2nd Battery

[tartuffe]

Question guys, I have a two-battery system with dissimilar batteries, one is a starter and the other a deep cycle. I keep them in parallel most of the time but when I am bottom fishing I switch to the deep cycle. I have sat for more than 5 hours without ever having an issue with multiple items drawing power.

Are you guys with duplicate batteries running deep cycle or starting? If starting batteries, how many hours of radio/stereo/live-well pump/occasional lights time are you getting out of a battery?

I ask because I am about to go with new batteries (been 4-5 years) and would like similar batteries but question if using deep cycle for starting works. Alternate is using starting batteries for long-draw applications.
