How to distinguish the pros and cons of dry batteries

Dry batteries of the same brand and specifications can be weighed on an electronic scale. A good-quality battery is much heavier than a poor-quality battery. For example, the AA battery in the alkaline battery generally weighs about 23 grams, and the AA battery generally weighs about 11 grams. The No. 5 carbon battery weighs about 16 grams, and the alkaline battery is clearly heavier than the carbon battery in the hand. 2. Look at the high-priced dry batteries, which are generally alkaline batteries with relatively better quality. Don’t try to buy batteries cheaply from unlicensed and unlicensed vendors. These 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 batteries are much higher than carbon batteries in terms of capacity, shelf life, and reliability. If the dry battery is not properly solved 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.
