The final version of this document will be published as ATIS-0600330.2008. The Alliance for Telecommunication Industry Solutions (ATIS) is
4、a technical planning and standards development organization that is committed to rapidly developing and promoting technical and operations standards for the communications and related information technologies industry worldwide using a pragmatic, flexible and open approach. Over 1,100 participants f
5、rom over 300 communications companies are active in ATIS 22 industry committees and its Incubator Solutions Program. Notice of Disclaimer end voltage of 1.75 V/cell; ambient temperature of 25C. This capacity is usually designated as C8. Other capacities often used are C5 and C3. Unless otherwise spe
6、cified, these use an end voltage of 1.75 V/cell and an ambient temperature of 25C. Any new VRLA cell (or module) received by the user shall be capable of delivering at least 100% of its rated capacity when discharged after floating for one week. 4.2 Charging The cell (or module) shall be charged at
7、the float voltage recommended by the manufacturer, and the current should be limited to C8/5 unless otherwise specified by the supplier. 4.3 Float operation The float voltage of the battery shall be adjusted to the manufacturers recommended cell float voltage multiplied by the number of series conne
8、cted cells in the string. The range of battery float voltage shall be within the minimum and maximum cell float voltage values specified by the manufacturer times the number of series connected cells in the string. Three months after battery installation and acceptance the float voltage of any cell
9、(or module) in the string shall not deviate by more than 2.5% from the average cell (or module) voltage. NOTE Temperature compensation of float voltage may be required in some applications, especially in those with a wide variation of the ambient temperature (non- controlled environment). See 4.12 a

In addition, the cell (or module) shall withstand at
11、least 20 cycles to 5% depth of discharge at the five- hour rate for each year of the specified service life. 4.5 Series connection of cells (or modules) The cells (or modules) connected in series to make up a battery string for telecommunication load equipment shall be of the same make, type and rat

13、 cell should be at least 90% on an Ah basis. RE Ah removed Ah returned = 100 4.7.2 Recharge time On float, the cell (or module) should be capable of being recharged to 90% of the ampere- hours removed within 24 hours and replace 100% within 7 days. 4.8 Discharging The lowest voltage produced when th
14、e battery state changes from float to discharge including any transients, shall not be less than the end voltage specified by the manufacturer at a given discharge rate. The cell (or module) shall be characterized at both constant current and power discharge rates of 1, 3, 5, 8, 10, and 24 hours to
15、the end voltages of 1.75, 1.78, 1.80, 1.82, 1.84, 1.86, 1.88, and 1.90 V/cell. When a battery during discharge under any of the rates or end voltages specified has reached its end voltage, no individual cell shall have a voltage lower than 1.45 V or other value specified by the manufacturer. 4.9 Cel
16、l reversal Cell reversal is defined as a condition in which the cell voltage changes polarity during discharge and becomes an energy sink instead of a source. No cell in a string shall go into reversal under the specified operating conditions. 4.10 External short circuit 4.10.1 Brief short circuit A
17、fter the application of a short circuit lasting one minute, cells rated 200 Ah or less shall retain at least 50% capacity, while cells rated more than 200 Ah shall retain at least 70% of the capacity measured before the test. After recharge, all cells shall retain at least 90% of their capacity befo

Appropriate curves shall be provided by the battery manufacturer, for at least three temperatures within the recommended storage temperature range. See also 8.4, Storage. 4.12 Service life The service life of a cell (or module) is defi
21、ned as the time (in years) from the installation of the cell (or module) until its capacity falls below 80% of rated capacity. Service life shall exceed the values shown in figure 1, when operating at the temperature given on the X axis. Figure 1 Service life vs. temperature relationship 4.13 Admitt

The cells (or modules) that comprise the battery as installed and that are fully charged shall have measured values of admittance (A), conductance (G), impedance (Z), or resistance (R) in a range that complies with the manufacturers specification.
