Which Battery is best?

[bigeasy1]

I've used Interstate batteries for more than twenty years with no problems.Currently,on my Tsunami,I'm running two batteries,one is a grp 24 marine cranking battery and the other is a grp 27 deep cycle.These are in conjunction with a perko switch.

God, I'm terrible with my batteries,I rarely check them,and I keep saying that I'll switch back and forth from day to day,or that I'll always run the deep cycle when I'm trolling with the elec.downriggers,vhf.radar, etc all on.The truth of the matter is I forget,so god only knows how many hours are on each one.
Been 6 years now,they still test good,but maybe one of these days it's going to be time for a couple new ones.
I think I'll have to put a big sticker next to the ignition switch that reads,

" HEY! STUPID, CHECK THE BATTERIES"
