What is the pulsecranking amp rating (PCA)
Unlike CCA and MCA the pulsecranking ampere (PCA) rating does not have an "official"definition; however, we believe that for true engine startpurposes, a 30 second discharge is unrealistic. With that in mind,the PCA is a very short duration (typically about 3 seconds) highrate discharge. Because the discharge is for such a short time, itis more like a pulse.
What is the AmpHour (Ah) rating?
An amp-hour isone 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, andyou 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 timeperiod for batteries used in solar electric and backup powersystems (and for nearly all deep cycle batteries) is the "20 hourrate". This means that it is discharged down to 10.5 volts over a20 hour period while the total actual amp-hours it supplies ismeasured. Sometimes ratings at the 6 hour rate and 100 hour rateare also given for comparison and for different applications. The6-hour rate is often used for industrial batteries, as that is atypical daily duty cycle. Sometimes the 100 hour rate is given justto make the battery look better than it really is, but it is alsouseful for figuring battery capacity for long-term backup amp-hourrequirements.
What is aMilliAmp Hour (MAH)?
MilliAmp Hourmeans how much current a battery will discharge over a period ofone hour. Higher numbers here reflect a long battery runtime and orhigher storage capacity. Higher MAH ratings do not necessarilyreflect on speed but more on runtime. For example a 2000 mAh packwill sustain a 2000 milli amp (2 amp) draw for one hour beforedropping to a voltage level that is considered discharged. A 1700will sustain a 1700 mAh (1.7 amp) draw for one hour. 1000 mAH isequal to a 1 Amp Hour (AH) rating.
What is aVOLT?
A Volt is the unit of measurefor electrical potential.
What is aWATT?
A WATT is the unit for measuringelectrical power, i.e., the rate of doing work, in moving electronsby, or against, an electrical potential. Formula: Watts = Amperes xVolts.
What is aWATT-HOUR (Watt-Hr, WH)?
A WATT-HOUR is the unit ofmeasure for electrical energy expressed as Watts xHours.
What is anOHM?
OHM is a unit for measuringelectrical resistance or impedance within an electricalcircuit.
What is OHM'SLaw?
OHM’S Lawexpresses the relationship between volts (V) and amperes (A) in anelectrical circuit with resistance (R). It can be expressed asfollows: V= IR Volts (V) = Amperes (I) x Ohms (R). If any two ofthe three values are known, the third value can be calculated usingthe above equation.
What isElectrolyte?
In a lead-acid battery, theelectrolyte is sulfuric acid diluted with water. It is a conductorthat supplies water and sulfate for the electrochemicalreaction:
What is theproper electrolyte level?
Liquid levels should be 1/8 inchbelow the bottom of the vent well (the plastic tube that extendsinto the battery). The electrolyte level should not drop below thetop 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6.67AH.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”。这意味着它在20小时内放电到10.5伏特，而实际供应的总安培小时是测量的。有时r此外，当局亦按6小时及100小时的殴打率进行比较及不同的申请。工业电池通常使用6小时的倍率，因为这是一个典型的每日占空比。有时100小时的速度只是为了使电池看起来比实际更好，但它也是有用的计算电池容量的长期备份和小时要求。什么是毫安小时(MAH)？毫安小时是指电池在一小时内放电的电流。这里的数字越高，电池运行时间越长，或者存储容量越大。高丽 rMAH评级不一定反映速度，而更多地反映运行时。例如，一个2000mAh封装将维持一个2000毫安(2安培)抽奖一个小时，然后下降到一个电压水平，即co。已出院。1700将维持一个1700毫升(1.7安培)的抽签一个小时。1000Mah等于1安培小时(AH)等级。伏特是什么？伏特是测量电势的单位。..瓦特是什么？瓦特(美国瓦特)是测量电能的单位，即工作的速度，使电子通过或对着电势移动。公式：瓦茨=安培x伏特。Wha是瓦特小时(瓦特-HR，WH)？瓦特小时是以瓦茨x小时表示的电能计量单位.欧姆是什么？欧姆是测量电阻或阻抗w的单位。有电路。欧姆定律是什么？欧姆定律描述了电阻(R)的电路中电压(V)和安培(A)之间的关系。它可以表示如下： =IRVolts(V)=安培(I)x欧姆(R)。如果这三个值中的任何两个已知，则可以使用上述方程计算第三个值。电解质是什么？在铅酸电池中，电溶质是用水稀释的硫酸。它是为电化学反应提供水和硫酸盐的导体：合适的电解质水平是多少？液位应为1/8英寸在通风井底部下面(伸入电池的塑料管)。电解液水平不应下降到极板顶部以下。
蓄电池经历一次充电和放电，称为一次循环（一个周期）。在一定放电条件下，电池工作至某一容量规定值之前，电池所能承受的循环次数，称为循环寿命，各种蓄电池使用循环次数都有差异，传统固定型铅酸电池约为500~600次，起动型铅酸电池约为300~500次。阀控式密封铅酸电池循环寿命为1000~1200次。
影响循环寿命的因素一是厂家产品的性能，二是维护工作的质量，固定型铅电池用寿命，还可以用浮充寿命（年）来衡量，阀控式密封铅酸电池浮充寿命在10年以上，对于起动型铅酸蓄电池，按我国机电部颁标准，采用过充电耐久能力及循环耐久能力单元数来表示寿命，而不采用循环次数表示寿命。即过充电单元数应在4以上，循环耐久能力单元数应在3以上。
