Introduction
18650 lithium ion batteries are lithium ion rechargeable batteries. They are 18mm in diameter and 65mm in length. 18650 batteries are used in many electronic devices such as laptops, cell phones, and power tools. 18650 batteries have many benefits over other types of batteries. Some of the 18650 lithium batteries have been modified to become 18650Tesla batteries which have a longer lifespan.
18650 lithium ion batteries offer a high energy density, meaning that they can store a lot of energy in a small space. The 18650 batteries also have a low self-discharge rate, meaning that they will not lose their charge as quickly as other types of batteries when not in use. A good thing with 18650 batteries is that they can also be recharged many times, making them very cost-effective in the long run.
Features of 18650 lithium ion batteries
Some of the physical and chemical features of 18650 lithium ion batteries include:
- 18650 batteries are 18mm in diameter and 65mm in length
- The lithium ion batteries have a cylindrical shape
- 18650 batteries are made of lithium ion cells
- The lithium batteries have a positive and negative terminal
- The batteries can be recharged many times
- 18650 lithium ion batteries have a high energy density
- The nominal voltage of 18650 batteries is 3.6 V
- 18650 batteries have a low self-discharge rate
- Minimum Discharge of 3V
- -18650 lithium ion Cell weight is approximately 48grammes
What is the mAH and C rating of 18650 li ion lithium batteries?
The most common terms that you may interact with quite often when buying lithium batteries are the mAH (milliampere-hour) and C rating. mAH defines how much charge the battery can hold (capacity) whereas the C Rating defines how fast it can release that charge.
For 18650 lithium batteries, a typical capacity is 2600mAh which means it should theoretically be able to output 2.6 Amps for one hour or 13 Amps for 5 minutes. But please note that these are theoretical values and in the real world, 18650 lithium ion batteries will never be able to output their maximum ratings for an extended period of time as it would damage the battery.
The C rating of 18650 batteries is often between 0.5C to 3C. What this means is that a 18650 battery with a C rating of 1C should theoretically be able to output its capacity (2600mAh) in one hour. But again, this is theoretical and you should never expect to get the full capacity from your 18650 battery in real-world usage.
Another important factor when choosing 18650 lithium ion batteries is the discharge current or how much current the 18650 battery can output safely without damaging itself. For 18650 batteries, the standard discharge current is 2.5 Amps but some 18650 batteries can go as high as 10 Amps.
As you can see, there are many factors to consider when choosing 18 650 batteries for your devices. In general, you want to choose 18 650 batteries with a high capacity (mAh rating), high discharge current (C Rating), and low self-discharge rate.
Uses of SPP 18650 Lithium Ion Batteries
18650 batteries are very versatile and can be used in a wide variety of devices. 18650 batteries are commonly used in:
- Laptops
- Power tools
-Power banks
18650 batteries are also becoming increasingly popular in Tesla cars. Tesla has been using 18650 batteries in their cars since the Model S was introduced in 2012. 18 650 batteries offer many benefits over other types of batteries, making them the most ideal choice for Tesla cars.
Protected 18650 lithium ion batteries vs Unprotected 18650 lithium batteries
18650 batteries come in two different types: protected and unprotected. Protected 18650 batteries have a built-in circuit that protects the battery from overcharging, over-discharging, and overheating. Unprotected 18650 batteries do not have this protection and can be more dangerous to use. They are also cheaper but we do not recommend their use.
It is always recommended to use protected 18 650 batteries, especially when using them in devices that draw a lot of power, such as laptops or power tools. Unprotected 18 650 batteries should only be used in devices that do not draw a lot of power and are not likely to overheat.
How times can the 18650 li ion batteries be charged?
18650 lithium ion batteries can be recharged many times. The number of times a 18650 battery can be recharged depends on the quality of the battery and how it is used. 18 650 batteries that are of high quality and are used properly can be recharged hundreds or even thousands of times. 18 650 batteries that are of lower quality or are not used properly can only be recharged a few dozen times before they need to be replaced.
When choosing 18650 lithium ion batteries, it is important to choose ones that have a high number of recharge cycles. This will save you money in the long run as you will not need to replace your batteries as often.
What should you look for when buying 18650 li ion batteries?
When buying 18 650 batteries, there are a few things you should look for:
- Capacity: The capacity of 18650 lithium ion batteries is measured in milliamp-hours (mAh). The higher the mAh rating, the longer the 18 650 battery will last before it needs to be recharged.
- Discharge current: The discharge current of 18 650 batteries is measured in amps (A). The higher the discharge current, the more power the 18 650 battery can provide.
- Recharge cycles: The number of recharge cycles is a measure of how long 18 650 batteries will last before they need to be replaced. The higher the number of recharge cycles, the longer 18650 lithium ion batteries will last.
- Price: 18 650 batteries vary in price depending on their capacity, discharge current, and the number of recharge cycles. 18 650 batteries with higher ratings will be more expensive but will last longer.
When choosing 18650 lithium ion batteries, it is important to consider all of these factors. 18 650 batteries that have a high capacity, high discharge current, and the high number of recharge cycles will be more expensive but will last longer and provide more power. 18 650 batteries that have a lower capacity, lower discharge current, and lower number of recharge cycles will be less expensive but will need to be replaced more often.
Conclusion
Our 18650 lithium ion batteries are a great choice for many devices. The 18650 batteries offer high capacity, high discharge current, and long life span. 18650 batteries are also relatively inexpensive and can be found at most electronic stores. When choosing 18650 batteries, it is important to consider all of the factors mentioned above. Choose the 18650 battery that best fits your needs and budget.
