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.

What is a VOLT?
A Volt is the unit of measure for electrical potential.

What is a WATT?
A WATT is the unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by, or against, an electrical potential. Formula: Watts = Amperes x Volts.

What is a WATT-HOUR (Watt-Hr, WH)?
A WATT-HOUR is the unit of measure for electrical energy expressed as Watts x Hours.

What is an OHM?
OHM is a unit for measuring electrical resistance or impedance within an electrical circuit.

What is OHM'S Law?
OHM’S Law expresses the relationship between volts (V) and amperes (A) in an electrical circuit with resistance (R). It can be expressed as follows: V= IR Volts (V) = Amperes (I) x Ohms (R). If any two of the three values are known, the third value can be calculated using the above e

What is Electrolyte?
In a lead-acid battery, the electrolyte is sulfuric acid diluted with water. It is a conductor that supplies water and sulfate for the electrochemical reaction:

What is the proper electrolyte level?
Liquid levels should be 1/8 inch below the bottom of the vent well (the plastic tube that extends into the battery). The electrolyte level should not drop below the top of the plates.

我们在负载小功率设备的设备，如果设备本身对电能的要求不是很高的话，一般情况下都使用后备式的UPS电源来进行负载，下面我们工程师就给大家讲解后备式ups电源有哪些优点和缺点？

后备式UPS电源的优点是:产品价格低廉，运行费用低。由于在正常情况下逆变器处于非工作状态，电网电能直接供给负载，因此后备式UPS的电能转换效率很高。蓄电池的使用寿命一般为3~5年。

后备式UPS电源的缺点是:当电网供电出现故障时，由电网供电转换到逆变器供电存在一个较长的转换时间。对于那些对电能质量要求较高的设备来说，这一转换时间的长短是至关重要的。再者，由于后备式UPS电源的逆变器不是经常工作，因此不易掌握逆变器的动态状况，容易形成隐性故障。后备式UPS电源一般应用在一些非关键性的小功率设备上。
