Does Panasonic Battery Loss Batteries after Long Storage

Panasonic batteries will discharge more or less during storage. The normal Panasonic battery loses about 1%-2% of its power capacity every day, that is, a fully charged Panasonic battery loses about half of its power capacity after one month of storage.



Cause of self-discharge



1. Panasonic battery has iron or short circuit outside. When the lead of Panasonic battery is tied up with the body, or conductors such as wrenches and wires are connected with the positive and negative electrodes on the shell of Panasonic battery, it will produce intense self-discharge and soon the electric energy will be released. In addition, when there is spilled electrolyte on the shell and top cover of Panasonic battery, the positive and negative poles can also be connected and discharged.



2. The positive and negative plates are directly connected and short-circuited when the battery separators are eroded, perforated, damaged or deposited under the positive and negative plates, resulting in the self-discharge of Panasonic batteries.



3. The electrolyte is impure, contains impurities, or is not pure water added. At this time, impurities in the electrolyte adhere to the plate with the activity of the electrolyte, forming a certain potential difference between the impurities, it will form a lot of small batteries with self-made paths inside Panasonic batteries, making Panasonic batteries often in a short-circuit state. The test shows that if the electrolyte contains 1% iron, Panasonic battery will discharge all the electric energy within 24 hours after it is fully charged.



4. Panasonic battery plate itself is not pure, contains more impurities, will also form a lot of small batteries and self-discharge.



5. Panasonic batteries are stored for too long. Water and sulphuric acid in the electrolyte are stratified due to different specific gravity, which makes the density of the electrolyte smaller and larger, and forms potential difference and discharges itself.



Loss of Panasonic Batteries



1. Contamination deposited on the upper and lower parts of the plate causes short circuit.



2. The deformation of the electrode plate results in the contact between the positive plate and the cladding plate, which results in short circuit.



3. Overdischarge, the discharge protection circuit of UPS power supply is abnormal, and the load of UPS power supply is too small to form deep discharge of battery.



4. Batteries are stored for a long time (they are not charged during storage), and they will fail if they are not used for a long time.



5. Charging with unqualified chargers, some chargers have no current limiting devices, resulting in battery damage.



6. There is no electrolyte. It has been used for a long time. The electrolyte can be replenished once a year.



7. The proportion of electrolyte is too high.



8. Charging under high temperature conditions, the protection rate of lead-acid batteries is relatively low in the process of operation because of the continuous improvement of current lead-acid batteries'skills. However, users must not neglect management because of its "protection-free" nature.
