There may be two reasons for the battery drum package. One is the problem of battery manufacturing level, the electrode coating is uneven, and the production process is rough.

The current popular lithium battery chargers are full of self-stopping, there is no ‘overcharged’ and you don’t have to worry about charging

Nowadays mobile phones have become our must-have communication tools, but in order to make your mobile phone use longer and safer, you must know the correct charging method of the mobile phone

We first check if the battery is missing electrolyte. (Of course, you can check if there is a short circuit.)

A set of batteries can be used for more than 5 years under correct charging and normal maintenance.

How long will the lithium battery last in electric cars? Believe that the vast majority of consumers have heard of, the life of the lithium battery is “500”

Normal call is “charge and discharge cycle”, is not equal to “charge times”, cycle refers to, the battery from full charge to use up, this is a cycle

The principle is different, let’s start with lithium batteries and lithium ion batteries (polymers are also a kind of lithium ion battery).

Lithium polymer batteries are safe. Why? Mainly packaging plastic film, the battery is in a relatively high ductility
