I also run the Blue Top D31 Optima's and I can't say enough good things about them. Yes they are costly but look on the internet. I got free shipping on mine. I keep a trickle charger on both and I have no issues.

i run an optima 34 in my nitro , 12 volt , fish every weekend and have had zero problems with it . i was going through an interstate battery every year . bought mine at sams club , just under 200 dollars . more expensive than the other batteries but saved me money in the long run.
