The 18650 battery
Here we will learn what a 18650 rechargeable battery really is. The 18650 battery is described by its size because it measures 18mm by 65mm. the 18650 is actually regarded as the new standard for rechargeable and replaceable batteries.
These batteries have the standard performance of a typical lithium-ion battery. In addition to that, they have a capacity of 1800mAh to 3500mAh and an output of 3.7 volts. These features have made them perfect for cameras, flashlights and laptops among other electronics.
Here’s one thing that you should know; these batteries have the best performance when compared with any other rechargeable battery available on the market today.
Specifications of the 18650 Rechargeable Battery
The 18650 rechargeable battery might be having the exact same looks like the AA batteries, but they are totally different. Here are the specifications of the 18650 rechargeable battery that make them different from others.
· Shape – the 18650 battery has flat, thin sheets of metals that make up the cells. These cells are stacked and rolled tightly to form a roll, giving the battery its shape. In between the layers, there are lithium ions that move from one direction to the other during charging and discharging. The rolled sheets of metal are packed into a cylinder shape.
· Size – the 18650 battery measures 18mm by 65mm. they are slightly larger than the AA batteries.
The Best 18650 Rechargeable Battery For Different Applications
When it comes to buying the 18650 rechargeable battery you want to make sure you buy the best. You do not want to get frustrated later for buying the wrong type of battery that cannot serve your needs.
The 18650 batteries offer the best performance among all consumer-grade rechargeable batteries. They cannot get easily damaged from charging before they are fully discharged, unlike the old nickel-cadmium cells. However, these batteries degrade at about the same rate as the smartphone battery.
In order to get the best battery, you have to consider what you are going to use it for. But here you will learn how to choose the right 18650 rechargeable battery. Here are some of the factors to consider when buying the 18650 rechargeable batteries.
CDR
CDR is actually the continuous discharge rate of the battery. This is one of the most important factors to examine when you are shopping for 18650 batteries. CDR is measured in amps (A). It is actually the rate of current that can be pulled from the battery without overheating. In order to find the right battery, you will need to match the CDR of the battery with the power draw of your device. If you get it wrong, you are going to choose 18650 battery whose cells will become hot when your device is drawing current. Overheating causes damage to the cells and reduces the lifespan of the battery. In addition to that, overheating can lead to a battery leak, explosion and even damage to your devices.
However, there is a direct relationship between the CDR (A) and the capacity of the battery (mAh). If a battery has a high capacity, then the CDR will be low. This means that if your devices draw less power, the higher capacity cells would be perfect for them. Devices that draw higher power would require lower-capacity cells in order to draw more current without overheating.
Voltage
Voltage is actually what controls the flow of energy in your device. If there is a high voltage, current moves faster and that provides more power. However, voltage might lead to overheating. In some situations, you might find your battery power draining quicker than you expected. This is why it is important to read the manual of the product that you’re using to see what the recommended voltage is.
In most 18650 batteries you will find ratings of 3.6 or 3.7 volts. The difference between them is actually negligible.
Battery Life
When you are shopping for 18650 rechargeable batteries, of course, you want to buy a battery that lasts. Battery life is actually one of the most important things that people look for when buying a battery. The loner the battery life, the longer it will serve you. Therefore, you need to go for those batteries that have a long–lasting charge and a longer shelf life as well.
Compatibility
There are different types of 18650 rechargeable batteries and they are not all compatible with all devices. Therefore, you need to be sure of what your device needs before you go out shopping. If you don’t verify that, you might end up buying batteries that you will never use.
Safety
Safety is a great concern when it comes to all batteries. To ensure safety, you need to choose a battery that features the right voltage for your needs. Also, you want to make sure that the casings of the batteries are not weak. Do not buy batteries with compromised outer casings because they would not be safe to operate.
However, it is important to note that lithium-ion batteries are now safer than before. More improvements have happened over the years and there are very few cases of people having trouble with them.
Protected Vs. Unprotected Batteries
18650 rechargeable batteries are available in two different forms; protected and unprotected cells. The protected batteries feature a small electronic circuit integrated into the battery design. The circuit is located on one end of the battery and it is not easy to distinguish it from the cell itself.
The purpose of the circuit is to protect the battery against dangers of excessive charging and discharging, extreme temperatures and short-circuiting. This ensures that you are protected from leaking or explosion. When the pressure rises too high, a valve disables the cell completely in many protected batteries.
Unprotected batteries, on the other hand, do not have this circuitry. For that matter, they will usually cost less than the protected batteries. However, they are more prone to the dangers that such circuitry is designed to avoid. Therefore, if you choose to settle on the unprotected batteries, you need to take a little more care with them.
You need to pay more attention to the discharge rating (CDR) so that there is no overheating due to excessive power drawing. The contacts must always be covered in a plastic case to prevent short-circuiting in your pocket or bag. Also, you need to make sure the batteries are not left charging for too long.
Flat Top Vs. Button Top
The 18650 rechargeable batteries are available in two variations in size: flat top and button top. These terms basically relate to the contacts on the battery. Batteries with a button top have a slight protrusion, while those with a flat top remain perfectly flush.
This matters because size is crucial when you are looking for a 18650 battery for your device. They introduce a difference between a battery that fits and one that doesn’t. To get the right one, you need to look at the batteries that your device came with or check the manual.
Cost Trend of The Best 18650 Rechargeable Battery
The lithium-ion battery prices have declined over the years. Today, the prices are lower than ever. The increasing production capacity is expected to stabilize the prices of the 18650 lithium battery raw materials. However, the improvement of energy, labour costs and transportation costs play a significant role in lowering the cost of 18650 battery.
Conclusion
Buying 18650 rechargeable battery from a reputable buyer is a great way to be sure you’re getting what you have paid for. A great 18650 lithium battery will meet your needs and serve you for a long time.
