How long does a Genesis Battery Last?

[moe92882]

I own a 2012 3.8L Tech package Sedan, I was told by the dealer and later confirmed by Autozone that my battery was "bad" and it needs to be replaced. The dealer wanted 300 however; I replaced it myself for $152. I have made a video on how to replace the battery, you may checkout the below link.

I replaced my battery today. It was the original battery and was manufactured February 2011 (Code B1 on battery). I bought the car on Tuesday with 74k miles. It still started the car, but I was a little worried about its state. I have a second job at Oreilly, so I tested the battery in the store, and it was bad. With my employee discount, I got this bad boy for $143.

It's a Group 95R (H9) AGM with 950 CCA. The Group 95 battery is about 1 1/2" longer than the Group 49 (H8), but Hyundai was nice enough to put a second threaded hole in the floor of the trunk that allows the installation of the larger battery. I used this exact battery in my M5 as well, and discarded the foam spacer that BMW installed in extra space. The original Hyundai battery was only 780 CCA, so this one is slight overkill.

I ran the multimedia system for about 20 minutes with car in ACC mode and the battery almost would not start the car. It cranked eventually but should I consider this a sign of a weakening battery or is this fairly normal for this vehicle? My older vehicles could push 700+ watts of audio system for at least this long without breaking a sweat and start the car right up.

I got 7 years with the battery in my 2009 Genesis, to say I was surprised was an understatement. I had the car for 7 years the battery in fact was several months older. Go figure

Mine lasted 8 years, and seemed perfectly fine when I recently replaced it. But I only use my car about 3 times per week, and it is always garaged when not driving. Also, I don't have the Tech Package.

I typically change my battery on any car after 3 years. I live in north Florida and as you can imagine the summers are quite brutal. I believe that with the fact that the battery is in the trunk and I have the “all you can eat package” ( Pardon the Pun ) I believe it just makes good sense to do this. I also am a big believer of getting the best battery for the job. I am also mindful of prices and don’t mind shopping around either. I have only ever had a single early failure of a battery and believe this or not, I took it into Advance Auto and they tested the battery and said it failed there tests. They gave me a brand new one free of charge and gave me $10 back as the battery price had dropped. Go Figure.

Due to the heat here in Florida I am more concerned of breaking down in the heat than in the cold

Heat can definitely weaken the structural parts of the battery, and along with vibration or physical shock, lead to physical damage that can compromise the integrity of the cells.

Some batteries come in North and South variations. The South ones have smaller cells because they have thicker cell walls that hold up better even though they have less cranking power for a given battery size. On a larger battery size like H8 or H9, I have not seen that option. AGM batteries are best at holding up to heat.

Every 4 years? Wow what a waste of money.

Battery in my wife’s 2007 Camry was 10 years old when we traded the car, never an issue.
Battery in my 1939 Ford Tudor is nearly 12 years old. And that car only gets driven about 1000 miles a year.
Battery in my 2001 Silverado is an optima agm battery going on 16 years.

The only battery I ever recall changing at less than 10 years was in my nieces 2011 Malibu and only because she left the lights on one night and we couldn’t get it to take a charge or jump, and it was 6 years old at that point.

The OEM batteries in both my Genesis sedans failed at the 5 year mark in Florida.

Thinking about replacing my 2009 Genesis battery this month. Original battery, 9 years old, 180K on the ticker- awesome battery, awesome car.
Always garaged, but in Connecticut goes from sweltering heat to occasionally below zero.

I would have replaced it 3 years ago before the winter! Nine years is exceptional.

......My 2009 4.6 purchased in late 2008 battery lasted almost 8 years with only 85K miles............Now i decided to use it for Uber since it looks like i bought it yesterday but the mileage im noticing is piling on & on & on...........smh

My 2009 Genesis 3.8 V6 still has its original battery with 135K miles on it.

I appreciate this threat on Genesis battery life. My 2013 Genesis 3.8, no technology package, is working fine but it's 6 years now so I'm on the fence on getting a new battery. Our 2013 Toyota Sienna battery died after 5 years and it was inconvenient. My old Elantra's battery died after 5 years and it was a hassle. I would like to push it to the limit just for fun. Anyway, 6 years, never tested but working fine. I'm in Colorado and the weather can go to extremes. Perhaps I'll get it tested. Thanks to everyone for the inputs!

At 6 years and winter coming, I'd have changed it out last November. I guess it depends on you pain tolerance.

Mine is 4.6 with Technology Package and the battery died at about 76k, about 5 years 7 month from purchasing the car new. But then the alternator conked out at 96k too and the alternator and the belts were subsequently replaced at the dealership. The Bosch battery with 36 mo replacement/96 month credit prorate purchased and installed at the Pepboys in October 2015 is going strong with no issues. The best bet is to have your battery tested.

I bought my first gen (2009) used in June of 2009 with 2600 miles on her clock. I've commuted in her nearly every week day since. She has 167,000 miles and still has the oem battery installed when manufactured. I've lived in MD, WV and NC just to give an idea for weather. The car still drives as good as new with one exception. The steering feels a little "lighter" then before and on center is not as good. Probably some bushings and she'll be good as new.

I replaced the battery in my 2009 last year as a precaution, sat at 12.3 volts fully charged. But it still worked just fine. It was also the original battery.

My 2012 3.8 is garage stored and has 26,000 miles. The garage is heated (Northeast USA). I drive it on weekends - no wet weather. Yes it is pampered!
The battery has just died. I do have a battery tender and use it during the winter. The comment above were helpful. I will be jump starting it today and see what happens. I am the belief that it is time for a new one. Thanks again.

 

[G-804488]

I have a 2013 Hyundai Genesis 3.8 bought new, I live in a mild climate, it has 130,000 miles on it. Drive it everyday, thinking about replacing the battery.
