UPS battery and common sense of battery use

Tags: UPS battery and common sense of battery usage UPS is called uninterruptible power supply, because when power is cut, it can quickly switch to 'inverter' state, so that the computer in use will not be lost due to sudden power failure and storage in the future. Important documents. It is not used as a backup power source. If you just want to use electricity when the power is out, just buy an inverter. Generally, maintenance-free lead-acid batteries are mostly used in household UPS. Common sense of UPS battery usage 1. UPS battery charging 1. When UPS battery float charging, please use charging voltage 2.275V/single cell (set value at 20℃) for constant voltage charging or current below 0.002CA. Current charging. When the temperature is below 0C or above 40C, it is necessary to correct the charging voltage. With 20C as the starting point, for every degree change, the single cell voltage changes -3mv. When the UPS battery is cyclically charged, the charging voltage is 2.40-2.50V/single cell (the set value at 20°C), and the constant voltage voltage is charged. When charging at a temperature below 5C or above 35℃, start at 20℃, and adjust the charging voltage to -4mv/cell for every degree of change.　　The initial charging current is controlled below 0.25CA.　　 The charging capacity is set to 100-120% of the discharge capacity, but when the ambient temperature is below 5C, it is set to 120-130%.　　The lower the temperature (below 5C), the longer the charging end time, and the higher the temperature (above 35C), the more likely it is to overcharge. Therefore, it is better to charge within 5C～30C especially when it is recycled.　　 In order to prevent overcharging, try to install a charging timer or automatically switch to trickle charging.　　 The UPS battery temperature should be controlled within the range of -15C～+40C during charging. 2. When discharging the UPS battery, please control the battery temperature within the range of -15℃- +50℃.　　 Please control the continuous discharge current below 3CA (H control below 6CA).　　The end-of-discharge voltage varies according to the magnitude of the current, and it is roughly as follows. When discharging, the voltage should not be lower than the following voltage.　　 Please charge quickly after discharging. If you accidentally over-discharge, please charge it immediately. Discharge current discharge termination voltage 0.2CA less than 1.75CA/single cell 0.2CA or more 0.5CA less than 1.70CA/single cell 0.5CA or more 1.0CA less than 1.55CA/single cell 1.0CA or more 1.30CA/single Grid UPS battery 3. Installation precautions When installing the UPS battery storage battery, please be sure to observe the following: 　　1.1 Do not install UPS batteries in a sealed space or near a fire, otherwise there is a danger of explosion and fire.　　1.2 Do not cover the accumulator with vinyl films that may cause static electricity. When static electricity is generated, it may cause an explosion.　　1.3 Do not install batteries where water may enter, otherwise there is a risk of electric shock or fire.　　1.4 Please do not install the battery in an environment exceeding -40 °C~60 °C.　　1.5 Do not use the battery in a dusty place, otherwise it may cause a short circuit of the battery.　　1.6 When putting the battery into the box, pay attention to air circulation.　　1.7 Do not press the upper cover with sticky or label-like objects. Because there is an exhaust valve under the upper cover, the gas generated in the battery will not escape. 1. 8 Number of parallel connections-During floating charging, the plug-in terminal battery can only be associated with three rows at most. There is no special restriction on the bolt-fastened terminal, but the number of parallel connections is small and the reliability increases. In addition, when connecting in parallel, it is necessary to consider equalizing the wiring conductor and contact resistance between the columns. In order to keep the charge and discharge batteries in each column balanced, please do not exceed three columns in actual use.　　1.9 When using batteries with different capacities, new and old, and different manufacturers at the same time, due to their different characteristic values, the UPS battery and the machine may be damaged, so please avoid using them. Four, UPS battery storage 　　1. When storing, please be careful not to exceed the temperature range of -20℃～+40℃　　2. When storing UPS batteries, they must be stored in a fully charged state. Since a part of the capacity will be lost due to self-discharge during transportation or during the storage period, please recharge it when using it.　　3. When storing for a long time, to make up for the self-discharge during storage, please charge it up. When stored under the condition of over 40C, it will have a bad influence on the battery life, please avoid it!　　4. Store in a dry, low-temperature, well-ventilated place. 5. If the battery packaging is accidentally wetted by water during storage or transfer, the packaging carton should be removed immediately to prevent the water-soaked carton from becoming a conductor causing the UPS battery to discharge or burn out the positive terminal. 5. About daily inspection and maintenance of UPS batteries 1. Check the battery regularly. If you find any external pollution such as dust, please clean it with a cloth soaked in water or warm water. Do not use gasoline, banana water and other organic solvents or oils for cleaning, and avoid using chemical fiber cloth. 2. During floating charge, when the total voltage of the UPS battery or the indicator value of the voltmeter on the indicator panel deviates from the reference value shown in the table below (±0.05V/single cell), the cause should be investigated and dealt with.
