Battery Life Expectancy?

[jep604]

Purchased my 2014 Genesis Sedan brand new in June 2014. Manufactured November of 2013. First battery died in December of 2017. Had the car taken to the same dealer where purchased where they checked the starter and alternator and then installed a new Hyundai battery that I still have installed.
Wondering if I should have this replaced before another unexpected dead battery?
Any thoughts or recommendations will be appreciated.

With winter coming, yes, I'd put in a new one NOW. If you live in the north, it is insurance against jump starting or changing out when 3 degrees.

Thanks, Ed. Will def get a new one when I return to the Mid-Atlantic. Currently back out west for two weeks.

7 years is entirely achievable with a trunk-mounted battery.

Put a Battery Tender on the battery for a day or two. Might just need a charge, and some tenders have on board diagnostics that will flag a battery that's developing a short or other issue. I do this quarterly with all my cars, and it always surprises me how much charge some will take even when used daily or bi-daily.

Check the electrolyte level in the cells. Add DISTILLED water (not tap) if the plates are not submerged to a fully charged battery (never add water to a discharged battery). And make sure the vent tube is installed.

All that said, a replacement battery is cheaper (usually) than a tow... and wintertime dead batteries are indeed No_Fun(TM).

Thanks for the input. Even with AAA, I think I will opt for the replacement now with winter coming soon. By the time I get back East, the car will have set for 3 weeks without moving. Fingers crossed it will start.

Can't do that with an AGM battery, which is what these cars call for.

Since when is the BH an AGM car?

If you have an AGM battery in your car, you should get 10-20 years out of it... as long as the charging circuit doesn't overcook it. And now my advice to put a tender on it is now double-strength. AGM batteries don't like being undercharged or discharged (and are a PITA to recharge when they do). Don't ask me how I know.

Honestly I don’t know. Second battery installed by Hyundai dealership where I purchased it brand new in June 2014.

I know my 2018 is AGM. I look up 2015 on auto store sites, and they show only AGM as fitting it.

Sorry, I missed that this was 2014.

It seems to me that it depends on how tolerant you are to a catastrophic battery failure. If you don't mind being unable to start and you and not out in the middle of nowhere, sure go 10 years or even wait until it does fail by itself. If you are not very tolerant of being without the car until you get a new battery or waiting for it to recharge (assuming it does recharge) I wouldn't go longer than 5 years. Some batteries will go longer and some shorter time. It's your choice.

I will be having it changed as soon as I get back east. My 2006 V6 Sonata original battery went 7.5 years with 225K miles before it died. This Genesis is much more electrical.

I am not arguing against replacing the battery. I would point out another difference between the Genesis and the Sonata. A battery in the trunk tends to last longer than a battery under the hood being exposed to engine heat and vibration.

I totally agree with your assessment along with the other people here who have more experience than me on this vehicle. I appreciate it.

My wife’s SUV gets a new battery every 5 years like clockwork because if I wait to 61 months, I get a phone call or I heading to buy a new one to replace it myself.

Update: My dealer Hyundai SH-8/49 battery finally died today, 85 months after replacement. Had a few blips with starting but finally quit, was getting ready to "jump" it from a family members vehicle but it started. Called my local shop and they had an Exide brand replacement battery, so it was swapped within a few minutes. I should be good for at least 60-72 months.

Mine lasted just short of 7 years...then failed to start just before I had to go to a colonoscopy. Replaced it with a store-bought Interstate something-or-other, and that only lasted 2 years. Charging system checked-out OK. This next one will be replaced at the 4 year mark.

I would agree with @Gunkk , hook up a battery tender for a couple days a few times a year. Seems to help even a half-worn-out battery last a bit longer, in my experience, especially if you don't drive the car very much...
