dell Latitude X300 Battery

Emerson iTrust UL33 UPS battery management program


Battery is an electricity storage device, dell laptop battery when the two metals (usually there are differences in the nature of the metals) are immersed in the electrolyte, which can be conductive, and in the “plate” a certain electromotive force between (Figure 1). Electromotive force size (or voltage) and the metal used, and different types of 92p1060 battery, 92p1061 battery,1G222 Battery, BAT3151L8 Battery
Latitude X300 Battery, W0465 Battery, 92p1071 battery of its electromotive force are also different. Refers to the lead-acid batteries made of lead dioxide positive electrode, lead for the negative activity, for sulfuric acid battery electrolyte. It consists of the battery shell, positive and negative electrode, electrolyte, separators and other parts. Lead-acid battery charging and discharging of the chemical reaction process is as follows:


Reversible charge and discharge the above equation with the expression of a rechargeable lead-acid battery energy storage and discharge characteristics, each monomer has a 2V battery electromotive force. Use when the battery in series to obtain the necessary high voltage batteries in parallel can also be required to obtain a larger capacity


Electrolyte by the existence of lead-acid batteries in a way, W0465 Battery,divided into open-type lead-acid batteries (liquid-rich) and valve-regulated lead-acid batteries (poor liquid) sealed lead-acid battery. VRLAB working principle is: the gas re-combination, namely:1G222 Battery, BAT3151L8 Battery
Latitude X300 Battery, W0465 Battery, positive oxygen generated through the pores of the AGM separators (or Colloid cracks) and the negative of living material and sulfuric acid reaction, and then synthesis of water, At the same time, so that part of negative plates in a discharge state, thereby inhibiting the generation of hydrogen. As long as the positive plate of oxygen have negative plate does not exceed the speed of oxygen absorption rate, the battery will not have a surplus of gas, the battery will not be water loss, we can achieve the seal. The actual process of the batteries in actual use, there is always a small amount of gas can not be further compounded, in order to prevent the internal pressure of the battery, the battery is installed in a one-way valve, remove the internal battery gas surplus, and this is the so-called valve.


VRLA Battery features low maintenance, it can be used in the office environment, the current configuration of the UPS batteries fully used VRLA batteries.


The basic parameters of the battery include: battery electromotive force, open-circuit voltage, the termination voltage, operating voltage, discharge current, capacity, specific energy, the battery internal resistance, storage performance, service life (floating discharge cycle life), etc.;Latitude X300 Battery, performance indicators include: the largest discharge current, resistance Overcharge ability, capacity to preserve the rate of response to the performance of sealed, valve action, explosion-proof performance, anti-mist properties.


Terminology involved in the battery (UPS battery standard, see the Japanese Industrial Standards JISC 8702-1995)


1, capacity: Ah capacity, Wh capacity,1G222 Battery, BAT3151L8 Battery
Latitude X300 Battery, W0465 Battery, in the choice of UPS 92p1073 battery, 92p1075 battery, 92p1077 battery configuration, in accordance with customer requirements Preparation of electrical system loaded with time, under full load can be calculated by Wh battery discharge the number of battery manufacturers in accordance with the different capacity of batteries Different discharge time of the Wh data tables, look-up table to control, when there is no such data shall be required to provide manufacturers;

2, the discharge rate: According to IEC standards, the time rate of discharge rate and the minute-hour 20,10,5,3,1,0.5 rate, respectively, expressed as: 20Hr, 10Hr, 5Hr, 3Hr, 2Hr, 1Hr, 0.5Hr and so on.


C10 - 10h the rate of nominal capacity A h,BAT3151L8 Battery value of 1.00 C1


C3 - 3h rate of nominal capacity A h, value of 0.75 C10


C1 - 1h rate of nominal capacity A h, value of 0.55 C10


Ct - measured battery capacity A h, is the discharge current I (A) and discharge time t (h) of the product


Ce - in the basis of temperature (25 ℃) conditions at the time of the actual battery capacity, A h


I10 - 10h the rate of discharge current, value of 1.00I10 (A)


I3 - 3h rate of discharge current, value of 2.50I10 (A)


I1 - 1h rate of discharge current,1G222 Battery, BAT3151L8 Battery
Latitude X300 Battery, W0465 Battery, value of 5.50I10 (A)


In the choice of valve-regulated lead acid (VRLA) battery cells in accordance with different types of the area, supporting the use of the UPS should take full account of its large current discharge capacity,1G222 Battery, low current type of access network should be fully taken into account a long time discharge the battery deep resistance charge-discharge capacity and to restore the ability of different applications we are concerned about different indicators.


Electrochemical characteristics of the battery determines the battery life is a period of devices and reasonable use and management in order to guarantee the health of the battery.
