What does “18650 Battery” mean?

Excellent choice for Prototype with limited battery capacity


The 18650 lithium ion battery was the forerunner of Lithium Ion batteries, a standard lithium ion model developed by Sony to save money. We often say “18650 lithium ion battery” , in fact, it is the size of the battery named Lithium Battery, which 18 denoted diameter of 18 mm, 65 denoted length of 65 mm, 0 denoted cylindrical battery. The No. 5 battery, which is more commonly used in homes, is 14500, or 14mm in diameter and 50mm in length.

In short, 18650 is the size of the lithium ion battery. According to the battery type, the common 18650 battery is divided into lithium-ion battery and lithium iron phosphate battery, the former is more commonly used in the market.

What are the advantages of the 18650 lithium ion battery?

lithium ion battery 18650 high capacity, it is undoubtedly, the general capacity of 18650 lithium battery between 1200mah ~ 3600mah, and through the battery series and parallel composition of the 18650 battery pack, capacity can be greatly enhanced.

The 18650 battery has no memory effect, so it is more convenient to use without emptying the remaining power before charging.

Long Life, lithium ion battery 18650 service life is very long, normal use cycle life can reach 500 times more than ordinary batteries more than twice.

High Safety Performance, 18650 Lithium Battery High Safety Performance, no explosion and no pollution of the environment. Because the positive and negative electrodes of the 18650 lithium battery are separated, the possibility of short circuit in most cases has been reduced to the extreme. In addition, the 18650 lithium battery can be installed with a protective plate, on the one hand to avoid overcharge and overdischarge, but also to achieve the effect of extending the service life of the battery.

Small internal resistance, less irreversible capacity loss, which greatly reduces the battery’s own power consumption, extended standby time.

Where is the 18650 battery used for?

As the earliest lithium ion battery, the lithium battery 18650 is also the most mature and stable battery pack in the world, and is far ahead of other lithium battery products in market share. The 18650 battery is widely used. In addition to being used in power industries such as electric vehicles, lithium 18650 is also used in digital products, medical equipment, machinery equipment, power tools and other electronic equipment.

We provide green and high-quality energy ( lithium polymer battery ) for prototype companies. When our lithium ion battery can be designed into the product being developed and then successfully sold in the market, we are as excited as our customers.

Lipoly battery Life?
Standard: After 500 cycles, the capacity will be <80%.
It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.

What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answeri we gave is that you do not have this worry about these.
Because all lipoly battery we produced have reasonable tolerances:
Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.

What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.
