韓國(guó)KOBA蓄電池MF135F51  12V130AH高性能鉛酸UPS電源The Korean KOBA Battery MF210H52/12V200AH starter Koba Deep Cycle HD Plus battery adopts an anti vibration design and is suitable for harsh marine, RV, 4WD, and heavy-duty vehicle applications. The HD PLUS series provides high durability in deep cycle services, and due to its * * * self discharge characteristics, it can be safely stored for longer periods of time.

Koba deep cycle batteries are a type of * * * * or "indoor" battery. Having the ability to cycle and start, it is an ideal battery for various marine and vehicle applications. The current of the battery pack is 40KVA/384V=104A, so a 50mm2 cable is selected for the battery connection.

Total number of batteries=(power/DC voltage * hour)/Ampere hour per block * number of blocks per group

Battery temperature affects battery reliability

Temperature has a significant impact on the natural aging process of batteries. Detailed experimental data shows that for every 5 degrees Celsius increase in temperature, the battery life decreases by 10%, so the design of UPS should keep the battery as warm as possible. All online and backup/online hybrid UPS generate more heat during operation than backup or online interactive UPS (so the former requires the installation of fans), which is also an important reason for the relatively long battery replacement cycle of backup or online interactive UPS.
