How much fault occurs when the UPS power supply is used for a long time, and the statistics of UPS maintenance work. Reserve UPS power supply is 50% due to battery triggers. Online UPS power supply is reasonable for designing circuitry, the balance taken by the drive power component capacity, so the power supply circuit is very low, and there is a battery failure rate of 60%.

Therefore, the correct use of maintaining the life of the UPS battery is one of the key factors that reduce the failure of uninterruptible power supply. Method 1 of reducing UPS power battery failure 1. Regularly check the end voltage and internal resistance of each unit battery periodically.

For 12V unit cells, if the end voltage between each unit battery is found to exceed 0.4V or more than 80MΩ or more, the unit cell should be balanced to restore the battery within the battery. Resistance and eliminating the end voltage between each unit battery.

充电时充电电压需13.5~13.8V。

Most batteries that have a good balance charging process can restore their internal resistance to 30MΩ. During operation, the UPS power supply is eliminated due to the above-described imbalance of each unit battery characteristics, which is impossible to rely on the charging circuit inside the UPS power supply, so that this characteristic has a significantly unbearable battery. Group, if the offline is not charged in time, its unevenness will become more and more serious.

2. Re-floating the UPS power downtime for more than 10 days, before rebooting, the UPS power supply should be started under the conditions that do not load the load to re-use the charger product electrical circuit to re-carry the battery to the battery 10 to 12h. run.

UPS电源处于浮充状态，没有放电过程，相当于“储能”状态。 If this state is too long, the battery has not been scrapped due to "long-term storage", which is mainly manifested as the increase in battery internal resistance, and the internal resistance can reach a few Ω.

We found that after 2 months of room temperature, the battery can be used for about 97% of its rated value. If the storage is 6 months, its use capacity becomes 80% of the rated capacity. If the storage temperature rises, its use capacity will decrease.

It is therefore recommended that the user is best to unplug the mains input every 20 ° C, so that the UPS power supply is operated by the battery to provide energy to the inverter. 但此操作不宜过长，且在负载达到30%左右即额定输出的30%左右时，即可放电。 How to reduce the failure of the UPS power battery 3.

Reduce the service life of deep discharge electricity is closely related to the depth of it is discharged. UPS电源的负载越轻，其蓄电量与其额定容量之比就越大，这种情况下，由于电池电压过低而导致自动关机的现象比较多，放电深度也比较深。 How does the actual process reduce the battery in depth? Method is simple: When the UPS power supply is in the middle of the electric power supply interruption, most of the UPS power supplies will be around 4s at the gap 4S when the UPS power supply is powered by the electric power supply.

Periodic alarm sound, notifying the user that now is the battery. When he heard the alarm sound is urgent, the power supply is already in depth, and should immediately perform emergency treatment, close the UPS power supply. 不要强迫，一般不要让UPS电源一直工作到电池电压过低而自动关机结束。

4. Using the high peak charging of the power supply to the UPS power supply for a long time in the market, low-voltage power supply or frequently-stopped power, to prevent the battery from being damaged by the long-term charging, it should be fully utilized to charge the battery to the battery. Ensure that the battery has sufficient charging time after each discharge.

一般电池放电后要充电至额定容量的90%至少需10～12h。 Note that the charger's selection UPS power supply-free seal battery cannot be charged with a controlled silicon type "fast charger". 这是因为这种充电器会导致电池处于“瞬间过流充电”和“瞬间瞬时充电”的恶劣充电状态。

这种状态会使电池的电量大大下降，严重的时候电池就会报废。 When using the UPS power supply of the constant voltage cut-off charging circuit, be careful not to adjust the battery voltage too low protection work points, otherwise, it is prone to overflow charging in its initial charging. 当然最好用既有恒流，又有恒压的充电器。

5. Ensure that the capacity of the power supply ambient temperature battery is closely related to the ambient temperature. 一般来说，电池的性能参数都是在室温为20℃的情况下标定的，当温度低于20℃时，其储电容量会有所降低，而温度高于20℃时，其可供使用的容量会略有增加。

不同车型不同型号温度升高的程度也不同。 据统计，在-20℃时，电池的容量只能达到标称容量的60%左右。 可见温度的影响不容忽视。
