Lithium batteries on the market have increased their installation rate due to their lightness and long cycle life, which are conducive to improving the range of electric vehicles.
But its chemical properties are more reactive than lead-acid batteries, if used improperly, once a short circuit occurs, high temperature will appear deflagration risk, will endanger the life safety of the owner!
Therefore, the maintenance master told everyone.
When buying lithium batteries, you also need to pay attention to the following points
1. What kind of lithium battery has a higher risk of spontaneous combustion?
Although lithium batteries have the potential risk of spontaneous combustion, not all lithium batteries will spontaneously combust, which is a high probability of spontaneous combustion for Class 3 batteries, so don't buy it.
Severely aged lithium batteries:In the case of lithium dendrites inside the battery, there is a high risk of spontaneous combustionLithium batteries of poor quality:The production process and materials of lithium batteries are extremely demanding, and low-quality batteries are unsafeTampered lithium batteries:Manufacturers or merchants change lithium batteries without permission, resulting in mismatch with the parameters of electric vehicles, and there is also the possibility of spontaneous combustion. 
Recently, the market supervision bureaus in many places are also investigating the quality of lithium batteries.
It is also clarified that there are three types of batteries that cannot be bought or sold
2. 3 kinds of batteries are not allowed to be bought and sold
The factory quality sampling inspection is unqualified:For lithium battery factory quality sampling, for sampling unqualified products, prohibit trading, Dongguan Market Supervision and Administration to carry out electric bicycle lithium battery product quality rectification and improvement action. 
"Three-no" lithium battery:For the "three no" products we are already very familiar with, this is also the electric vehicle market focus on the investigation and handling of the project, three no including no brand name, production address, no product implementation standards, such products often come from small workshop production, the safety is very low. 
There is a problem with battery tampering:With the implementation of the new national standard, the battery must be 48V, tampering with the battery has become common, and some dealers have changed the 48V battery to 60V or even higher, which increases the risk of spontaneous combustion and prohibits merchants from buying and selling.
