Boat battery, what’s the difference?
Hi all - I need to replace my secondary battery in the boat but was looking at using the same battery to run the fridge for camping (which would be a couple of times a year)
Is there any reason why I can’t use a normal kings battery in the boat like the one in the link? Or does it have to be a marine battery.
Keep in mind, I’m only using my boat in the bay, if that makes a difference.

No need for a 2nd battery in the bay.As long as the original one is 3 yrs old or younger thats fine
The difference between a cartruck to a marine battery is the plates inside are bigger and wont flake off particles as you go over waves
People wont agree with me -But they dont know elect stuff
I replace me battery approx 3 yrs and I fish about 3/4 times a week never had a problem

Re: Boat battery, what’s the difference?
2nd battery is essential.
95% of boat break downs is caused by a flat or failed battery which is super easy to avoid by having a 2nd battery.
Marine batteries have thicker lead plates which makes them stronger and less likely to break/crack due to vibration.
Certainly worth having a true marine battery.

Re: Boat battery, what’s the difference?
Agreed you probably don’t need it. The boat is already set up for it and it gives me peace of mind so I prefer having the second batterydenis barden wrote: ↑Thu Feb 02, 2023 10:19 amJoker

I have a good marine battery in the boat now. I really don’t want to buy two battery’s.frozenpod wrote: ↑Thu Feb 02, 2023 12:02 pm2nd battery is essential.

So if I buy a normal deep cycle battery for the boat and maintain the primary battery as a marine battery, do you think that would be fine?

Re: Boat battery, what’s the difference?
Up to you, there is increased risk of faster battery deterioration and increased risk of battery failure.
It is not a huge increased risk so way that up with the cost.

2 battery for me.
To many boats kayak, helicopter , catch a fish,catch a fish
Re: Boat battery, what’s the difference?
Deep cycle batteries have thicker plates than cranking batteries so it should be OK to use the one battery for the boat & car, especially if the battery is fitted near the stern where there is less pounding. If it were a starting battery I would stick with a marine one.

Marine battery's are made for boats so why use anything else

Re: Boat battery, what’s the difference?
Generally speaking AGM's aren't designed for cranking. If the outboard isn't a monster it should be fine. Don't rate the kings battery's at all though. Had a 120ah agm for about 3 years and binned it recently. Got 6-7yo full river 120's still going.
Personally I've always preferred having a second battery on the boat.
I run an optima blue top that runs crank and all of my electrics except for the leccy. For that I've got a 100ah lithium which is charged by a dc:dc charger and has an emergency parallel switch incase it's ever needed for crank.
