Our 2014 Spark OEM Delco battery lasted 3.5 years / 44,000 miles. Did the weird radio going dark, wipers turning on, hazards flashing dance when we tried to crank it one day. Most local Autozone did not carry one on their shelf, we had to search and drive a bit to find one in stock. The H4-DL cost $142 out the door with CA sales tax and state battery fee. The replacement battery we bought looked identical to the OEM down to the "Made in Korea" stamping on the plastic in the exact same location. Looks like the same factory cranked out all these and just put different stickers on top for brandin
