My two sets of criteria were: total cost of ownership over 4 years and ease of exchange. Most of the AGM batteries I researched came with a 2/3 year warranty and wet cells were 1/2 year warranty so over a 4 year period I figured I had to buy 4-6 batteries total. I approximated 4 AGM batteries at $250 x 4 = $1000 and 6 standard wet cell batteries at $70.00 x 6 = $420
I opted for two of the $70.00 Walmart Everstart MAXX-29 batteries which have 125 Amp Hour rating, 875 MCA (Marine Cranking Amps), 205 minute reserve, and 12 month full replacement/24 month prorated. Similiar batteries at Costco and/or Sams Club if you have one of those whole sale cards. Plenty of Walmarts in the US for easy battery swap. Most of the guys on the fishing forum say they are getting 18-36 months out of the Deep Cycle MAXX-29 batteries. This is my first season with these batteries so only time will tell but for at least 12 months, I get full replacement if one goes bad. Even if my Walmart batteries did go bad, I could buy 12 Walmart batteries and it would still be cheaper than buying 4 AGM batteries.
I had 3 Kinetik batteries in my old 2006 Supra 21v. They worked well for the two years I had the boat. I did put them on a trickle charger once a week to keep them maintained because I was paranoid about them after spending so much money to purchase them. I told myself, I was never spending that much money on batteries again!!!
Just my 2 cents!
