How long does a Genesis Battery Last?

[Cut-Throat]

A tough question I know. For the last 25 years I have replaced my Cars Battery every 4 years and it was the best Car maintenance decision that I have ever made.

I usually picked out a nice warm day in the fall and bought a Diehard at Sears and replaced it myself. I keep my cars 8 years and replaced the battery at midpoint of my ownership. I did not wait for the battery to die on some day when it was 20 below zero and there were hundreds of people at Sears buying batteries. Also the battery I wanted was in stock.

The Genesis could be a 'different animal' though. The battery is huge and in the trunk, so that it is protected from the elements. So, I was wondering how long do they last and how much do they cost?

Even though the battery is protected in the trunk, I'm sure that factors such as ambient temperature extremes affect longevity. I know that mine still seems (and tests) fine after 3 1/2 years, however.

Your question reminds me of a story that was attributed to a famous cardiac surgeon. When asked by a patient who had had a heart valve replacement "How long will it last?" he replied "The rest of your life." Don't know if this is urban legend, but it's been fun to quote at medical conferences.

I have a 5 year battery life experience with my prior cars. My hunch, the Genesis is no different. My old cars had batteries in the trunk. The heavy electronic demands and discharges kill them faster than ambient temps, I think.

Still on OEM battery from 2008. Tons of life left still. I don't replace the battery until the CCA's etc. are at a low. I test the battery about twice a year on my vehicles.

This is a pretty comprehensive article. It mentions that "only 30% of batteries sold reach 48 months." Also useful description of AGM characteristics and features - AGM have been my replacement batteries of choice.

Interesting article. Thanks!

It sounds like 48 months is the max time anyway according to the article. I;ll probably just keep doing what I have been doing. And hope that it lasts 48 months!

My original battery was replaced under factory warranty and it was about 18 months old

OEM batteries on Japanese cars usually last longer that that in my experience. My Genesis battery is now 64 months old and in very good condition, although I usually only drive about 3-4 days per week and have only 48K total miles. I also park my car in an attached garage and live in a moderate climate.

Heat is one of the things that kills batteries, simply because it can lead to structural failure of the individual cells. The one time I had a sudden failure of a battery was in over 100 degree ambient temps (and even hotter than that in the engine bay). Having the Genesis battery in the trunk does help some, because it stays a little cooler than it would in the engine bay.

My battery gave up the ghost with 5years of great service. 2009 Genesis Tech who lives in Vancouver BC and is garage kept. Car is sunny day use only and has 28000kms on the dial. That is 17398 miles for you post Jimmy Carter people.

 

[Cut-Throat]

Yup, it sounds like I'll continue with my Replace at 4 years program. I've never been stranded or inconvenienced in the last 25 years doing it this way!

I see Sears has a Diehard that will fit my 2011 Genesis for $162. Not bad.

Great to hear that sears has a battery which will fit the Geny. $162 is a good price.

Temp in this case is really very minor influence. I am an engineer in the battery industry.

It really is about two factors. The number of cycles and the depth of discharge. Both have more effect than anything else. When a car sits, there is constant slow drain. Depending upon the depth of discharge this will cause reduced life. Also, number of physical starts matter. However the starts are less damaging than the long sits because of depth of discharge.

Example - I had a 2003 F150 which I bought new. It was my daily driver. I sold the truck in 2010 with the original battery still in place.

Example 2 - I had a 2010 Mustang. Mostly sat in the garage and only drove it on weekends and occasionally otherwise. I replaced the battery in 2012 just before I sold it because of total battery failure.

Lead acid batteries of our generation and design are good for about 600 cycles of greater than 10% depth of discharge. Meaning if they remain 90% state of charge or above. When going lower than that the life will fall off rapidly.

If used purely for starting, you can expect a long life because the depth of discharge is minimal per single start.

Further, if the battery does discharge much, it likes to be brought up slowly. However the alternators in our car is designed to bring the charge up rapidly by design due to the duty cycle of most drivers.

I agree that temp does not have a big impact on how long a battery keeps it charge. But when there are very high ambient temps (100 F for 30 straight days) and one is driving in stop and go rush hour traffic every day, the structural integrity of the battery can be compromised more easily in hot weather, especially if one hits a pot hole, etc. That is why some batteries come in North and South versions. South batteries have thicker interior walls to withstand the stress caused by high heat and physical jarring of the battery, which can lead to almost sudden and total battery failure. North batteries have thinner interior walls, which allow for reserve power in cold weather.

You are correct. However for the most part, this has been designed out of modern AGM's. But overall, you are right on.

The major cause today of battery failure though is not temperature. It's purely cycle and usage profiles.

I agree about AGM, temp is not important. I also think that the Genesis Tech Package puts a bigger strain on the battery than the non-Tech Package models. That just comes from reading about other Genesis owners and their battery problems.

Oh for sure. I agree completely with you. The draw on the tech package is fairly large. Even when I turn the audio system on in the accessory position, there is a warning on the navi screen telling me basically to start the car. Lol.

Not sure of the actual current draw, but it won't take much to get the battery under 90% or 80% or even much less in regards to depth of discharge.

Some have commented on the relative size or the battery compared to some other cars. There is a reason for the large size and it is due to design of reserve capacity. Lots of electronics and a powerful sound system equal lots of work for the battery.

Mine just died as the coldest day so far this year arrived (28 F last night)
It was the original and it went 65,000 miles in 5 years and 6 months.
You need to replace the Genesis battery with an AGM one to prevent explosions in the trunk which are very inconvenient.

Auto Zone has one with 3 yr warranty for $175.00

My Genesis is now 6 years 5 months old. It is parked in the garage and mileage stands at 27,000. Battery was checked by dealership last week when having its annual state inspection and I was told that the battery is in perfect condition and does not require replacement.

You're running on borrowed time.

My 2009 battery will be 7 years old in January. I only drive about 2-3 days per week, and have 53,500 miles.
