The production date of car batteries is generally printed on the surface of the battery and is represented by a series of numbers. The number is composed of a series of numbers and letters. Because the battery is a three-pack of wearing parts, and different brands of batteries, the warranty period is not the same, most of them are 1 year or 20,000 kilometers, as indicated in the specific battery manual.

Therefore, we need to purchase batteries through formal channels, because there are some small factories on the market that recycle old batteries. The production date of such batteries is basically unreliable, quality is not guaranteed, and there are certain safety risks.
