Electric vehicle batteries are generally lead-acid batteries, charging time is generally 8 to 10 hours, should not exceed 12 hours

Lithium batteries can also be divided into two types, the cell voltage is 3.7V each 3.2V, of which 3.2V polymer battery is said to be safer than the other.

During the use of polymer lithium batteries , battery bulging may occur due to excessive charging current, overcharging, etc.

In life we all use every day to lithium batteries , such as mobile phones, laptops, 12v electric fish lithium batteries , etc.

Lithium is the most active metal in the world. Lithium-ion batteries are small in size, high in density,

Usually 18650 battery are in parallel to increase capacity, such as 20000mah mobile power is normally provided by a battery 8 or 6 3400mah 2600mah the 18650 battery into.

The power type lithium battery is a power lithium battery. The main characteristic is to support large-rate charge and discharge

Recently, there has been a rumor that the lithium battery that is about to be scrapped is put into the refrigerator for three days

Secondary batteries currently used on the market mainly include nickel-hydrogen (Ni-MH) and lithium-ion

Strictly speaking, lithium batteries are divided into two types: lithium metal batteries and lithium ion batteries.
