11.6 while starter is cranking isn't really bad- that's a heavy load.
Make sure your connections are solid- if possible use CLAMP on terminals, then use the stud on that terminal to connect cable lugs.
ENGINE CABLE FIRST, remaining ones Largest to Smallest, and finish off with a Stainless Nylock (pre-thread on a bolt FIRST).

Looking at getting a new dual purpose battery for a 1999 250 pro xs. Should I go with the X2 AGM or the Dakota lithium dual purpose?
No such engine. Better clarify the engine before we answer.Originally Posted by jp24ducks

Which battery should I go with that is the least expensive yet still meets the requirements? 08 250 pro xs, graphs, livewell, etc.
The cheapest battery that meets the requirements probably won't be very good in a bass boat. The requirements in this thread pertain to operating the outboard and associated equipment which means 800CCA and 135 minute RC. An Interstate 24M-XHD meets that requirement for $123, but you will not be happy with it if you have electronics and try to run livewell pumps and shallow water anchors etc..
The Duracell 31 marine AGM from Sams is the cheapest I'd even consider at $180, but if you put much of a load on it may not last a long time. 800CCA and 200 minute RC.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
Can this Battery thread be updated to include Lithium Starting Batteries?
Not at this time, as some engines referencing this thread cannot be used with Lithium Batteries.

Could you update those engines that cannot use lithium starting batteries?
V-6 and V-8 Fourstroke Models Specifically REQUIRE AGM Batteries- and are not suitable for use with Lithium Batteries. Since the original post is not about Lithium Batteries... that's about all we should add here.

Dont let the Farm and Truck label fool you. This is one powerful battery ( check the specs only ) and you get another 25% off if you give them your email.
I was advised by Battleborn Lithium batteries that their lithium batteries, although have worked, they still would not advise them as a starter battery. Trolling motor batteries only.
I've got a limited amount of room where I can put my cranking battery. I need a battery that has a max length of 12". '08 250 pro xs, power poles, livewell, graphs. Is the odyssey pc1500 my best bet?
You are just over the threshold with that battery, so it’s not a good choice considering it’s $300 IMO. But if space is that tight you might not have a good choice. If you don’t tournament fish, don’t have a big electronics load and you run the outboard a lot, you might be okay. Otherwise you need to figure out a way to get a bigger battery in there.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
What I need is a good group 34, then a short fat tractor agm to run in parallel. That should get me what I need.
Not a good idea. Don't recommend parallel batteries for cranking- certainly not batteries that are not identical.
Good idea to open a separate post for your engine/boat, perhaps post a picture or two of your battery compartment for suggestions.

Currently have an Interstate 24M-XHD, which came from the factory on a new '18 Nitro Z19 Sport with a Merc 150 fourstroke. I have tons of room in the rear compartment for a larger battery. Just installed a Noco Genius to charge/maintain. Pretty vanilla setup.
I've outfitted the boat as a striper machine, and when I go out the average trip will be 8 to 12hrs. Don't really want to depend on alternator charging, as it's often been the case that long runs are infrequent.
I want to ensure that my battery will be able to crank the 150 a few times and at trip end, considering the following draws:
- HDS Carbon 12, operating for 8 to 12hrs;
- StructureScan 3D module, operating while Carbon is on;
- 30 gallon standalone bait tank for shad (powered by 500gph pump, ran nearly constantly);
- standard marine stereo, no amp, for background tunes; and
- boat's LED navigation lights, usually on all night long while striper fishing.
I'm thinking the factory battery isn't gonna cut it, and I don't want to risk a 5+, or many more, mile limp back to the landing with the trolling motor.
I want to stick with lead acid for consistency with my TM bank. Thinking that a decent 31 size cranking battery would be a worthwhile upgrade. Max budget is $250. Any advice? Thanks.
