What is the difference between nickel metal hydride batteries and lithium 18650 li ion battery?

　　When consumers purchase rechargeable batteries, they are often confused about the many types of rechargeable batteries and do not know which one meets their needs. After all, they still don't understand the difference between the two. So, what is the difference between nickel-metal hydride batteries and lithium 18650 li ion battery?

　　NiMH batteries.

　　First, the difference in volume size.

　　Relatively speaking, the capacity of lithium 18650 li ion battery is larger than that of nickel-metal hydride rechargeable batteries, but it is "relatively speaking". Because the capacity of lithium 18650 li ion battery of the same volume is higher than that of nickel-metal hydride batteries, lithium 18650 li ion battery are relatively smaller, lighter, and easier to carry around. They are especially suitable for various new mobile terminals, such as mobile phones, computers, PDAs, etc. lithium 18650 li ion battery have no memory, so they can be charged whenever they are used. However, overcharging the battery will shorten the service life of the rechargeable battery, so multiple batteries can be charged. Ni-MH rechargeable batteries have low memory, so it is generally best to recharge the battery after the rechargeable battery is exhausted. As everyone knows, there is a matter of priority. If there is an emergency, you can charge it immediately without releasing the electricity inside. In addition, the lithium battery life rate of lithium 18650 li ion battery is very low, so the power consumption stored in the rechargeable battery can always be maintained.

　　Second, how much power is there?

　　There are many differences between nickel-metal hydride rechargeable batteries and lithium 18650 li ion battery. The power storage is on the same level. Customers are widely concerned about battery capacity. Compared with nickel-metal hydride rechargeable batteries, lithium 18650 li ion battery have greater energy density, that is, in the same volume, rechargeable batteries contain more power than nickel-metal hydride rechargeable batteries. Therefore, the batteries used in automatic phones like ours are generally lithium 18650 li ion battery, which are light in weight, small in size, and can meet certain volume requirements.

　　Third, the self-discharge effect of lithium 18650 li ion battery.

　　To put it bluntly, lithium battery life is the performance loss of the battery when it is not used, that is, the battery's ability to maintain power consumption. The greater the lithium battery life efficiency, the shorter the service life of the rechargeable battery. If the lithium battery life rate of a rechargeable battery is too high due to a series of reasons, its service life is likely to be shortened directly. Lithium battery life rates vary between lithium and nickel metal hydride rechargeable batteries. Although their lithium battery life effect is not obvious, the latter type of lithium battery life is a common phenomenon. Due to the different natural stones used, lithium 18650 li ion battery have great advantages in maintaining power. If you feel that the nickel metal hydride rechargeable battery has a low battery life, you can immediately ignore the lithium battery life. To a certain extent, lithium 18650 li ion battery can be regarded as a new type of battery that is better than nickel-metal hydride rechargeable batteries and can be used as a better product to replace nickel-metal hydride rechargeable batteries.

　　Fourth, size

　　NiMH batteries.

　　Nickel-metal hydride batteries have been used on the market significantly longer than lithium 18650 li ion battery. So far, nickel-hydrogen batteries have many specifications and models for consumers to choose from, such as the "special-shaped nickel-hydrogen batteries" that we often hear, that is, nickel-hydrogen batteries of different specifications. However, because the purpose of lithium 18650 li ion battery is more practical, the specifications of lithium 18650 li ion battery are also more practical.

　　Fifth, the main uses are also different.

　　With the popularity of computers and mobile phones, the market's demand for mobile phones is increasing, especially lithium 18650 li ion battery for mobile phones. In addition to the data electronics industry, lithium 18650 li ion battery are also widely used in new energy vehicles, mobile base stations and other places. Nickel metal hydride batteries are generally used in electrical equipment, lighting fixtures and electric toys.

　　This is probably the difference between nickel-metal hydride batteries and lithium 18650 li ion battery. When choosing, you must choose a suitable battery according to your specific needs.
