Trojan's are awesome.  I've heard nothing but the best about them and I have used them and had great luck.

Trojan's are an excellent choice. 

2 other brands worth checking out are MinnKota and DieHard.  I know, sounds odd (especially the DieHard), but when you compare specs side-by-side with the Trojans, they're pretty much the same. 

My MinnKota batteries have been outstanding, and the Ranger dealer (Dan) swears by them.  And I used DieHards in the tin boat with no complaints.

If you've done all your shopping already, and have narrowed it down to the Trojans and Optimas, get the Trojans.

O.K.........now I am confused......when I saw the title..."Deep Cycle TROLL Batteries" I thought I had a handle on the question but alas....I again missread things. It was not until I ventured to Ballard and attempted to discuss the situation with the TROLL under the bridge. One thing I had forgotten about was that there are certain others under the bridge who were not as freindly and after several rounds of beatings and pummellings I realized that maybe indeed the TROLLS were in need of new batteries themselves as they bothered not to come to my aid....I gathered my strength and made my way to the back of the TROLLS where I had assumed the DEEP CYCLE BATTERIES might be inserted and again I met with Uncle Pain as a local Police Officer began firing his Tazer into my back yelling "Pervert! get away from the backside of the TROLL".
So.......several things were learned about DEEP CYCLE TROLL BATTERIES......
1).....Seattle Police Tazers have a long discharge range with lots of extra power but are no good for fishing.
2).....Always pack extra beer in the trunk for Anti-whoopin insurance when fishing around bridges and peirs.
3)....TROLLS do not exist and if they did would not require BATTERIES!
4)....Most of all LISTEN MORE CLOSELY!!

              

See ya on the water!

my 2 cents;
I have trojans in the Skeeter and haven't had much proble with them just learned that you can't trust an cheap auto charger. and boiled them dry. But I topped them off and recharged them. haven't been a problem since.

Like Steve H. stated, I've used Delco's for years without a problem, and gotten an average 4 years of life out of a set.   My new Stratos came with Trojan SC 200's and while they are new, they do seem to work well.  Time will tell.  
The problem with Delco batteries is trying to find them at a retail outlet for a reasonable price since K-Mart quit handeling them . ???  Atomic batteries at the intersection of Grady Way & Rainier Ave in Renton used to offer some darn good deals on blems in both Delco & Trojan.  You might check them out.

Reading Larry's posts is better than "Laughter, the Best Medicine" in the Reader's Digest.  Cheered me up while I am home recuperating this week.  Keep up the good posts, Larry!
