Someone was telling me you could run marine batteries in our truck! I know you can get a better CCA then regular batteries! But I was thinking about the longevity of the batteries!!

 

Yes, but why would you?. I just did the opposite. I use power stroke batteries in my boat. You can get motor craft batteries for $100 and marine for $240. Just say'n

 

i buy deep cycle marine batteries because they last long have a higher cca and reserve amp capacity as well as the amazing accessory connections that i love to utilize with my stereo systems and lights and other electrical additions!

 

X2 "Marine battery" Just means it is a deep cycle battery with screw type connections.

Deep cycle batteries do not have higher CCA on average, they are made for continuous current draws for long periods of time. Starting batteries are made for the quick high current draws that you need to start a truck...

(I too run an automotive starting battery in my 302 V8 powered speed boat)

 

I don't know why you would want to run deep cycle batteries. They cost more, won't last longer in that application, and may not crank the motor as fast.

In simple terms:

Starting batteries are designed for high instantaneous output, but do not tolerate deep discharging very well. Running them down to 50% a few times can kill them.

Deep cycle batteries are designed for lower amp output over a long period of time, and tolerate 50% discharging and recharging well. They may not provide the level of instantaneous amps that you want to crank a starter.

Not to overstate the difference, and they may work just fine in a truck. But they cost more for no advantage in that application, so why would you?

 

Don't do that for the money all your paying for is how long they last without a charge

Spend the money and get die hard platinum

 

I all ready have new batteries in my truck, I just heard a friend talking about it!! Y'all must not no to much about boat batteries, because they make a starting battery too!! CCA 950, your outboard has a alternator on it just like your truck!! And really y'all, you can get Walmart Marine battery for about $100 dollars! Now I'm not talking about trolling batteries,theses are marine starting batteries!!

 

Maybe, maybe not. But you're the one who came to a truck site asking questions.

 

If you want to use marine batteries in your truck, go ahead, it will work just fine. If you want to use deep cycle batteries you might want to reconsider. The main difference in the three types is the thickness of the plates and power output. A starting battery uses lead sponge type plates, lots of surface area. They put out maximum amperage for a shorter time and are designed for starting engines. Problem is, the plates are quickly used up (literally crumble and fall to the bottom of the case) if you discharge it too far, too often. A true deep cycle battery can have plates of solid lead 1/4in thick or more. Peak amperage output is less but for a longer time. They can be discharged 50% (some designs down to 20%) many many times before the plates start to go away. A marine battery is somthing between theses two designs. Sad to say the terms deep cycle and marine have no hard technical specification, just general descriptions and inexpensive battery makers use these terms loosely. Definitely one of those times whe you get what you pay for. If you check your marine battery for example, it will likely be rated in "marine cold cranking amps" instead of "CCA". Also, if you compare that rating to the CCA @32* the marine battery will be usuially be less, while a starting battery will be higher. (my 850 CCA starting batteries are rated at 1,000 CCA @32*) That indicates the first measurement may have been fudged (taken under some extreme ideal condition) on the marine battery. Different battery designs exist because there are different requirements for different applications. Using the correct type for your application will get you the best power and longest life.
