What’s a good stereo battery?

[luke22885]

I have a 2005 21v and need to replace the second battery for the stereo. Any suggestions on a good one? Had 2 regular die hard deep cycle batteries the last few years but just the cheap ones. I read some good things about interstate marine and have a dealer close by, those good?

Thanks in advance

Ive been using interstate marine for years, with good results. If space permits, go with a group-29.
