Autozone Duralast Deep Cycle Battery

19 posts in this topic

Posted (edited) · Report post

I was shopping around for batteries today and I found this battery. They have two sizes. one that has 1000CA at 32 degrees farenhight and 800CCA. then a size that is a lil smaller. The big one is $69.99. This bat has more CCA than the Optima yellow top if i can remember correctly and its jsut a fraction of the yellow tops battery. So my main question is. Is this Duralast batterie worth the price?

My general rule of thumb is, you get what you pay for.

It seems to work that way in alot of cases.

but i am on a fixed budget. i'm a highschool student that don't make that much. haha. but ya. i don't know. i could get this duralast and if it goes bad or not work great i can save up and get an optima or kinetiks or somehing like that. i don't know.

The duralast DEEP cycle means you can drain it down to zero volts and recharge it just fine...assuming you don't "abuse it".

It will however be OUTPERFORMED (i.e. more cycles per battery life, and quicker recharge/discharge time) compared to an Optima.

It's a "regular" deep cycle and is not inteded for ABUSE.

The Optima is a much more "over-engineered battery" much like a Stinger/Kinetik/Odyssey/Powermaster etc. Those batts are designed to PERFORM under ABUSE...therefore, they are overkill in your standard battery role (some folks live by overkill) and would be a better idea for someone planning on adding a lot of strain on ONE under hood battery (i.e. a large amp drawing mucho current).

The Duralast Battery would be fine "for now" ....but despite having MORE CA/CCA than an OPTIMA, it is not neccesarily "the better battery" for your application, especially in the LONG RUN/battery life.

Most over-engineered "overkill" style batteries that are better suited to an audio setup BECAUSE they are capable of PERFORMING even under extreme strain (high or Low temps, High or low voltage/massive drops, slow recharge rate via a stock ALTERNATOR, High resisitence "systems" with undergauged wire, etc) whereas the Duralast battery will show more CCA's...it is more likely to fail under "abnormal strain" (i.e. what I mentioned above)

The other issue is the Duralast is a Lead acid battery. The kind that have thick lead plates inside surrounded by sulfuric acid. They ARE NOT maintenance free...whereas OPTIMAs ARE maint. free AND you can mount them in any position you want without fear of SPILLING the acid out.

Not to mention, if you allow the acid level of a lead acid battery to drop too low (it will evaporate out over time and BOIL out under strain), when the battery is in USE the Lead PLates inside that are "exposed" HEAT UP more than normally ( plates not surrounded by the acid due to it being lower than normal and leaving the top part of the plates EXPOSED and DRY) and the acid inside the battery will boil, turn into Vapor... acidic vapor that will VENT OUT of the battery (they are designed to do this) and these gases smell like a NASTY egg fart due to the "sulfur gas". The gasses can cause headaches/nausea and just plain smells nasty.

I would say the DL deep cycle would be OK as a "for now" fix AS LONG AS IT'S UNDER HOOD OR IN THE BED OF A TRUCK....Not in the cabin with you...YOU DO NOT want to be breathing that sulfur gas all day.....but if you are going to be using it as the MAIN under hood batttery, I would recommend a DUAL PURPOSE battery or a decent starting battery under hood AND a deep cycle, along with an upgraded Alternator, that can keep up with charging them both.
