I've had the best performance and not babying by using AGM batteries.
I don't know the brand (but I bet they came from Advance or TSC) of my batteries but I noticed the sticker on it was 03/11 when I put the charger on the starting battery. I used to have a lot of trouble with batteries until I starting cleaning my connections twice a year, in spring before fishing season and in fall before hunting season, and I started putting the batteries on a charger after everytime I used them to keep them fully charged.
I have never messed with putting water in these, I just make sure they stay charged after use.
I have my starting battery and accessory battery wired in parallel. The motor is wired directly to the starting battery. All accessories save for the trolling motor are going through Johnny Ray battery terminals on the accessory battery.
I want to say there are only a very few (lead acid) battery manufacturers in the US. Most of the different brands are made in the same factory I guess. I wish I had the coin for a lithium set up mainly for weight savings. My batteries are in the bilge area and it would be nice to have less weight back there.
Has anyone used the auto zone. Duralast lately? Group 29
840 cranking amps and 210 reserve capacity.
It sounds good to me from what I’ve read on here.
I’ve been using the Walmart batteries but as someone said they don’t show the reserve capacity anymore so scared me off. The auto zone is on sale for 99$. Did not check on the garentee

i have a everstart battery from wallyworld the last time i used it i noticed i bought it in 2011. i bought a small deep cycle battery from academy sports can't remember the brand and bought it because a lot lighter than the everstart but it only lasted a few year.
I have been fishing Cabelas AGM batteries for the past ~10 years. The first set lasted 6 years so I was very happy (300 to 400 charging cycles). The second set started failing after 3 years, which is disappointing (less than 200 charging cycles). They were all made in china, but evidently the purity of the lead is not as good in the newer ones so the batteries have a shorter life. Many brands now offer a "high purity lead" version of their AGM batteries for about double the price, but the warranty is only 2 to 3 years, so you probably won't get double the life for double the price.
I have been researching batteries and it seems for AGM it's tough to beat Interstate Batteries, but it's really hard to find the deep cycle AGM Interstate batteries in stock anywhere. Costco doesn't carry the deep cycle AGMs unfortunately. Did some research on the GEL batteries and found out the manufacturers rarely honor the warranty when they fail prematurely; since they are as expensive as the "high purity lead" AGM batteries they are not worth the risk in my mind.
The next generation super long life deep cycle batteries are Lithium Iron Phosphate (LiFePO4). They have a lifetime of 3500 to 7000 charge/discharge cycles (AGMs are ~300 cycles typically), and they weigh less than half as much as a lead-acid or AGM battery. The price however will make your hair stand straight up! (for those of us that still have hair). If you have a modern on-board charger it is probably compatible with Lithium Iron Phosphate batteries in "AGM mode", so that's good news (double check your charger before you buy!).
Every year for National Battery Day ReLiON (relionbattery.com) has a 15% discount on their Lithium Iron Phosphate batteries (this year that discount runs from Feb 17 to Feb 21), so I decided to take the (very expensive) plunge and order 1 for my boat (to replace an AGM battery with weak cells). It weighs 1/3 of the weight of the AGM battery it is replacing (same physical size). I will post a review after I have it for a while and let you know if I feel I am getting my money's worth. I have a bunch of electronics on my boat, including livescope, so there is a pretty big load on this battery. If all goes well I will replace my trolling motor batteries with Lithium Iron Phosphate when the time comes....
Note that is you want to use a Lithium Iron Phosphate battery as a starting battery (as well as for electronics) that the standard Lithium Iron Phosphate battery will not work as a starting battery - you need a special "high power" version capable of higher surge currents when the starter is engaged. (These are smart batteries with an internal battery controller that will disconnect if there is excessive current draw.)
I have no relationship with ReLion or any battery manufacturer, this post is just my opinion.... Tight Lines everyone.
I had a place recomend Odyssey Extreme batteries

I agree with lithium ion ohosphate being the next big thing in batteries. What i don't understand is why are two batteries rated the same npt pretty much the same weight? I've been looking at deep cycle 12 volts to power my livescope with when i get it insdtalled & batterys on 12 volt 30 amp may weigh 4 lbs. & the next one may weight 9 lbs. What is the reason fror it? Unless of course some that are being touted as deep cycle actually aren"t & have fewer batterys series together. :dono
we like the reconditioned ones here , cheap as it gets, at typically less than half the normal price and warrantied for a year .
I have had to replace 2 Everstart batteries in less than 16months. Switched brands.
