按照能量守恒原理，以上方法对于三相/单相或单相/单相UPS是一样的；像APC的秀康机，需正负两组（32块/组）电池，其计算原理也是一样的。注意“安时.块”的概念。
一般中大功率的UPS，每组电池都是32块；电池并联数好不要超过四组，以免影响电池组的均流和充电效果。
由上可见，一般来说，只要记住109（或126）和1.23这三个数字就够用了。
以上是快捷的粗算，不很。要想得到的结果，应利用电池厂家给出的电池放电特性表。

Guanglong long battery Co., Ltd. has been established for 20years since 1990. It is a professional lead-acid batterymanufacturer that has obtained bonded factory and stock listing inChina. In the past five years, the number of battery shipments peryear has increased by 30%, and the business income has reached 4billion yuan. In order to diversify the production risk and expandthe sales market, we adopted the production and marketing policy ofinternational division of labor. As early as 1996, we set up afactory in Binli County, Vietnam, which is a foreign-fundedenterprise with investment earlier than the local establishment ofbattery production base. After 1999 and 2000 respectively completedISO9001 and ISO14001 certification, passed OHSAS18001 certificationin 2002, and listed in Taiwan in the same year. By 2007, it hadcompleted the construction of Dehe factory in Vietnam with an areaof 200000 square meters. In 2008, it had passed the TL9000communication / communication electronic industry systemverification. From the end of 2009 to 2010, it continued to carryout the expansion project of the second and third phase of theproduction base of Dehe factory.
In the manufacturing of products, Guanglong has revolutionaryinnovation and practice from technical system to management methodand business process, in addition to strict control over allproduction links. Our products are precisely manufactured andguaranteed to follow the management system. All series ofsealed battery products have passed UL safety standard. Inaddition, we have also passed the German VDS certification for thehigh- demand of the security control market in Europe.Product is deeply loved and recognized by well-knownmultinational enterprises at home and abroad. We believe thatcustomer satisfaction not only comes from the product itself, butalso the value added of customer satisfaction can be improved byestablishing a friendly relationship with customers through instantservice provision. Therefore, Guanglong won not only the Gold Awardfor customer satisfaction, but also the "Taiwan boutique Award" bythe Ministry of economy.
Our innovation and development come from abundant experience andenergy. Guanglong has a complete product line and competitiveadvantage in flexible manufacturing technology. So far, it hasdeveloped more than 400 kinds of batteries for different purposes,and continues to develop batteries for renewable energy such aselectric vehicles, solar energy and wind power. For the endlesspursuit and attitude of product innovation and development,Guanglong has cooperated with the Institute of materials of theInstitute of engineering and research since 1993 to develop thesealed battery for deep discharge, the battery for electric motorvehicles and the battery for high power upgrading, and introducednew technologies in many ways, and invested many advanced e show our faith and commitment to keep pace with the times andsustainable development.
Based in Taiwan, deeply ploughing in Vietnam, looking around theworld. Guanglong is committed to providing cleaner energy forglobal consumers, shouldering social and environmentalresponsibilities and maintenance, so as to drive the company'ssustainable growth and sustainable operation, and make unremittingefforts.

1. 对于设计寿命十年的电池：109（安时.块）/KVA
使用时按下列公式计算：
所需电池容量（AH）=[UPS容量（KVA）×109（安时.块）/KVA]/每组电池块数（块）
例如：一台120KVA的UPS，每组电池32块，要求后备时间60分钟。则所需电池容量为
120KVA×109（安时.块）/KVA=13080（安时.块），13080安时.块/32块=409（安时），
即可选12V，100AH电池4组；32块/组。注意：实际后备时间不足60分钟（欠一点）。
如果33块/组，则13080/33=396（安时），同样可选12V，100AH电池4组；33块/组。注意：实际后备时间超过60分钟（超一点）。
如果要求后备时间30分钟，则109×120=13080（安时.块），13080/32=409（安时），
409/2=205（安时）。
由于电池的放电功率与放电时间不是线性的，即不能只简单除以2，还需乘个修正系数，见下表，205×1.23=252安时。即可选12V，65AH电池4组；32块/组。注意：实际后备时间超过30分钟（超一点）。
如果要求后备时间20分钟，则409/3=136（安时），还需乘个修正系数，见下表，136×1.41=192（安时），即可选12V，65AH电池3组；32块/组。注意：实际后备时间超过20分钟（超一点）。
其它情况，以此类推。
2. 对于设计寿命五年的电池：126（安时.块）/KVA
计算方法和需乘修正系数与前述完全一样；只是要把上式中的109换成126。
如果计算时间是一小时以上，要在按上述计算后再除以个修正系数，见下表。
例如：前例的后备时间是3小时，则109×120=13080（安时.块），13080/32=409（安时），409×3=1227（安时）；还需除个修正系数，见下表，1227/1.25=982（安时）。
