If you've bought one lately, you know they aren't giving them away. I don't mean the kind for an EV car, just a normal ICE vehicle. They cost $150 and up, depending on what size and where bought. Mrs. Merkt's 2012 Hyundai battery had a 2017 case date on it. That's approx. seven years old. I did a static charge test on it, the voltage was getting down there but the battery wasn't giving any sign of imminent failure. But for a change, I decided not to try to get my last nickel's worth of current out of it before it fully crapped out. The previous replacement battery I'd bought at the Hyundai dealer for $125. It had a nice little folding carry handle on the top. The replacement that I bought this week was made exactly the same way, even down to the detail on the handle. The only difference was it had a NAPA sticker on it instead of Hyundai. Obviously made in the same factory. The latest one cost $180 plus tax.
Our son has a 2012 Lexus CT 200h, a little hybrid car. He bought it new, it has about 100K miles on it. That one has batteries for the electric motors, plus a "normal" battery for starting the IC engine. He hasn't had to replace the electric motor batteries, but of course the engine battery has been. It's been an excellent little car in terms of low operational cost. He follows the book on periodic maintenance but beyond that I don't think it's every needed any work. It was a breath of fresh air after his owning several German cars, all of which were a pain in the rump and costly to operate.
