Nominal Capacity

Capacity typically delivered under standard conditions; a value greater than rated capacity which is a minimum value.

Permanent loss of Capacity

Reduction in cell capacity from the "fully formed, as new" value, measured under standard rating conditions, that is not recoverable by reconditioning.

Rated Capacity

Capacity value shown in the specification sheet. The minimum expected capacity when a new, but fully formed, cell is measured under standard conditions. The basis of the C rate. Note that rated capacities depend on the standard conditions used which may vary from battery to battery.

Residual Capacity

Capacity remaining after discharge.

Retained Capacity

Capacity remaining in a cell after an open circuit rest period. The result of self- discharge.

Standard Capacity

Cell capacity measured under standard conditions.

Temporary Loss of Capacity

Reduction in cell capacity that is recovered when the cell is reconditioned.

Cell

Electrochemical unit, composed of positive and negative electrodes, separator, and electrolyte, which is capable of storing electrical energy. When encased in a container and provided with electrical terminals, the cell is the basic "building block" of a battery. Although the capacity of the cell is determined by its size, the cell's voltage is strictly a function of the basic electrochemistry of the couple.

Cell Reversal

Reversing of polarity of terminals of a cell in a multi-cell battery due to over discharging.

Charge

Return of electrical energy to a battery.

Charge Acceptance

Willingness of a battery or cell to accept change. May be affected by cell temperature, charge rate and state of charge.

Charge Efficiency

Value obtained when the increase in dischargeable capacity of the battery is divided by the current input. A measure of charge acceptance. Also indicates

传统的UPS蓄电池测试维护手段

一般UPS电源对电池的要求：满足一定的端电压；电池应具有在启动放电瞬间就能输出大电流的特性；满足一定的容量，以保证逆变供电的时间。

1、用万用表测量电池的端电压

实践证明，用万用表测量UPS电池的浮充端电压是无法判定旧电池是否已经失效。所以一般要离线或在线测量电池的端电压，被测电池的端电压为12V左右（对12V电池而言），最低不能低于10.5V。不足10.5V的电池即为欠压或已经失效的电池。若这种电池在经过充电或激活充电后端电压仍达不到12V，即为失效电池。

2、测试UPS电池是否具有启动瞬间输出大电流的特性

后备式UPS不间断电源由市电供电向逆变供电的切换时间要求小于7ms,一般设计为4-5ms左右。这就是说，一旦市电供电中断，UPS电池必须在小于4-5ms时间内输出负载所需的电流。有些失效的电池能够满足端电压和容量的要求，但不能在少于4-5ms内放电电流达到大电流的要求，也是不合格电池。UPS电池瞬间输出大电流的特性只有在关闭市电才能测试，在不知道电池性能情况下有一定的风险，一般是不进行的。

3、判别UPS电源电池的容量

传统判别UPS电源蓄电池容量的方法与判别一般蓄电池的方法一样，将整组蓄电池组脱离通信电源系统并上电阻丝，以八或十小时率恒流放电，然后以最先到达放电终止电压的某一单体蓄电池的放电时间与电流，来推算其容量。
