deep cycle battery

Hey, I was wondering if there are any high performance deep cycle battery's like optima but a generic name? Just wondering because it would be nice to save a little money instead of spending 145 for a yellow top. thanks Mike

Re: deep cycle battery

does anyone know how many amps the optima yellow top puts out? In the magazine it says something like 800? But on my dads boat his marine battery is like 105 amps. For the most part I just need a battery that will turn over the jeep well, and I am running a 250 watt amplifier, and a set of 50 watt fog lights. Right now each time the bass hits in my jeep my lights dim, and also the battery will die after turning it over for 40 seconds. So before I ruin my alternator too I want to know how many amps I need and weather to get a marine deep cycle or an optima.

Re: deep cycle battery

you dont want a deep cycle battery for any type of cranking chores, thats not what its designed for.

they are rated in amp/hours, for instance 120 AH
means it can deliver 12 amps for 10 hours steadily.

or 30 amps for 4 hours

but it willnot have the large amount of amperage to start an engine, and it will ruin it trying to make it do that.

deep cycles are for long duration moderate to low amperage drain applications.

GnB used to make good ones, I always had good luck with them in my boats.

about $70 the last time I bought one, and it lasted 6 years

Re: deep cycle battery

Feel free to correct me anyone, but pby, if your lights dim while your stereo peaks out its power draw, your battery is not to blame.

Stereo design is not my thing at all, but I believe that they make capacitors that are designed to store the energy that your subs need at peak so that your battery/charging system doesn't take the hit.

And, if you're concerned about the cranking life of your battery, get your engine tuned up so that you don't have to crank it over for 40 seconds. My truck has the much maligned BBD, and I never need to crank it for more than 5 seconds to get it to start, even in the dead of winter. your profile doesn't show what your jeep is, so I can't go any further in that vein, but if you are running a 258 or 360, do the tr upgrade!! Starts are much improved, and I am positive that the upgrade will lengthen battery life.

When the engine is running, your alternator is responsible for the draw of your system. if your accessories are overworking your alternator, putting in a high test battery will only help your alternator suck money out of your wallet. The alternator needs to be upgraded first. Brendan

Re: deep cycle battery

Ozark...It's really not that bad, I heard that myself, but it's not true. I ran a Wonch deepcycle 208 a/h for years as my only battery, it had about 700 cca and worked fine.

Re: deep cycle battery

that must have abeen a mraine cranking/deep battery dirtdog.

ive had several deep cycles and they wouldnt crank an engine.

if it had 700cc it was a combo cranking/deep cycle, not a straight deep cycle

Re: deep cycle battery

Dont get me wrong my jeep starts fine, however the other day when I went wheeling everything got a little wet and in about 40 seconds there the battery didn't have much juice left. So in a situation like that I want a bigger battery that will crank until it starts.. I was told that the amp for my stereo is sucking to much juice and that I need to get a new battery before my alternator goes. Well thanks for the help guys, ozark I know what the ratings are now. I'm still confused as what to get though! So someone please tell me what I need to buy.
