How to distinguish the advantages or disadvantages of 18650 lithium batteries

Due to the efficiency and safety of lithium batteries, their sales are growing even with higher prices. Consumers should pay attention to the following aspects when selecting and purchasing lithium batteries:

A, environmental temperature problems

For use rechargeable batteries, the influence of environment temperature on the battery life is often ignored by the people, under the high temperature or low temperature environment, the battery self-discharge rate will be much higher, especially the high temperature will greatly reduce the service life of battery, so before buy, need to try to communicate with engineers, given the use of their equipment or the use of environment, such ability can let the battery performance is better.

Second,lithium iron phosphate batteries equipped with safety protection circuit board

No protection circuit board, lithium electricity pool will have deformation, leakage and explosion danger. Under the malignant price competition, the search for lower price protection circuit board, or the device is omitted, makes the market full of explosion danger of lithium battery. Consumers cannot be distinguished from appearance whether there is a protection circuit board, so it's best to choose reputable stores to buy.

Third, choose the appropriate lithium iron phosphate battery brand

Lithium battery brand according to the actual needs of your choice.As for what kind of brand is more suitable for your product, you'll have to see the actual use.Can save electric lithium iron phosphate battery pack with high energy density, small volume, light weight, safety, environmental protection, long service life, good high temperature performance advantages.

Four, evaluate the lithium iron phosphate battery price

Information platform of the Internet age, we can through many B2C wholesale lithium iron phosphate batteries, such as: is the largest wholesale platform and so on .Procurement staff can go online to see different types of lithium iron phosphate battery price quotation., of course, not necessarily in the order online, can see the first price, so as to avoid fooled by others.The brand is different, the natural lithium iron phosphate battery price difference is very big also.So the lithium iron phosphate batteries wholesale going to compare and understand more.

It is important to note that the lithium iron phosphate battery pack is fraud phenomenon, and how to judge the stand or fall of lithium iron phosphate batteries?

Five, the lithium battery detection method of quality:

1, the fastest inspection method is to test the resistance and the maximum discharge current, good quality lithium battery, internal resistance is very small, and the maximum discharge current is very large. Using a 20A Range short directly connect the two electrodes of lithium-ion batteries, generally should be around 10 a current, or even higher, and can maintain for a period of time, relatively stable is good battery.

2, see the appearance. Look plump level, such as the average of around 2000mAh lithium-ion batteries, the volume is relatively large. Seems to be full work more sophisticated or packaging.

3, The hardness: Can with handle gently knead or moderate pinched in the middle part of the lithium battery, moderate hardness, no soft squeezing pressure, proving lithium batteries are relatively high quality batteries.

4, The weight: Remove the outer packing perception about the battery weight is more heavy, if the thick belongs to high quality batteries.

5, in the process of lithium battery charged work, about 10 minutes continuous discharge battery if not hot at the poles, battery protection board system perfect, general with high-quality lithium-ion battery protection board quality is better than ordinary lithium batteries.

What the above are the issues you should pay attention to while purchasing lithium iron phosphate battery, and lithium battery quality detection method. Hope that it is able to help you.
