99 Kia Elan 1.8L
Just a single deep discharge event can kill a car battery, so although it may appear healthy showing fully charged, it might no be able to deliver the Cold Cranking Amps, so best you get it load tested.I've gotten 4 years each time. I'm on my 3rd battery. I always use the recommended size. With Covid this last 18 months and being retired, I had a flat battery at least 3 times due to lack of use (we ran the hybrid) and I'm not sure if that will shorten the life or not. As someone else posted, when they die, they die. I guess I should get some sort of emergency jumper for it. It's not really needed anymore as my plug-in hybrid gets tons more mileage, but it is like a new car; always garaged, always kept clean, no dents, only 80K, changed the timing belt at 60K, new Michelin all around, never smoked in, etc. I'm thinking I may give it to my grandson but the MPG isn't the greatest compared to more modern cars.
