In order to ensure the battery recycling, new purchased of NI-MH battery needs longer time to be charged for the first time In principle, we should make sure it is fully charged and discharged.

Lithium-ion battery transportation including air, sea, land, here we mainly discuss air shipment and sea shipment Because lithium is a metal which is particularly prone to occur chemical reaction, easy to extend and burning.

A summary of common faults of lithium-ion battery includes capacity of lithium-ion battery, internal resistance of battery, voltage, super thick size, open circuit and so on These happen frequently during production.

The energy of a battery: refers to the output of electric energy by a certain discharge condition Specific energy: the battery energy per unit weight or unit volume, it is called weight specific energy or volume specific energy.

It is believed that many people have heard that new energy vehicle has two kinds of power battery: ternary lithium battery and LiFePO4 battery So, what's the difference on the performance between these two different materials? What causes these differences? Due to the change of government subsidies tendentiousness, BYD has achieved mass production in the field of LiFePO4 battery in the past, and turn to the large-scale development of ternary lithium.

A lot of people now join battery repair industry Most of them join crown power battery repair industry.

Lithium ion batteries charge and discharge rate determine the speed of how fast we can storage certain amount of energy into battery inside, or how fast release the inside energy of the battery Of course, the storage and release process is controllable and safe, which will not significantly affect the service life of battery and other performance indicators.

Once a factory has mixed 1000 mAh and 2200 mAh battery together, everyone is very depressed How do we distinguish the battery? You can measure the weight.

18650 battery can be said to be the earliest lithium ion batteries, designed and developed by Japan SONY company, carried forward by Panasonic, Samsung After more than 20 years development, the preparation technology is already very mature, battery performance also has a great improvement.

Downside is that it is not a pure battery, joined the step-down voltage stabilizing circuit, charging circuit, these costs are to consumers, and load cell volume and capacity is much smaller than pure battery of the same size and material Cannot control, another is capacity before the run out of electricity, you don't know how it has power, you can't judge capacity by measuring the voltage.
