What reasons and practical methods affect the life of the Naipu battery

⑴The impact of ambient temperature on the battery greater impact. If the ambient temperature is too high, the battery will be overcharged to generate gas, and if the ambient temperature is too low, the battery will be undercharged, which will affect the battery life. Therefore, it is generally required that the ambient temperature be around 25 °C, and the value of the UPS floating load voltage is also set according to this temperature. In actual use, Naipu batteries are generally charged within the range of 5°C to 35°C. Lower than 5°C or higher than 35°C will significantly reduce battery capacity and shorten battery life.


⑵ Unload the impact of depthon the Naipu battery life is also very large. The deeper the battery\'s depth of discharge, the shorter the cycle times, so deep discharge during use should be avoided. Of course, the UPS has the function of battery low potential protection. In general, the UPS will automatically shut down when a single battery discharges to about 10.5 V. However, if the UPS is discharged under light load or no load, it will also cause a deep discharge of the battery.


⑶Battery during during storage, transport and installation, part of the capacity is lost through self-discharge. Therefore, before it is put into use after installation, the remaining capacity of the battery should be judged according to the open-circuit voltage of the battery, and then different methods should be used to charge the battery.j to complete. For Yuasa batteries placed in standby, additional charging must be stopped every 3 months. The quality of the battery can be judged by measuring the open circuit voltage of the battery. Taking a 12 V battery as an example, it means that if the no-load voltage is higher than 12.5 V, the battery\'s energy storage is more than 80%. If the open-circuit voltage is less than 12.5 V, additional charging must be stopped immediately . If the no-load voltage is less than 12V, it means that the battery stores less than 20% of the electrical energy and the battery cannot be used.


⑷The loading and battery discharge current is generally represented by C, and the actual value of C is related to the battery capacity. For example, for a 100AH ​​battery, C=100A. The maximum charging strawom of Naipu lead-acid maintenance-free battery is 0.1 About C, the charging current cannot exceed 0.3 C. If the charging current is too large or too small, it will affect the battery life. The discharge current is generally required to be between 0.05 C and 3 C. UPS can meet this requirement under normal use, but it should also prevent unexpected situations such as battery short circuit, etc.

⑸Charge voltage. Because the UPS battery is a backup working mode, the mains is in the state of charge under normal circumstances and will only be discharged when there is a power failure. To extend battery life, the UPS generally uses the chargerin common the control method of constant voltage and current limiting. After the battery is fully charged, it will turn into a floating charge state. The floating charge voltage of each cell is set to about 13.6V. If the charge voltage is too high, the battery will be overcharged, otherwise the battery will be overcharged. Insufficient charging. Abnormal charging voltage can be caused by battery misconfiguration or charger malfunction. Therefore, when installing batteries, pay attention to the correct battery specifications and quantities, and do not mix batteries with different specifications and batch numbers. do not use inferior external chargers and consider heat dissipation when installing. To further extend battery life, advanced UPSs currently use a three-stage ABM (Advanced Battery Management) intelligent battery management plan, i.e. charging is distributed during the first chargethere are three phases of floating charging and rest: the first phase is constant current balance charging, charging the battery capacity to 90%; the second stage is floating charging, which charges the battery capacity to 100% and then stops charging; the third stage is natural discharge, in this stage, the battery uses its own leakage to discharge the electricity until it reaches the lower limit of the specified voltage, and then repeats the above three stages. This method has changed the previous full charge, and still keeps the battery in a trickle charge state 24 hours a day, extending the life of the Naipu battery.
