Deep cycle?

[steplift20]

I just picked up a group 24 battery it has 1000 cca for my 115 Yamaha 4 stroke
I didn't look at the battery when I picked it up and when I got home it is a deep cycle battery I think that shout be good, for starting my engine and he electronics My question is this First will that battery be good? And what is the real difference between starting,duel purpose and deep cycle Thanks guys Next time I'm going to take glasses with me

something isn't right, group 24 1000 CCA is very strong, that's about 1200 MCA. Most group 24s are 850 cca/1000 mca. nd most deep cycles are group 27s, and generally max out at 550/650. Check again on that battery. 1000 XXA should spin your motor over fine. Normally on a deep cycle, the discharge rater is lower so the recharge rate will be also, with a 1000 CCA that's a pretty steep discharge rate, so you should be fine on recharging with that Yamaha/

It'll be fine. Better actually. Deep cycles are better for running lots of electronics, lights & pumps & motors for hours. They are supposed to be discharged and charged over and over again.

Starting batteries are designed to shoot their load in order to crank a big old carbeurated Mercury five times in the hopes that it starts. They really are not supposed to run electric loads for hours.

Your 4 stroke is going to start in a half second every time so you don't need a dedicated starting battery.

The compromise is a Dual Purpose (DP) battery. I ran a single group 27 DP for the 18 years I had the V20. No battery switch, never put it on a charger except in the spring right before hooking it up. Needed a new one every 5 years... like clockwork

and I was also going to say that 1000cca sounds like a lot for a 24 DC

if it has a computer running the engine, 850 CCA minimum, don't mix batteries due to different charging rates. You can use some isolaters to charge house batteries at a different rate, but its just one more thing to fail. Dual purpose batteries do neither job well. The only time you need a deep cycle on a boat is if you have a trolling motor or a house battery bank

I have to disagree, any quality deep cycle battery will do the job of starting any outboard on the market. If you run alot of electronics like me, that's all you want. Personally I run 2 dekaney group 27 deep cycles on my boat. I start a 200HO Etec, have 2 vhfs always on, hds7 gen2 and a elite 5 sounder along with radar, 2 meter radio and tunes, most of the time everything is on but the radar. No problems in 10 years, so far.

Just because you can, does not meen you SHOULD. Deep cycles can give high amperage loads when needed for starting, but any good deep cycle battery is designed to put out low to moderate amperage amounts for longer periods of time. Using true deep cycle batteries for cranking WILL shorten the batteries life, that's an undisputable fact. The thing is there is very few TRUE deep cycle batteries in the group 24/27 range because they know people are going to abuse them as starting batteries. True deep cycle batteries will not have a cranking amp rating, only amp/hour ratings which is what is important to a deep cycle battery.

X2. A regular car battery, either traditional lead/acid or AGM (Absorbed Glass Matt) is more than sufficient for most boats. If you're running an electric trolling motor from a small skiff or rowboat then a deep cycle battery comes into play. But for regular day to day usage just a straight car battery is fine (And usually costs less) By way of further explanation, allow me to copy/paste a quick article about the types of batteries. (Keep in mind this does not include Lithium-Ion batteries which are very expensive and not really practical for boat use unless you have an electric powered car or boat)

Types of batteries:
1) Wet/Flooded Battery: The wet/flooded battery is one of the most popular types of batteries. It is so popular because the battery price is very low. The battery design uses plates that are freely suspended. These plates are insulated from each other as the negative plate is completely sealed in a separator bag. These are maintenance free and sealed so no gases are replaced. The fluid in the battery will last until the battery dies and you do not have to keep topping it off. These batteries can range from $50 to several hundreds of dollars depending on the brand.
2) Calcium-Calcium Battery: This battery has a calcium alloy that is on the different charged plates. This calcium reduces the amount of fluid loss and the rate of self discharge is much slower. The main disadvantage is that you can seriously damage the battery if you overcharge it. The bubbles that move through the fluid are important, as they are responsible for mixing the different acid densities. You can find a calcium-calcium battery for under $100.
3) VRLA: The VRLA stands for a valve regulated lead acid battery. This name really describes the safety valves that are on the battery box. The safety valves are all pressurized. By containing the gas in the battery it will mix and form water so you stop any fluid loss. There are two main designs of this VRLA battery: AGM or GEL. A GEL battery uses silicon to make the acid more solid and like a gel. This type of battery is very good but is not the best for a starter battery. This type of battery costs between $100 to $250.The AGM battery uses absorbed glass matt. The matts are very thin, which keeps internal resistance very low. This makes it a perfect battery for starting a car, as you can get a lot of power out of very small volume. AGM batteries price range anywhere from $50 to $300 depending on the brand.
4) Deep Cycle: A deep cycle battery will provide power for a very long time. These are typically used on small boats, golf carts, or electric vehicles. You will also find these used to collect and store solar and wind power. These batteries have thicker plates inside the battery as this increases the capacity charge. They are typically not used for cars or boats because they have a high discharge rate, so the battery will run down very quickly. If you do not drive your vehicle for a long time, then you will not sufficiently recharge the battery. Deep cycle batteries are expensive and starting prices are about $200.

Hope this helps clear up what kinds and how these batteries work.

Direct injected 2 stroke power with 2 1000 MCA Interstates on an Awl gripped hull riding on an aluminum I beam bunk trailer without any brakes pulled by at least a Chevy or gmc if not a Toyota.

Tell Charlie to get the white one with the tailgate, MJ to hard wire the float switch to the battery, and Stinky Hooker to put some pants on.

Sorry, I still disagree with you, I sold Deka(east Penn manufacturing) batteries for years and had factory training. Some manufacturers, maybe, not all batteries are the same despite their purpose. I will leave it there.

I guess we all got to the bottom of this topic....
