What is the pulse cranking amp rating (PCA)?
Unlike CCA and MCA the pulse cranking ampere (PCA) rating does not have an "official" definition; however, we believe that for true engine start purposes, a 30 second discharge is unrealistic. With that in mind, the PCA is a very short duration (typically about 3 seconds) high rate discharge. Because the discharge is for such a short time, it is more like a pulse.

What is the Amp Hour (Ah) rating?
An amp-hour is one amp for one hour, or 10 amps for 1/10 of an hour and so forth. It is amps X hours. If you have something that pulls 20 amps, and you use it for 20 minutes, then the amp-hours used would be 20 (amps) X .333 (hours), or 6.67 AH. The accepted AH rating time period for batteries used in solar electric and backup power systems (and for nearly all deep cycle batteries) is the "20 hour rate". This means that it is discharged down to 10.5 volts over a 20 hour period while the total actual amp-hours it supplies is measured. Sometimes ratings at the 6 hour rate and 100 hour rate are also given for comparison and for different applications. The 6-hour rate is often used for industrial batteries, as that is a typical daily duty cycle. Sometimes the 100 hour rate is given just to make the battery look better than it really is, but it is also useful for figuring battery capacity for long-term backup amp-hour re

What is a MilliAmp Hour (MAH)?
MilliAmp Hour means how much current a battery will discharge over a period of one hour. Higher numbers here reflect a long battery runtime and or higher storage capacity. Higher MAH ratings do not necessarily reflect on speed but more on runtime. For example a 2000 mAh pack will sustain a 2000 milli amp (2 amp) draw for one hour before dropping to a voltage level that is considered discharged. A 1700 will sustain a 1700 mAh (1.7 amp) draw for one hour. 1000 mAH is equal to a 1 Amp Hour (AH) rating.

后备交流电源的重要性
后备交流电源是许多行业的动力保证， 保证了供电的连续性，保证了供电系统的安全性，后备交流电源时刻发挥着重要的安全保障作用，
一个良好的后备电源系统是应对灾难的重要力量。台风、地震等自然灾害经常会损坏电源供电线路，重建这些线路往往需要一段时间。而在灾难面前，动力中断就意味着信息的中断、光明的中断、甚至，生命的中断。此时，发电油机、UPS（不间断电源）、蓄电池等后备电源必须撑起应急系统的动力大梁，各级维护管理部门要从确保运行质量，生产安全和财产安全的角度来重视UPS、发电机等后备电源的维护工作了……
各类后备交流电源维护现状及普遍存在的问题

1、无法检测发电机实际输出功率及带载能力：发电机新安装验收投入使用时没有手段测试发电机的输出功率及带载能力。维修或噪音改造后发电机的输出功率及带载能力。
2、无法检测交流不间断电源——UPS及DC/AC交流逆变电源设备电气性能指标，无法检测UPS实际输出功率及带载能力：新安装的UPS/EPS没有手段在投入使用前进行带载测试，定期日常维护中也缺乏有效检测手段（没有维护工具）进行维护测试。
3、无法掌握UPS/EPS运行使用中的大容量阀控电池容量及寿命，由200多节2V电池组成的电池组往往由于电池节数多，放电电流大，找不到合适的手段进行放电测试。
4、无法检测开关电源、直流变换设备电气性能指标：新装开关电源及DC/DC直流变换电源设备工程竣工验收及日常运行维护例行检测中，使用部门由于缺乏直流电源设备参数检测设备，无法检测设备电气性能指标，不但影响了工程验收，还给运行维护带来一定的困难。
