What are the methods to distinguish the pros and cons of dry batteries?

How to distinguish the pros and cons of dry batteries 1. Weigh dry batteries of the same brand and specifications on an electronic scale. Good quality batteries are much heavier than poor quality batteries. For example, the No. 5 battery in the alkaline storage battery generally weighs about 23 grams, and the No. 7 battery generally weighs about 11 grams. The carbon storage battery of No. 5 weighs about 16 grams, and the alkaline storage battery in the hand is obviously heavier than the carbon storage battery. 2. Look at the high-priced dry batteries, which are generally alkaline batteries with relatively better quality. Don't be greedy to buy storage batteries from unlicensed and unlicensed vendors. These storage batteries are not only short-lived, but also have potential risks of leakage and environmental pollution. 3. Check the dry battery with good appearance. The package will indicate the trademark, manufacturer, battery model, nominal voltage, battery polarity, processing date, shelf life, implementation standard number, and the workmanship is exquisite, neat and clean, and there is no leakage. When purchasing, you can also check whether the goods are marked with no mercury, 0% mercury, and no mercury added. 4. Look at the logo. Dry batteries are divided into alkaline and carbon. Alkaline dry batteries are marked with alkaline or ALKALINE, and carbon dry batteries are marked with carbon. Alkaline storage batteries are much higher than carbon storage batteries in terms of capacity, shelf life, and reliability. If the dry battery is not properly handled after use, it will cause irreversible pollution to the environment. Therefore, after using the dry battery, you must recycle the battery instead of losing it everywhere. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
