On my car the voltage shrink to 12.3-12.4 after 3-4 days (from fully charge). A week without driving it will be around 12.25-12.35. I suspect anti-theft system takes more energy than regular car. Or maybe my car has phantom drain issue/I forget to turn off something.Anyone else have problems with keeping a good charge on this replacement battery? I bought it a year ago, and today I noticed it's only at 11.6 volts. Also had check charging system screen pop up today, and car wouldn't start.
Thanks for sharing that, I must have a bad battery, I drove it for 4 hours the other day and the highest my charge got was 11.8 volts, I bought it last year. Good thing it has a 3 year warranty.On my car the voltage shrink to 12.3-12.4 after 3-4 days (from fully charge). A week without driving it will be around 12.25-12.35.

Yeah that's definitely a bad battery. It should top off at 12.6-12.7v after one hour highway drive.Thanks for sharing that, I must have a bad battery, I drove it for 4 hours the other day and the highest my charge got was 11.8 volts, I bought it last year. Good thing it has a 3 year warranty.
I just changed my 2013 Hyundai Sonata Hybrid battery 124R, 78 amps, 3 yr warranty at the Hyundai Dealer for $180. ($210 - $30 coupon). Walmart had ran out of 124R MAXX battery, 110 amp, w/5 yrs warranty for $88. The only difference is the Hybrid 12v battery has a vent to prevent acid corrosion in the trunk.My 2012 Sonata Hybrid is going on 6 years old (purchased Jan 2012) Can you believe im still using the original 12v battery!
The heat down here in South FLorida is hard on batteries and I always get a new one after 4 years. Now that my OEM battery is nearing 6 years old I knew I had to replace it or risk getting stuck. ( the car still starts instantly, im curious how long the original battery would last if I kept it)
Side note: I discovered the reason the 12v battery lasted as long as it does. It doesnt actually start the car. The 12v only turns on the cars computer and runs the accessories when in ACC MODE.
The 270v hybrid battery actually starts the car.
Anyways, after a lot of searching on the intern-webzzz and this forum, the best I could find are "similar" batteries or a battery that needed a modified battery box to hold it stable.
I did a lot of searching at auto parts stores and again, few would show as "THIS FITS YOUR CAR" and the couple that did were $200+
No way im going to pay Hyundai $329 for a battery! YES! They want $329 for an OEM 12v battery! INSANITY!
I kept searching then discovered ADVANCE AUTO PARTS has one that says it will fit , is vented and its only $155.
Took a chance and ordered it and it not only fits , its the identical battery to my OEM battery in every way and even made in South Korea. ( the same 600CCA too)
Battery was only $155, and FREE SHIPPING! I found a code RETMENOT20 which saved me another $31 ! The core charge was $22 which I think you can get some core money back by returning to an auto parts store (im keeping mine to run a livewell pump) So even with tax and core charge I only paid $157 right to my door! O yeah, I recieved the battery 2 days after I ordered it! THANK YOU ADVANCE AUTO!
Here is the link. Im attaching a photo showing the battery installed. It even has the hole to attach the VENT HOSE!

I just bought and installed this too. It's also made in Korea, had a 2/21 label, and physically identical to AA's, including vent for hose. Replaced battery was labeled Delkor.Have had my 2011 Hyundai Sonata Hybrid for 5 years now. In Dec 2020 noticed that the charge on my battery was low. For example I would notice the cabin lights looked dim and a couple times the car would not start for a few tries. All symptoms of your standard car battery going bad in cold weather (well cold for Texas). Once the car started and the hybrid system took over the car would run fine.
I used earlier posts on this forum to find a replacement battery specs. Unfortunately neither Advance Auto parts or Autozone had the right batteries available. I managed to find this.

Has worked great with no problems for a month. Hope this helps.
Can't speak for that particular battery, but the H6R I got from Autozone has a hole for vent tube to plug in.Hello, I'm new here. I am thinking of replacing my 12v battery in my 2016 Kia Optima ( I know its not a Hyundai "per se") and want to thank this forum for helping me find a battery. I was quoted from the dealer $383 plus $70 labor to install. I am thinking of going with the "Interstate MTP-H6R". Their website even lists it as "Hybrid Auxiliary Battery".
Here is the question: Does this Interstate MTP-H6R battery have an allowance for the VENT TUBE ???? Thanks in advance.

Your original battery looks like it was replaced with a 2/17 model at some point?Thank you so much this post was very helpful for me, I purchased my Hybrid Hyundai Sonata 2012 brand new and just now the battery completely died, me being the original firts owner with an original battery which lasted 10 years WOW!!!
I went to Advance auto parts as you suggested, they had it in stock and they installed it for free in less than 15 minutes, now the price is $180 plus tax plus $22 core charge, but since they kept my old one I wasn't charged the extra cost, $195 total, the dealer price was $289 plus tax and it wasn't going to be done on the spot, 2 to 3 days they said, since it's the only car I have I couldn't afford to be without a car, autozone was going to still order it for me and they do not install it, same price though $180, I had to drive 30 minutes to get to Advance auto parts but it was worth the drive, thanks again View attachment 464583
