 12V2.2AH俄罗斯DELTA蓄电池DT12022 电信机房船舶电源

电池准确的充放电处理，是延伸电池寿数的重要要素，而电池维护操作的便利、活络，则是保证系统安全、易用的要害。在前期的电信机房中，一般选用将220V沟通电源经过整流，为48V电池组充电，由电池组直接给程控交流机供电。随着核算机网络和通信网络在电信机房的使用，需求为其供给高质量的220V的沟通电源

When the battery isdischarged, the metal lead is the negative electrode, whichundergoes an oxidation reaction to produce lead sulfate; Leaddioxide is the positive electrode that undergoes a reductionreaction to produce lead sulfate. When a battery is charged withdirect current, the two poles generate elemental lead and leaddioxide, respectively. After removing the power source, it returnsto its pre discharge state and forms a chemical battery. Lead acidbatteries can be repeatedly charged and discharged, and theirindividual voltage is 2V. A battery is a battery pack composed ofone or more individual cells,
