The battery is stored too long
Exist in the process in the storage battery self-discharge, if the time is not added, there will be the phenomenon of sulfate. If this is the absence of timely improved battery capacity would be reduced or even damage can not be used. Battery in the storage process, the ambient temperature also has great influence on the capacity, as shown in table 2.

(3) The base station, the ambient temperature is too high
The base station power failure, the air conditioning down. A closed room because of the base station, base stations,HP PB991A Battery indoor temperature will be increased substantially. Temperature is too high so that the internal loss of VRLA battery water intensified electrolyte saturation decreased (glass fiber cotton within the electrolyte membrane decreases) to reduce the battery capacity Normal 0 7.8 磅 0 2 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Compaq Presario CQ60 battery

(Reference: my company 12V12AH discharge the battery to 5A, discharge time of more than 150 minutes; battery life 80% DOD ≥ 540 times; battery life using the rapid test method to test the life cycle: 20A discharge the battery to 18min, Sony VGP-BPS5 Battery,hen 10A charging 42min, 1h for a cycle to the battery discharge voltage of 10.50V when the termination of the end of the trial. Express cycles ≥ 300 times the reference number of the hp pp2182l , hp 345027-001 , hp 342661-001 battery cycle life greater than 700; battery load test, motor power of 180W, distance traveled and the electric cars ≥ 52KM. )
The U.S. Army is preparing to use a "fuel cell" alternative to the currently used more than 300 species of various types of batteries.Battery is an essential of modern military equipment. From Compaq Presario CQ61 battery HP G50 battery communications equipment to surveillance equipment, from thermal imaging devices, night-vision goggles to the man, big warships plane, from the GPS receiver is not the battery. According to statistics, the U.S. military into a combat battalions fighting must be tens of thousands of portable batteries. Need of a combat load of 100 pounds foot soldiers, the battery is a heavy burden. Remove the weight, battery performance is also a problem, the traditional type of limited battery life is a common problem. compaq Presario M2000 battery (compaq m2000 battery) Even the U.S. military is developing the digital individual equipment --- "War on Land Warrior," Sony VGP-BPS10 Battery, Sony VGP-BPS8 Battery,the use of two high-performance lithium batteries is also enough to maintain the 6-8 working hours, the Army hopes to be able to work at least 12 hours.
U.S. Department of Energy Pacific Northwest National Laboratory has now developed a new micro-fuel of low-watt power supply, the device of similar shape with the lighter, the main fuel components, including micro-processors, micro fuel chamber and fuel converters. Work, first of all, the fuel converter water and special fuel will be mixed into the hydrogen-rich gases. In the fuel chamber, such gas can be broken down into hydrogen, oxygen and water can be discharged at the same time electricity. The current results show that this type of fuel cell device 5-watt output power, peak power of 25 watts, continuous working time can be more than 50 hours. In addition, the battery can be made in accordance with operational needs of different sizes, laboratory scientists use words, "just kind of a lighter shaped like a certain percentage of the battery in accordance with bigger or smaller only."Sony VGP-BPS3 Battery, HP G60 battery Sony VGP-BPS9 Battery, Sony VGP-BPS10 Battery, Sony PCG-R505 Battery,Sony VGP-BPS5 Battery, Sony VGP-BPS8 Battery, Sony VGP-BPS9 Battery, U.S. Army hoped that the battery eventually replace the current use of more than 300 kinds of various types of batteries, in order to minimize the logistical burden. The project is expected to be fully realized in 2006.
According to the U.S. "coalition of business intelligence," the report of the recent study "military fuel cell market,"Sony VGP-BPS9 Battery, Sony VGP-BPS9 Battery, predicted that by 2015, at least 45 million fuel cell use. Given the bright prospects for the development of the case, the United States have been many companies interested in investing in the production of such batteries. -
How to determine the battery - [HP laptop battery]
Matching with the inverter battery should charge and discharge can be deep-cycle lead-acid battery. Deep-discharge function for battery, the power unit of measurement is generally ampere hours (AH), it shows that the unit time (usually 20 hours) can provide current values. Hp laptop battery As for the 100AH battery capacity that can be provided within 20 hours consecutive five amps of current, that is, 20 × 5 = 100.
Battery inverter system is a very important component. Users to buy batteries, they should choose good quality and large variety of power, large-capacity battery to use for a long time for high-power electrical equipment at the same time the moment to start to provide adequate current. For some high-power electrical equipment, it is recommended batteries should be 200AH (1000W), another big power, it is best to use 400AH battery.HP HSTNN-IB73 battery
How to use electrical appliances in accordance to determine the battery capacity, the simple way is to use electrical appliances of all power, multiplied by the battery each time the use of the time between charging intervals.
