With the demand of the market, the UPS uninterruptible power supply is widely used in various industries. The UPS battery has become an important part of this system. No battery-free UPS can only be called regulated running frequency. The advantages and disadvantages of the battery are directly related to the extent of the entire UPS system. Regardless of the UPS design, how well is full, once the battery is invalid, the UPS can not provide uninterruptible power supply. In a UPS system, there are mostly valve-free sealing-free maintenance batteries.The maintenance-free maintenance here is just compared to the ordinary battery, exempting the addition of pure water or distilled water, adjusting the work of the electrolyte liquid, is not eliminating maintenance. Instead, in order to achieve uninterruptible power supply of UPS, we must maintain and maintain lead-acid storage batteries more detachably. The following describes the UPS battery detection and what should be noted in daily maintenance.
1. Detection of the battery
The battery's good decision is determined by the battery measuring instrument, but the general user has few such instruments, only one multimeter. Decision of several summary of the batteries in the following maintenance for reference.
1) Judgment from the appearance: Observing the appearance, protruding, leakage, cracking blow, charring, screw connection, etc.
2) Load measurement: If the appearance is abnormal, the UPS operates in battery mode, and if the discharge time is significantly shorter than normal discharge time, after 8 hours, it is not possible to return to normal alternate times, and determine the aging of the battery.
3) Measurement with multimeter:
a. Measurement in battery discharge mode: Measure the respective battery terminals in the battery pack, if one or more battery end voltage is revealed above or lower than the nominal voltage (nominal voltage 12 V / section), determine the battery aging.
b. Under the main mode: the charging voltage of each battery terminal in the battery pack, if the charging voltage of one or more batteries is obvious above or lower than its * he voltage, the battery aging is determined.
c. Measure the total voltage of the battery pack: The total voltage of the battery pack is significantly lower than the nominal value. After 8 hours of charging, it cannot return to the normal value, even if it is restored to the normal value, the discharge time does not reach the normal discharge time, determine the aging of the battery.
d. Battery boot measurement: UPS does not boot, do not pick up the market, first measuring whether the battery pack has the total voltage of the battery pack within the rated range, do not leave, always focus on the instructions of the Worksheet, then connect the machine key, if this When the battery total voltage is lowered to the low voltage protection value or even lower, the UPS is automatically turned off immediately, and the voltage is immediately returned to the original value. Determination of battery aging.
2, battery maintenance
1) The ambient temperature affects the battery. The ambient temperature is too high, which will affect the battery life; the ambient temperature is too low, which reduces the capacity of the battery. It is recommended that the battery is used under temperature conditions + 5 ¡ã C ~ +30 ¡ã C (suitable for 25 ¡ã C).
2) Different capacity, different new and old batteries are strictly prohibited;
3) The battery should be installed as much as possible in clean, cool, ventilated, dry, to avoid the effects of sunshine, heater or its * his radiation heat source.
4) The battery is stored, transported, and the part capacity will be lost due to self-discharge, so before installation, the residual capacity of the battery should be determined according to the battery's open circuit voltage, and then supplement the battery.

5) UPS During operation, pay attention to monitor the end voltage value of the battery pack, a floating current value, a voltage value of each battery, a battery pack, and a pair of insulating states of the battery pack and the DC bus.
6) After the battery is discharged, it should be charged in time, and the battery is discharged, which causes the battery capacity or even damage, so the appropriate charger is configured;
7) Appropriate discharge, helps the battery activation, such as long-term non-stop power, should discharge the battery, 2 ~ 4 times a year, can use existing load discharge, time is 1/4 ~ 1/3 backup time ;
8) The deeper the battery discharge, the less the number of cycles used, and the discharge should be avoided during use. If the UPS is in a light discharge or no-load discharge, the battery will also cause discharge of the battery.
9) Long-term disabled battery should be stored after being charged, and the battery needs to be charged and discharge every six months, and the battery is generally floated for about 4 to 10 hours, and working in the battery inverter 2 to 3 minut Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
