How to identify the quality of rechargeable batteries?

How to identify the quality of rechargeable batteries? 1. The most useful method is to directly test and compare the above important performance indicators. Since most of the above indicators must be measured with special instruments, it is not feasible for ordinary consumers. Of course, there are also some indirect methods that can be used for rough detection. For example, if two different batteries are used under the same conditions with the same electrical appliance (such as a walkman), the battery with a longer use time is naturally a product with a higher capacity. 2. Measure the weight and see the capacity. Generally speaking, the battery of the same process and the product with larger capacity must be heavier. For example, at the current level of industry technology, the AA model 2100mAh capacity nickel-metal hydride battery that can meet the standard in all aspects weighs more than 29 grams. 3. Look at the appearance of packaging Visual appearance is an important reference method to measure the quality of many products. For batteries, dense and smooth battery casings, clear printing, and excellent packaging material texture are the basis for quality assurance. Qualified battery products should be printed with trademarks, factory names, factory addresses, product categories and models, voltage identification, implementation standards, warning content, processing dates, etc. on the battery packaging. For dry batteries, the shelf life should also be indicated. Most inferior products will have unqualified items in the above appearance and packaging indicators.
