18650 is the size classification of lithium- ion batteries and the ‘18650’ comes from their size. The diameter of these batteries are 18mm and height is 65mm. They are a little bit bigger than AA batteries but the shape is the same.

The first thing you need to consider is how long the battery will last. Because battery with long life will allow you to use the device smoothly for a long time. That means if the battery you’re using has long life guaranty, you don’t need to be worried about going out of light when you’re at camping or tracking with your flashlight or any other device.

2. Voltage:

Another important thing you need to consider for buying your 18650 batteries is its voltage. The voltage of the battery controls the flow of energy in your device.

If the battery has a higher voltage, the current will be faster which will provide any of your devices with more power.

But the drawback of higher voltage is the battery get overheat quickly and drain the power of the battery fast.

But if you should check the manual of your device and check the recommended voltage and use according to this you can avoid this problem.

This batteries are one of the most recommended batteries and compatible to flashlights of leading brands. Its capacity is proven to be 9800mAH as advertised. Besides, its high voltage makes it perfect to use in demanding applications. 

Its safety mechanism is a state of the art. It disconnects automatically in case of high voltage, high current, over charge or discharge and overheating. Batteries have 5 years of storage life and more than 500 charge cycles. Once you install this battery, you will not need another one for at least a couple of years.

These batteries from M&A BD Electronics come with impressive 2900mAH capacity to deliver tremendous power to the host device. Despite of the high capacity, it gets charged comparatively quicker than expected. It is available in a reasonable price too. 

The downside is, the manufacturer did not put any protective insulation in it for some obvious reasons. Due to the  lack of protective circuit, there is risk of overheating. But I did not get any complain about overheating so far. Some users have complained over the cover peeling off within a couple of months use. That is not a big issue, nor it will affect its performance. But this is somewhat disappointing for a rechargeable battery.

However, I will recommend this battery only in devices with built in protection circuit. Besides, it can only be used in 3.7 v devices. To power up expensive and more demanding gadgets, it will be wise to look for safer options.

Things We Liked

  • High capacity;
  • Holds charge for long time;
  • Long lasting. 

Things We Didn’t Like

  • No Noticeable Cons;

Here you get high quality batteries from UltraFire. This economic deal is somewhat risky due to China made dupes of these excellent batteries. So, be sure before buying. This shows 2200 mAh capacity in tester whereas the real batteries are 2200mAh capacity. 

These batteries are bare, free of any protective units. Hence, only can be used in devices and flashlights which has built-in protection system. This is the only drawback of these beauties. Besides, these comes right out of industry without any decent cover ups.

The brand name UltraFire represents authenticity and reliability. These items are no different; for reliable use for years for your flashlight or vapes, this unit can be a good choice.

Things We Liked

  • High quality;
  • Compatible to any device that runs on 18650;

From the title you know, these are 18650 Rechargeable Battery 3.7v Li-ion 6000mAh Batteries by Shine Tool. Its specs suffice the requirements you need to fire up your electric tools, toys, LED flashlights, torch etc. The matter I liked about this pack is, it comes in hard storage case. Personally I prefer purchasing tools which comes in cases for protection and storage purpose.

Besides, very few manufacturers mention in their advertisement about the lacking performance of their devices. According to the advertisement, these batteries form Shine Tool are more likely to drop its capacity to 60% after 250 charge cycles. So, you will know what performance to expect when.

Like other lithium-ion 18650 batteries of this list this pair also comes without any protection unit. The budget friendly price may seem more appealing to some who does not need this pair for long term demanding applications.

Things We Liked

  • Suitable for your electric tools, toys, LED flashlights, torch etc;
  • Mid range capacity;
  • Comes with storage case;
  • Budget friendly price. 

Things We Didn’t Like

  • Capacity degrades after 250 charge cycles.

The benefit of high drain batteries are, these are less likely overheat while charging and discharging and are suitable for demanding applications where high amperage is required.

These batteries from M&A BD Electronics are great to use in electric tools, toys, LED flashlights, torch and other high drain devices. These are available in an affordable price range. As these are high drain batteries, they charge faster. 

To fit this pair in an affordable range, quality is compromised a little. Its capacity will be reducing over each charge; will be half after 250 charge cycles. Its charge holding capacity will be reducing simultaneously. Some users complained about overheating when it ages, but overall this unit is just fine when this is new.

Things We Liked

  • Affordable;
  • For high drain devices;
  • Comes with plastic case.

Things We Didn’t Like

  • Performance degrades over time;
  • May overheat.
