How Long Should the Manufacturing Date of a New Battery Not Exceed?
2 Answers
Different quality batteries have different shelf lives, with high-end ones lasting up to 5 years. Below is relevant information about batteries: Introduction: A battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable, achieving recharging through reversible chemical reactions, typically referring to lead-acid batteries, which are a type of secondary battery. Working Principle: During charging, external electrical energy is used to regenerate the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output, such as the commonly used mobile phone batteries in daily life. Classification: Commonly used automotive batteries are mainly divided into three categories: conventional batteries, dry-charged batteries, and maintenance-free batteries.
I often deal with car maintenance topics, and it's best to discuss that the manufacturing date of a new battery should not exceed 6 months. I remember last year when I helped a neighbor replace their battery, I didn't pay attention to the date and bought one that was 8 months old, which failed after just half a year, causing starting difficulties. Lead-acid batteries self-discharge even when not in use, and over time, the internal chemicals degrade, leading to unstable voltage. Typically, date labels follow formats like B24, representing February 2024—choosing those is a safe bet. Additionally, storage conditions are crucial; high temperatures or humidity can accelerate deterioration, so even in a garage, choose a well-ventilated spot. New car owners often overlook this, trying to save money but ending up with more hassle. It's advisable to always check the manufacturing date on the battery packaging before purchasing to avoid travel delays and extra repair costs.
