When the battery is completed, it began to attenuate, and a new battery must supply 100% capacity, but most of the battery packs are not reached. As the battery's available area is reduced, the filling energy is reduced, and the charging time is gradually shortened. In most cases, due to cycle cycle and aging, battery capacity is linearly decayed.

In addition, the pressure caused by depth discharge to the battery is greater than that is not fully discharged, so it is best not to exhaust the battery power, but recharge. About the nickel-based battery and a smart battery as a calibration component should be discharged in a periodic depth, which helps to eliminate the memory effect of the nickel based battery. The nickel-based lithium-based battery can completely charge and discharge cycle 300 to 500 weeks before the capacity is attenuated to 80%.

The charge and discharge cycle is not the only reason for capacity attenuation, and the lithium-ion battery in high temperature can also cause capacity attenuation. A full-charged lithium ion battery will cause 35% capacity loss in the case of 40 ¡ã C (104F) for one year without being used. Super fast charge is also harmful to the battery, which will reduce the battery life, which is very obvious about the monomer lithium ion battery.

The battery pack is higher than energy, but it is particularly subtle due to the difference between the unit cell. The specifications of the equipment are often based on new batteries, but this is just a short phenomenon in the initial stage, and it cannot last too long time. Just like a sportsman, grades will gradually decline over time, and if they have developed, they will eventually lead to battery-related failures.

Battery should often calculate its capacity attenuation and final life. Capacity attenuation to 80%, to replace the battery pack, the ultimate life of the battery pack should change according to the different application, the user's preferences, and the company's guarantee. Due to the rare mechanical failure, the capacity attenuation has become a best indicator of the final alternative plan.

This indicator can be completed by a capacity verification of active batteries every three months. In addition, the technique of charging operation status characterization is also developing. In addition to the decay associated with aging, sulfate and grid corrosion are important influencing factors of lead-acid battery attenuation.

Sulfate means that the battery is formed on the cathode plate layer when the battery is in a lower magnification. If you find it in time, you can eliminate this situation by equilibrium charging. Grid corrosion can weaken by improving the charging state or using an optimized floating charging method.

Nickel-based battery, so-called unavailable rock regions are typically caused by the formation of active material crystals, also known as memory effects. The method of depth charge and discharge cycle can often restore the battery capacity to full fullness. Periodic discharge can also control the crystallization process to prevent harm to the diaphragm.

The aging of the lithium-ion battery is oxidation of internal substances and is part of the use and aging process, and it is natural and irreversible.
