Where to Buy 18650 Batteries Near Me?

The 18650 is a kind of li-ion rechargeable battery. portable devices have been revolutionized via lithium-ion batteries. it is all about smartphones, cameras, medical monitors, fitness devices and flashlights wherein 18650 batteries are used.

Cells, like the 18650, once reserved for tool producers, have discovered their manner into customer hands as battery technology has matured. these new lithium cells, but, have no longer been standardized as the rechargeable as you’ll find inside theSupermarket.

You should make certain which you buy the right 18650 battery for your tool and recognize a way to keep away from fake batteries if you want to safe your devices and batteries.

Price cost of 18650 Battery?

An improvement of 8 percent in the capacity of li-ion batteries is seen year after year. This is a slow but exponential growth, compounded. Improvement is linear in every battery chemistry. In order to allow exponential growth, new generations of batteries with new chemical paradigms (all can be lithium-ion, with different chemical balances) are needed. It is expected that this growth will continue for at least 25 years where a physical limit can be reached to the amount of energy we can put in a material (~1 eV per atom).

More than 40% of the batteries in the world are lithium ion. The 18650 battery is one of the most widely produced types of lithium ion batteries as it is used in smartphones, power tools, robots, electric vehicles, vaporizers, solar grids, and almost any application you might think of needing to more effectively store electrical energy. The manufacturing cost of an 18650 battery has fallen from $10 for ~1500mAh (twenty years ago) to $2 for ~3000mAh (today). As the cost per kilowatt hour continues to drop, the technology-fueling demand and economies of scale-can be used by new applications.

 

How Do You Find A Good 18650 Battery Supplier?

Ow a days it is very important to buy the batteries from a well-known vendor as there are so many agents in the market who are selling fake batteries by tagging the name of brand that is why you have to be aware of the fakes, like any branded product. Many vendors often buy cheap cells, rewrap them as brands of name, and sell them as genuine items through Amazon or eBay which is not only harmful for your device but also for your health as it can explode or can be very dangerous.

This is not only a waste of your money, it is potentially dangerous. If you buy a battery for a high powered device that believes it has an adequately safe CDR, when the battery turns out to have a completely different rating, you could injure yourself or damage your device.

Scammers of batteries are good at what they are doing. It’s incredibly hard to tell apart a true battery and a fake. From packaging, branding, online listings as they look like the actual deal. The only way from a genuine battery you can tell a fake is by weight.

Most brands have made available somewhere the weight of their genuine batteries. All batteries you buy online should be cross referenced with the specification of the manufacturer. Even spelling errors do not indicate a fake, as a genuine manufacturer had to point out through an update to Facebook.

It’s better to search through the internet for its name to check a specific cell, followed by “datasheet,” which lists the battery weight, capacity and total CDR and then purchase a battery.

How to get a good quality 18650 Battery?

Steps to select 18650 batteries

• Purchasing good quality cells is probably the most important thing. Cells manufactured by Sanyo / Panasonic, LG, Sony, and Samsung are all of high quality and have ratings friendly capabilities. In addition, 18650s of good quality are safer than cells of cheaper, lower quality.
• Make sure you have ample current capability for your use in the cells you purchase. For example, the highest capacity cells (Sanyo NCR18650GA, LG MJ1, and Samsung 35E) are relatively low current cells (maximum continuous 10A) and are unsafe for high current use. Make sure that the current capacity is high enough for your use. On the other hand, for lower drawing applications, high-current CAN cells are used. These even have some advantages over lower draw cells, such as better voltage management and the ability to accept a faster charge. Capacity is going to be lower, but it’s less than that.
• Make sure that the voltage is appropriate. Most of the 18650s were rated at 4.2 V. But some charge 4.35 V, while others charge only 3.6 V ( LiFePO4 ). It is ok for 4.35 V cells to be charged to 4.2 V and used in 4.2 V applications. But it’s going to reduce  the capacity. However, it is best to avoid charging 4.2 V batteries to 4.35 V. Also, remember that some devices designed for 4.2 V batteries may be impaired by a 4.35 V battery charged to the maximum 4.35 volts. Furthermore, avoid using LiFePO4 for applications requiring 4.2 V or 4.35 V charging.
• Purchase from reputable retailers batteries. Fakes are common when it comes to naming brand cells. Buying from a reputable vendor reduces the likelihood of fake cells.

What is the Difference Between “Protected” and “Unprotected” 18650 Batteries
As you know, 18650 Lithium-Ion batteries are very powerful. Because of that, you should be aware of the safe handling of them. Don’t look just at the price of the battery. With 18650 batteries, you truly “get what you pay for.” If money is tight, it’s best to purchase a lesser-priced flashlight rather than cutting corners on an 18650 battery.

18650 Batteries with PCB protection

Protected Lithium-Ion (Li-ion) batteries have a small electronic circuit integrated into the cell packaging. This circuit protects the battery against common dangers, such as overcharge, over discharge, short circuit/over current, and temperature. Protected batteries are safer to use in your devices. Protected batteries are less like to ignite and cause personal or property damage.

Most protected batteries have these components:

PTC: Protect against over heating and indirectly over current. Will automatically reset.
CID or Pressure Valve: Will disable the cell permanently if the pressure is too high in the cell (Can be due to over charge).
PCB: Will protect against over discharge, over charge, and over current, depending on design. The PCB will reset automatically or when placed in a charger.

The following images show you examples of the components of a safe, well-designed protected 18650 battery.

18650 Batteries without PCB

Unprotected batteries do not have this electronic circuit in the cell packaging. Because of this, they can have more capacity and current capability than a protected cell. However, there is always a danger of over heating, short circuiting, or over discharging. Unprotected batteries are also much lower in price.

IN SUMMARY: Users must decide whether they prefer protected cells which are safer to operate or accept the bigger responsibility and danger associated with unprotected cells. Most battery specialists will recommend you always use protected batteries.
