People are aware that products like food and medicine have expiration dates, but did you know that batteries also have an expiration date? Today, electronic and digital products are becoming indispensable assistants in people's lives, work, and entertainment. However, many consumers are not well-informed about how to choose the right power battery for electronic devices. For this reason, experts from Procter & Gamble’s Duracell brand remind consumers that batteries have an expiration date. Consumers should check the production date carefully when purchasing and using batteries, as expired batteries may result in weak or even no power.
I always thought batteries were like home appliances, as long as they were unopened, they were new. I didn't realize they had an expiration date,’ said Mr. Yang. In addition, many citizens have reported that many malls and supermarkets offer promotional deals on large packs of batteries, often in sets of 8 or 12. These sets are usually covered by uniform promotional packaging, which makes it difficult to identify the production date, leading consumers to unintentionally overlook checking the date.
Generally speaking, the shelf life of ordinary alkaline batteries is 3 years, while branded batteries have a longer shelf life. Duracell, known for its superior quality, has an effective lifespan of up to 7 years. Therefore, consumers should choose branded batteries and also check the production date and expiration date when purchasing, aiming to buy the most recently manufactured batteries,’ explained an expert from the Duracell brand. Batteries work through a chemical reaction between the positive and negative terminals. Because the materials in these terminals contain trace amounts of impurities, a constant chemical reaction occurs, consuming active substances. As the battery is stored for a long time, the active substances decrease, causing the battery's capacity to drop, which results in the weak or no power that we sometimes experience.
Duracell, a globally renowned symbol of long-lasting power, has a battery lifespan of up to 7 years. Founded in 1964 in the United States, Duracell has provided high-quality products and long-lasting power to consumers worldwide for over half a century. It also promotes a healthy and active lifestyle, winning the unanimous favor of consumers around the globe.
