Why Buy the Best 18650 Battery for Flashlight?

The reason 18650 batteries are so striking because they possess the power of three regular batteries. So you do not have to worry about what to use during blackouts, lighting the tent at night, search parties, and trekking in the evening.

A good flashlight is only dependable because of the batteries it uses. Even a fancy torch will only be as good as the batteries that keep it running.

You must be wondering what makes these batteries so special. Don’t worry because this article focuses on the essential information about these batteries.

The 18650 batteries get their name from their measurements 18mm X 65mm. They have the same shape as the AA size batteries but are slightly large. Additionally, they are lithium-ion batteries which make them rechargeable.

Here are some qualities that come with the 18650 batteries:

You Can Recharge Them

18650 batteries are not that kind of batteries you throw after using. So you do not have to worry about polluting the environment and spending a lot on batteries for your torch. These batteries will last you longer because of their ability to recharge. They retain power for at least 30 hours after a full charge which is 3 times more compared to regular batteries.

Another unique aspect about 18650 is that they do not need to be completely discharged to be charged like other rechargeable batteries.

They are Lighter

If you compare the weight of 18650 batteries with others of the same size you will be surprised how light they are. This battery is lighter because it is made of lithium which can hold 150 watt-hours electricity in a kilogram opposed to the lead-acid battery which holds 25 watt-hours in a kilogram.

Flat Top Versus Button Top

When you start using 18650 batteries you will notice that there are those with button tops while others have flat tops. Actually, this does not mean a thing or make any difference. However, it depends on your flashlight structure. Torches with springs or those that need the batteries to touch the bulb will need batteries that can tightly fit – which button batteries can provide.

This will need you to be cautious when purchasing batteries. You should know the battery configuration that is ideal for your flashlight. If you have no idea how to check this ask the salesperson what will work well with your torch.


How to Buy the Best 18650 Battery for Flashlight:

Three tips that need to be considered when choosing batteries include the capacity of the battery, cycle life, and voltage.

Battery Capacity

The capacity of a battery is its total power storage. This is presented in mAH also known as milliamps per hour. The 18650 falls between 2000mAH to 3500mAH. The bigger the number the more storage capacity the battery has. This then means that your batteries will last longer and will produce bright light when the mAH is high.

The Battery Voltage

18650 batteries have voltages between 2.5V to 4.2V (V standing for volts). For the sake of understanding, voltage is the amount of pressure the battery uses to transfer electricity to the appliance in use. This means that higher voltages will discharge power more.

Different devices will need different voltages. A torch will need less voltage compared to a laptop.

The Life Cycle of Batteries

Every manufacturer will brag to produce the longer battery cycle life. The cycle life of the battery is usually written in the specifications. This is the number of cycles you will use the battery until it declines in its value or health. A single cycle depends upon fully charging the battery and discharging it to near empty.

In Conclusion

EBL 18650 6 pack batteries is our choice of the best 18650 battery for flashlight. It is the brightest deal you can get as they cost below 20 bucks. Its incredible features like slow self discharge when not in use and the fact that it can be charged over 1000 times with absolutely no memory effect make them a perfect choice.

Just to recap -the crucial features 18650 batteries need to possess include – a power capacity that is high, the ability to charge quickly, the ability to fit into devices flawlessly, lack a memory effect, hold its charge for the expected time, and have a protection circuit.
