Panasonic 18650 Rechargeable Batteries

Panasonic 18650 rechargeable batteries are a great way to power gadgets capable of running on lithium-ion power. Because they are rechargeable, they can be used repeatedly, resulting in less waste.

18650 Batteries

The 18650 battery type is one of the world’s most popular lithium-ion batteries. Panasonic’s 18650 batteries are used in a range of applications, including powering several Tesla vehicles. The 18650 is a cylindrical lithium-ion battery that measures 18 by 65 millimetres, the source of its name. This makes it slightly larger than a regular AA battery, which measures 14.5 by 50 millimetres. Power capacity varies from manufacturer to manufacturer, but 18650-type Panasonic lithium-ion rechargeable batteries such as the NCR18650B typically feature a capacity of around 3400mAh and discharge around 3.7 volts. Because they are rechargeable, they can be reused over and over again.

Lithium-Ion Advantages

Lithium-ion batteries deliver a number of benefits when compared to older alkaline types like the AA. They are capable of storing much more charge than an alkaline battery. They also self-discharge much more slowly, meaning that they will have to be recharged much less often when they are just sitting around. With no priming required and no memory, lithium-ion batteries are very low maintenance. However, they do suffer from a couple of disadvantages as well. Lithium-ion batteries lose capacity as they age, particularly if stored in excessively hot or cold conditions.

Other Panasonic Batteries

As well as Panasonic 18650 rechargeable batteries, there are many other types of Panasonic rechargeable batteries. This includes other lithium battery sizes like the common CR123. They also sell some more specialised lithium batteries such as the 2CR-5W, which is optimised for powering photographic flash units. Not all of their batteries are lithium-ion types, either. Panasonic continues to sell a wide range of alkaline batteries in frequently-used sizes such as AA and AAA, as well as a selection of silver oxide batteries.
