How to Choose and Judge a Battery when Buying?

For our ordinary users, we don’t know much about the AA and AAA batteries commonly used at home, and we know almost nothing about the raw materials and processes of this battery. So when we go to buy, how to choose and how to judge the quality of the battery? Share a little opinion:

Alkaline batteries are usually better than carbon batteries. In terms of time, capacity, or safety, alkaline batteries are better than zinc carbon (heavy duty)batteries.

The weight of similar batteries can be weighed. This method is relatively simple. Although the weight has nothing to do with the distribution, if the weight is much different, the heavier one is definitely better. For example, alkaline AA batteries usually have 3 positive manganese rings inside. If one less, the battery will be lighter. The negative zinc draft will be lighter if the battery is missing. This method is not accurate, but it can be used as a reference for ordinary people.

For carbon batteries, you can press the battery with your fingers. If the battery has a strong hardness, it means that the zinc cylinder of the battery is thicker, the battery will be longer, and the leakage resistance will be better.

Look at the production date or shelf life, because the battery has self-discharge, although it is small, if it is a new battery, it is definitely better than a long storage time.

Of course, if you want to understand it in detail and from a professional point of view, you need to send it to a special testing organization for testing.

I hope a few tips will help you. For more knowledge, please visit Micropower Battery Website.
