    What is the proper battery replacement for a 2019 Kia Optima FE ? My car stopped working the other day and had AAA come out to help diagnose this issue and they said i have a bad battery. Bought this car less than 6 months ago and have always brought it in for maintenance when it is due. Also...

    Long story short, I made the stupid decision to put a car battery from one of our other cars into our Optima to test if it needed a new battery (old one wasn't holding a charge, should have just replaced it lol). Immediately after connecting the new battery, the car honked and I saw the fuse by...

    My brother has a 2015 Kia, turbo with a push button starter. His smart key said low battery, so he replaced the battery. It still shows low battery even with the new battery?? Any ideas?

    Dealer says my regular 12V battery needs to be replaced. They want 500 for it. I think they are nutz.. Does anyone know what the deal is , and is there an acceptable aftermarket battery.

    Very strange. Dealer said that "something" in my battery caused my starter to fail (be destroyed). They replaced the starter (still didn't start), then replaced the battery and everything worked! Strange! Am I being bamboozled?

    Should you remove the battery terminals when charging the battery? If so, is there a security code to put into the radio after disconnecting the battery?

    Hi all, My '11 Optima Hybrid only has 61k miles on it, 35k of which is the last almost 6 years. I've been working from home for 5 years hence the low miles, as it only really gets driven infrequently around town or to the airport when needed. I'm now switching jobs and will be driving about 30...
  11. 4th Generation Optima (2016 - 2020)
    Has anyone had the pleasure of having to replace their battery yet? Well mine died this morning. Went to start it and it did some really strange things; dash lit up like a Christmas tree, headlights started flashing, and there was a crazy loud clicking noise coming from under the hood. Jumped...

    Yesterday while I was stopped at a red light. All of a sudden, I get a dash warning. It displayed HEV in a triangle, then said to shift into park and turn off vehicle and check hybrid system. I shifted into park and turned the car off. I tried starting it back up to no avail. Kept saying...

    Been reading a few battery threads but I didn't see the topic discussed. My OE battery on my 2015 Optima EX is dying. I got 4 years out of it so based on what I've read here I should be relatively happy with it. The battery is an H6 AGM. My local wallyworld doesn't have the H6 AGM battery in...

    The car is at approx 72,000 miles. I have seen a couple others facing similar issues but not much on what the final issue was or how it got fixed. Up until this point I have loved the car. On 3 separate occasions the hybrid battery has completely discharged at highway speeds causing the car...
  17. 3rd Generation Optima (2011 - 2015)
    The last 2 days my car wouldn't start in the morning, been around 40 degrees or so,but probably about 30 this morning. After 10mins of pushing buttons it finally registered and got it going. Not sure if its the car, the fob, or just the battery. I had even tried my backup fob but it was even...

    Hello, I recently had my battery die a couple of days ago. I took in my battery to get it tested and it was in fact a dead battery. So then I had replaced it with a new battery, connected everything back together and everything worked fine (driving around town, the freeway). But then a couple of...

    Going to be replacing my 3 year old battery today, 2015 Optima EX 2.4L, is there a 'radio code' I'll have to know to get the radio to work again after the replacement? If so, where can I find it? I checked the KIA Owners website where I have my car registered, didn't see it there... My Honda...
  20. 3rd Generation Optima (2011 - 2015)
    Recently, I noticed that the battery in my 2015 EX (2.4L) struggled a bit with cold starts. Got the multimeter out and did some voltage measurements. At no load, the battery measured 12.4v which is acceptable. With the headlights on, however, the voltage dropped to 10.5v which is not...
