Deep Cycle Battery

[Rico]

Hey guys,

I need some help. I want to upgrade my battery to a DeepCycle battery. I've been looking towards an Optima YellowTop but I can't find any of them that fit, that have reversed posts. Any ideas on that?

CrappyTire has a DeepCycle battery and the terminals are on the middle of the battery. Any idea if the terminals will reach the posts? I don't have time to check it out. Sad, but true.

Anyways, any help would be great.

Thanks!

Rico

Uh, you probably don't want to change to a deep cycle battery. It's completely different from a conventional car battery.

A conventional car battery provides a whole lotta amps, because turning over an engine is hard work.

A deep cycle battery provides low amps, but can do it for a very long time. These batteries are used in cars in a dual battery set up, to keep accessory gear running that takes a lot of power (like fridges in 4WD's, or in some cases massive stereos). This way when you get back in the car after running your whatever your cranking battery isn't completely drained.

Well I do have a stereo system in my car. That's why I wanted to switch to a deep cycle. I still want to upgrade the battery in general cuz it's the factory battery still. I'd like to get more (even if it's just a little more) power to my amp without having to install a second battery system.

Ah right, well if you want to be able to run your stereo for longer with the car on accessories then you can buy a bigger cranking battery. Obviously not so large you can't fit it in the engine bay.. But the bigger cranking batteries will allow you to run the stereo for longer without flattening the battery or having to resort to a dual battery system.

You can't put in a deep cycle though because that type of battery won't be able to start the cars engine.

Other things that might be worth looking at is the electrolyte level in the battery (if it isn't a sealed unit). If it has little screw open things on the top, then you can check the level of the fluid, top it up if needed with deionized water. Theres nothing wrong with the shop battery though, if its not broken its waaay to expensive a part to be replacing for no reason.

have fun

I've been looking at the YellowTops cuz Optima states that it's a dual featured battery; for starting & deep cycle.

High crank doesn't mean high capacity. All the Optima are not bigger but smaller. Go to the Optima website and do some reading.

What doesn't fit again?

higher cranking is only really good for diesels... they require it since they have to turn over and compress the fuel to get it to ignite. Rather than with a gas engine that only needs to crank enough to have a spark go.
thats why most 4 cylinders have such a tiny battery and why v8's don't have huge batterys to start. and why diesels have larger batteries...
he doesn't want higher cranking amps.
he wants capasity...

heres what you do, relocate your battery to trunk add another one and run the two together in a parelle system

Just get a Optima Red top. Plenty of power not as high of a cost. Lets put it this way I ran the stereo on my truck (93 OJ Bronco) with the subs going for 8 straight hours (I was changing the radiator and electric fan) and all was powered just fine. Then when I went to start it it still had plenty of juce in it to fire up the truck. I have a 200 W head unit (I know big whoop) powering 4 speakers and a 1500 watt amp powering 2 12" subs. Red top will be fine for you.
