depth finder draws.
