How to avoid buying fake 18650 batteries

The popularity of this kind of batteries has also given the fake manufacturing companies a chance to manufacture fake batteries and package them in the very exact package as the original ones. This can give a buyer a very hard time to distinguish between the original 18650 battery and the fake one. However there are ways you can use to identify if the battery is original or not.

First thing you will have to do is to check through the details in accordance to the original battery, most fake manufacturers who make fake brand don’t include some very specific details about the batteries. The very minor information like the weight of the batteries is often ignored and that is the thing that gives you an indication that the battery is not original. Before you go to buy a battery on the shelf, you should first make sure that you have gotten all the information about the original battery so that you can make a comparison.

Another thing you can consider when identifying if the battery is original or fake is gauging by its price. There is a standard price of a battery that is from the manufacturer, however those people who manufacture fake batteries would want their batteries to sell really fast, for that reason they will lower the price even to almost a half the price of an original battery. If you meet such a scenario, you will realize immediately that the batteries being sold are not original ones.

The last thing you can check out is any kind of misspelling on the battery. If there will be a misspelling from the original manufacturing company, there will be a clear communication to the consumers about the error, if there is no communication and you meet a battery with a slightly different spelling just know they are fake batteries. Some fake manufacturers will just replace one letter from the original name and make you think that it was just error in spelling. You should be aware of such things.

To sum this up, you can appreciate that 18650 batteries have taken the centre stage in the use currently; almost every device that uses a rechargeable battery is using this king of battery. Their portability and durability are the reasons for that.
