How to distinguish between good and bad batteries

In everyday life, people use remote controls, radios, blood pressure devices, flashlights, and electric toys to install several dry batteries. Some consumers will find that some batteries can not be used for a short period of time. They must have bought inferior or counterfeit products. So how do you tell the difference between a good battery and a bad one?

One weight.

Dry batteries of the same brand and specifications can be weighed on an electronic scale. Good batteries are much heavier than poor batteries. For example, Changhong alkaline 5 battery weighs more than 23 grams, and inferior or counterfeit products generally do not exceed 16 grams.

Two, look at the price.

High-cost dry batteries are generally alkaline batteries and have relatively better quality. Do not covet the purchase of batteries at unlicensed vendors. These batteries not only have a short time to use, but also have the potential to leak fluids and pollute the environment.

Three check the appearance

Good dry batteries will be marked on the packaging with trademarks, manufacturers, battery models, nominal voltage, battery polarity, production date, shelf life, and implementation standard numbers, and the workmanship is exquisite, clean and clean, and there is no leakage. When purchasing, you can also see whether the merchandise is marked with the words "mercury-free", "0 % Mercury" and "mercury-free".

In general, through the above three steps, the quality of the battery will clearly appear before your eyes.
