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.
什么是脉冲曲柄放大器额定值(PCA)？与CCA和MCA不同的是，脉冲曲柄安培(PCA)等级没有“官方”定义；然而，我们认为，为了真正的发动机起动目的， 30秒的放电是不现实的。考虑到这一点，PCA是一个非常短的持续时间(通常约3秒)高速率放电。因为卸货时间这么短，所以更多的是l。 像脉搏一样。安培时(啊)的评分是多少？一个安培小时是一个安培一个小时，或10个安培1/10小时，以此类推。是安培X小时。如果你有20安培的东西，而你 使用它20分钟，然后使用的安培小时将是20(安培)X.333(小时)，或6.67 AH.用于太阳能和备用电力系统的电池的公认的AH额定时间(以及 几乎所有的深循环电池都是“20小时费率”。
UPS电源的维护与使用是分不开的，有科学的使用方式还应该有正确的维护方法，这样才能达到UPS的高利用率。
