Battery Life

[pbtva01]

I just started my 7th year with my 2010 3.8 sedan and still have the original battery (which checks out OK). Any input on how long I can expect the battery to last? Car is garaged in Williamsburg, VA.

You are already living on borrowed time. Williamsburg is a very mild climate so if you are not doing a lot of driving with the A/C (when underhood temps are very hot) or not too much starting in very cold temps your battery will last longer. Garaging it in a heated space also helps a lot BUT average life of any car battery is something around 3 years.

My 2009 Genesis was assembled in Oct 2008, has about 55K miles on it, and still has original battery. Not having the Technology package helps a lot to extend battery life. I am not worried.

Original wiper blades also.

The battery will last until it dies. Some say five years is the high end of average. It's not going to wave a red flag at you and say "I'm dying." Hopefully, you have an AAA membership to rescue you while on a trip, or out at night on a dark street in Colonial Williamsburg. Changing the battery at the dealer will cost you less than $200. Doing it yourself will run about $125. If you don't have AAA coverage, add the cost of a tow to that.

I have a long way to go before worrying about a battery change, but the battery on my old Elantra lasted for 9 years in Chicagoland weather. It didn't die, but I noticed that the cranking was slightly slower in late December in 10 degree weather.
I tend to pay attention to things like that. If I notice a slower cranking on my Genesis, I'll replace the battery, no matter how long it takes.

I've only had my 2011 for a little while, but according to the service records, the battery was changed out in 2013. I usually get around 5 years from batteries in the Florida heat.

I normally swap out batteries every four years on a "preventive maintenance" basis. Maybe go a little longer with that big whomping agm battery in the trunk of my Genesis.

By the way, load testers are not all that pricey - try Harborfreight.

 

[PMCErnie]

I recently did a 4-year preventive maintenance battery change too. Why? Because the last three battery purchases I made were done off of an AAA truck at very inconvenient times. One incident was on a winter trip when we were 300 miles from home. By doing a preventive battery change you get the battery you want, at the price you want, and at the place and time of your choosing.

I'm in the same boat as Mark_888. my genny was built about the same time as his and had the original battery. Last November, the car had about 65k miles and was driving fine. Had a battery check tested since the winter was rolling in soon and the report showed it was running a little low. Figured, better safe than sorry. Went with a Bosche since the CA/CCA and reserve were all better than the OEM.

I have had my 2011 for about 5.25 years and have 102,000 miles with the original battery.

Replaced mine yesterday. I bought the car used, but the battery I replaced appeared to be the original. Car is a Genesis 4.6 2009 with 113,xxx miles on it.

I'm starting my 7th year also with my 2010 Sedan with Tech package. Just reached 49,000 miles.
Seriously thinking of changing it out soon just for the peace of mind. I don't want to be caught surprised somewhere and have to make a hasty decision on a replacement.

Any body have a recommendation for replacement?

 

[Mark_888]

After 7 1/2 years, I replaced the battery on my 2009 Genesis today as a precaution. I am pretty sure that my OEM battery was not an AGM, although maybe they used AGM on the tech package models with all the electronic systems. They might also use AGM on all the new Genesis models, not sure.

Since my OEM battery was not AGM, and from research I have done I found that flooded lead acid batteries are less susceptible to damage when deeply discharged (such as by leaving the trunk open, etc), therefore I went with a regular flooded lead acid (although it is sealed and maintenance free).

I went with an AutoCraft Gold from Advanced Auto Parts. I believe it is the same battery as sold by most other parts stores and made by Johnson Controls (with different plastic colors and different handles on top depending on the retailer). The list price was about $152, but I was able to use some internet discounts and a sale to get it for $119 (not including tax).

Advance Auto Parts normally installs it for free, but after the installer looked at the old battery connections, and then called someone to discuss, he decided he could not do it for fear that it takes special equipment (like a battery keeper) to avoid problems. He said they have had some cars like BMW's not able to start after doing a battery change. So I took the battery home and installed it myself because I was pretty sure that the Genesis did not have the same issue as the BMW. No real problems with the install, but several of the install videos I saw in YouTube missed one important point regarding the vent holes.

The battery has a vent hole on both the positive and negative side of the battery. On the Genesis the hole on the positive terminal side is used to connect to the vent tube. But that means the hole on the other side of the battery should be plugged up. There was a plug attached to the positive cover plate of the battery (which is normally discarded) that is used to plug the vent hole not used. I suspect that a lot people miss the fact that the other hole should be plugged (I almost missed that myself).

I am still using the original battery in my 2010. Only have a little less than 60,000 miles. I have never had a battery with this kind of life, Amazing!!

Every time I go to dealer for service they say the battery is fine.

Mark, what did you get as a replacement?

I bought an AutoCraft Gold from Advance Auto Parts. Size is 49/H8. It is a standard flooded cell battery (not AGM), but it is maintenance free.

I got a really good deal due to some discounts from Advance Auto Parts. I am pretty sure that the Walmart (Maxx Everstart) and Autozone (Duralast Gold) equivalents are the same battery made by Johnson Controls (but the plastic pieces on top look a little different). The Walmart battery (about $123) is probably a better deal if you can't get discounts from the others.

If you want an AGM battery, Autozone and Advance Auto Parts also sell them for about $25 more.

As I mentioned, I installed the battery myself. Here is a video that show how to do it:

However, there are two exceptions to the video I used:

• I did not slide out the battery (did not remove spare tire). Instead I removed the hold down flange on the front of the battery.
• I used the supplied plug to plug the vent hole not used (on the negative side of the battery). The vent tube goes into the other vent hole on the positive side.

My 2009 Genesis showed no sign of needing a new battery but I chose not to enter another winter with a now 8 year old battery. Replaced it yesterday. Cost $180 plus the dealer installation labor, but for peace of mind was money well spent,

 

[MADDMOE]

what type of battery did you get
