How can you tell a fake 18650 battery?

When you're looking for a new 18650 battery, it's important to be able to spot a fake. After all, fake batteries can be dangerous - they may overheat, explode, or catch fire. Here are some tips on how to tell if a 18650 battery is fake: 

First and foremost, check the price. If it seems too good to be true, it probably is. Real 18650 batteries are not cheap, so if you see one that's being sold for significantly less than usual, it's likely a knock-off. 

Next, take a look at the label. A fake 18650 battery may have an incorrect voltage or capacity listed. The manufacturer's name may also be misspelled. Inspect the battery itself. A fake 18650 battery may have uneven or blurry printing, and the plastic casing may be thinner than usual.

Look for Authenticity Stickers. Usually, there will be a holographic authenticity sticker. Be sure to check for these signs before buying 18650 batteries to avoid being scammed.

If you're not sure whether a 18650 battery is fake or not, it's always best to err on the side of caution and buy from a reputable source. That way, you can be sure you're getting a high-quality, safe battery.

When it comes to 18650 batteries, it's important to know how to spot a fake. With these tips in mind, you can be sure you're getting a quality, safe product.

Is it better to have a higher mAh?

mAh stands for milliamp-hour, and it is a unit of measurement for electrical charge. The higher the mAh, the more electrical charge a battery can hold. 

However, that doesn't necessarily mean that a higher mAh battery will always last longer than a lower mAh battery. The performance of a battery also depends on other factors, such as its voltage, discharge rate, and self-discharge rate. 

In general, though, a higher mAH rating means that a battery can store more energy and will therefore last longer before needing to be recharged. So if you're looking for a new battery, it's generally best to choose one with a high mAh rating.


The 18650 battery is a great option for those looking for a reliable and long-lasting battery. There are many different brands and types of 18650 batteries on the market, so it is important to do your research before purchasing one. We hope that our list of the best 18650 batteries will help you make an informed decision when choosing the right battery for your needs. Thank you for reading!
