Can be reliable, repair success rate is very low. The principle of the battery is to charge and discharge through chemical reactions of internal chemical raw materials. When the battery is worn out, the chemical raw materials it contains are neutralized and the ability to react chemically is lost.
Manufacturers use special precision equipment to use chemical methods to artificially transform the two raw materials into positive and negative ion forms. After a long time of use, a small part of the ions will be neutralized and become stable. The atomic form is no longer charged. To repair them, only the manufacturer's precision equipment can do it.
Lithium manganese batteries typically have a voltage rating above 3.0 volts and are best suited as integrated circuit power supplies and are widely used in computers.ators, calculators and watches. Lithium-ion batteries are widely used in mobile phones, laptops, power tools, electric vehicles, emergency power supplies for street lights, navigation lights and small household appliances.
Irreparable batteries
1. Used for over 2 years.
2. Bulging caused by long-term loading.
3. This is a special situation. Some stores use batteries that are used daily and charged 3-4 times per day. This type of battery usually lasts less than a year or just past the warranty period. Scrap and beyond repair.
4. The broken grid is caused by the aging of the internal plates.
It is relatively complicated to repair a battery with single block problems. There is no repair value due to aging, severe vulcanization, fwater leak, bulge and deformation, broken grille, pole piece falling or deformed, etc.
