机房内部的天力蓄电池长期闲置不用或使天力 蓄电池长期处在浮充状态而不放电，会导致天力 蓄电池中大量的硫酸铅吸附到天力 蓄电池的阴极表面，形成所谓的电池阴极板的“硫酸盐化”。由于硫酸铅是一种绝缘体，它的形成必将对天力 蓄电池的充放电产生极不好的影响，因为在阴极板上形成的硫酸盐越多，天力 蓄电池的内阻越大电池的可充放电性能越差，从而导致天力 蓄电池“老化”、“活性”下降，使天力 蓄电池的使用寿命大大缩短。应该每隔3到4个月人为地通过中断市电或通过软件/硬件控制手段将UPS的整流器/充电器置于关闭状态让UPS中的天力 蓄电池放电。对于这种为“激活”天力 蓄电池而进行的电池放电操作，它的放电时间以控制在正常放电时间的1/3、1/4为宜。
If the Tianli battery in the machine room is not used for a long time or the battery is floating for a long time without discharging, a large amount of lead sulfate in the battery will be adsorbed on the cathode surface of the battery, forming the so-called "sulfation" of the cathode plate of the battery. As lead sulfate is an insulator, its formation will have a very bad impact on the charge and discharge of Tianli battery, because the more sulfates are formed on the cathode plate, the greater the internal resistance of Tianli battery, the worse the charge and discharge performance of Tianli battery, which leads to the "aging" and "activity" decline of Tianli battery, and greatly shortens the service life of Tianli battery. The Tianli battery in the ups shall be discharged manually by interrupting the power supply or by software / hardware control means every 3 to 4 months. For this kind of battery discharge operation for "activating" Tianli battery, its discharge time should be controlled at 1 / 3 and 1 / 4 of the normal discharge time.
