UPS lead-acid battery life is related to many factors, can not be generalized, the battery life depends largely on the battery environment, processing technology and storage state. General single 12V lead-acid battery design float life of 5-8 years, but 1-2 years has been completely obsolete.
How many years is the service life of UPS battery?
The life of UPS batteries is generally about 2-3 years, if used and maintained properly, it can be used to more than 4 years. If they are not properly used and maintained, they can be damaged early within a few months.
UPS batteries should be used to regularly check the height of the electrolyte, and timely inspection and replenishment of the battery's storage condition. Battery maintenance is relatively simple, do a good job of electrolyte replenishment, battery and pole pile cleaning and battery specific gravity control, etc., you can effectively extend the service life of UPS batteries. Due to the widespread use of maintenance-free batteries, batteries in normal operating conditions, generally do not require maintenance.
General single 12V lead-acid battery design float life of 5-8 years, but 1-2 years has been completely obsolete; regardless of any lead-acid batteries, in use always escape the cycle of early obsolescence.
From the point of view of use and maintenance, whether your car is equipped with maintenance-free batteries or general batteries, the normal service life of about 2-3 years. As for wanting to extend the service life of UPS batteries, general batteries can be used for about 3 years after the addition of electrolyte, thus extending the life of 1-2 years.
The following Factors affect the service life of UPS batteries
1, Depth of discharge
Depth of discharge, that is, the use of the process of discharge to what extent to start to stop. 100% depth refers to the discharge of the full capacity, lead-acid battery life is greatly affected by the depth of discharge. The focus of design considerations is deep cycle use, shallow cycle use or float use. If the shallow cycle use of the battery for deep cycle use, the lead-acid battery will fail quickly.
2, Degree of overcharging
Overcharging a large number of gas precipitation, the positive plate active material suffered a gas shock, this shock will prompt the active material off; In addition, the positive plate grid alloy also suffered serious anodic oxidation and corrosion, so the UPS battery overcharging will shorten the period of use.
3, Impact of temperature
UPS battery life with the temperature increases and extends. Between 10 ℃ ~ 35 ℃, every 1 ℃, about an increase of 5 ~ 6 cycles, between 35 ℃ ~ 45 ℃, every 1 ℃ can extend the life of more than 25 cycles; higher than 50 ℃ due to the negative sulfide capacity loss and reduced life.
UPS battery end-of-life reasons
UPS battery failure refers to the new lead-acid batteries are not used on the failure of the scrap, the original cause is: lead-acid battery manufacturing materials in the combination of active substances is unreasonable; pole plate in the chemical solution does not meet the charging and discharging standards; pole plate storage environment is poor or storage time is too long, sealing is damaged, in the air for a long time in the oxidation of the pole plate, resulting in the active substance is aging;
Improper maintenance in the process of use, a single body for a long time in the de-energized state, high-current discharge de-energized single body after the emergence of anti-pole voltage, but still not in time to the battery maintenance: such as adjusting the density of the electrolyte, plus distilled water, to the battery to replenish the battery, resulting in irreversible sulfurization of the single body and failure.
In the use of UPS batteries, often in the summer is not timely to the battery water, high temperatures and evaporation lead to electrolyte shortage or dry, so that the electrolytic surface of the plate exposed to the air and hydrogen oxidation brittle lead to plate vulcanization and necrosis.
UPS lead-acid battery failure and scrap, in addition to a part of the mechanical parts damaged and scrap, and the vast majority of lead-acid battery failure belongs to the plate active material surface to form an irreversible sulfide after the failure of the scrap. Therefore, the problem of irreversible sulfation of lead-acid battery plates is still a topic to be tackled by the majority of industry personnel in the field of storage batteries.
Included in the original cause of dangerous goods is the internal corrosive sulfuric acid solution and the heavy metal lead, whether sulfuric acid or lead, on people, animals and plants, soil are harmful, so the end of the UPS lead-acid batteries can not be thrown.
