Good question for the Yamaha boards.Originally Posted by slim

Don / CatFan, could I get your thoughts please. I have a 175 Opti (non Pro-Xs) and an Odyssey 34MPC1500 (850CCA, 1050 MCA, 135 min reserve, and 68aH capacity) a couple years old. I don’t fish tourneys, and don’t have any power poles, nor do I use live wells). I currently have 2 small Fishfinders that draw about 1amp each when on but usually only have one on when not running the Opti. Never had a problem. I’m looking at getting a new Fishfinder for the bow, which apparently draws 2amps. The odd time I may have both on, so may draw about 3 amps. So, what I’m wondering is: i) with the battery described above, assuming I draw 3amps when not running the Opti, roughly how many hours of battery use would I have such that I could still crank and start the Opti and get back to the dock? ii) under the same scenario, if I got a NorthernStar NSB AGM 27M (930 CCA, 1080 MCA, 195 Min Reserve, and 90ah) again assuming I’m drawing the same 3amps, when not using the Opti, how many hours would I get so I could still start the Opti?
I know the specs on that 27 series battery are better, but I’m tight for space and not sure yet if I could even fit in in.
Thoughts / comments?
NorthStar NSB AGM 27M
Really should keep questions specific to one boat/engine combo in a separate thread or post (since we're already on Page-37 of this thread, especially).
Given you specific setup, and your specific usage, with no other additional power-consuming products in the boat: You are likely fine with the battery that you have. If you alter your usage to utilize livewells or pumps, or upgrade to larger graphs, I wouldn't recommend either battery.
While it's possible to compute the power consumption of your X and Y graphs over time, what's not possible is to compute the condition of (and charge condition of) your battery at any given time. Theoretical computations are great, but they often differ from the "real world" applications.

Thanks Don. As a newbie I’m just trying to figure out the boards and rules. FYI, earlier today after I posted I had a chat with a Canadian Odyssey rep and he thought with my Odyssey 34 series battery I would only get 5 or 6 hours of use at 3 amps draw before it might impact the ability to crank my Opti.
The factor that makes any estimate unreliable, other than battery age and condition, is outboard run time. If you run the outboard enough, you can fish for days.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
crazy Mercury requires an AGM on the v8 fourstroke yet you can upgrade to a Lithium cranking battery on the Ranger website while rigged with a Merc v8 Pro XS.....so if I did this and ordered a new Ranger would my outboard warranty be voided?
I suspect your boat order would end up modified before you took delivery- unless whomever rigged the boat and completed the PDI simply didn't read the materials.
Regardless, the Engine Warranty and Exclusions section of the Owner's Manual explains what is, or is not covered under the Factory Warranty.

I will wait awhile on swithcing to lithiums, aside from fire danger which may or may not be true when the go out its poof, no indication they are getting low, its all or no power with those. I remember a bassmaster fisherman on the Sabine river event who was a new lithium Pro and it they stopped working and possibly cost him a win and they tried the best to keep what the equipment failure quiet.
Purchased a boat with a 07 225 optimax. Previous owner was still using a group 24 battery...
Ended up going with the NAPA 7235. The specs make it look like a beast of a battery almost on par with the AGMs and less than half the cost... 1000CCA, 185 RC, with an 18 month warranty.
I appreciate all the information Don. You saved me a lot of trouble this season.
How much can you get those for? The Napa website lists those for the same price you can get a group 31 Duracell AGM at Sams which seems like a much better deal.
$140 + core charge picked up 5 minute drive from my place. I'm not a sams club member, nor do I live near one so that wasn't an option for me.
Thats cheaper than the website, they are $170.
List price was $155 with a 10% discount for AAA members. Most NAPA stores are independently owned an operated so I'm sure they have some freedom over the price.
We also have an East Penn wholesale store in the area... Could just be a function of the price to get the battery to the NAPA store. Shipping a 60lb battery ain't free.
Anyone using the commercial batteries listed how well do they handle graphs, power poles, live well pumps and other accessories? I can get the Exide group 31 commercial batteries for $80.
I changed to a commercial 31 this year. I read so many good reviews on the Sams agm. it worked ok for a year but spun my boat slow last year. Only couple trips on new battery so far, but seems really good. Starts my proxs faster than the Sams battery ever did.

That duracell is lacking the CCA (800 cca) bare minimum for motor only with no other loads such as electronics, pumps, etc. the Napa commercial is far superior to the duracell
Thank You Leon Pugh
Back in 2019 I added new batteries which included 3 Duracell AGM 31's from Sam's for my trolling motor batteries and the Interstate 31-MHD as my cranking battery, graphs, pumps, etc.. They have been great with no issues but the Optimax was still more sluggish than I would like to start even after I added the Interstate 31-MHD. Recently I upgraded a bunch of stuff and now I have a new ghost TM, Active Target, 2 12" HDS Lives and one 12" HDS Gen 2 touch from before. Went out yesterday and about 8hrs in the graphs started shutting down. Yep, battery was dead. TM batteries were still probably 75%. Anyway, Jump started and made it in but looking for what battery I need to have in order to be able to fish a full day? Please keep in mind I ran the Active Target, and the 3 12" Lowrance units all day without putting any in standby and also I didn't run the big motor much at all. So clearly I can be more efficient by putting stuff in standby which will help but I wanted to see how everything was working. Anybody have a similar setup with a 250 Pro XS and running 3 12" units plus active target or similar? If so, what cranking battery are you running? Any input, thoughts or suggestions would be appreciated.
The best battery choices are listed in the top chart of the very first post to this topic. Next best, non-AGM choices are listed in the second chart. JMHO, and I'm not running multiple graphs, pumps, livewells, power poles, etc., but refuse to use anything but the biggest AGM with highest CCA and RC in my boat (Northstar 31AGM). Pay once, cry once, enjoy peace of mind for years. YMMV.

What if a battery tests above 800cca but isn't rated above 800cca?
