Special battery in the installation should pay attention to what matters

The UPS power supply is called an uninterrupted battery, because it can be quickly converted to "inverter" when the power is cut off, so that the computer will not be used in the future because of sudden power failure and storage and the loss of important documents. Is not used as a backup power supply, if you just want to be able to use electricity when the power outage, the light is enough to buy the inverter. General household UPS used in most of the special maintenance free lead-acid battery. Special accumulator is UPS power supply is used as the device that stores electric energy, it is made up of a few special batteries in series, its size decides its maintain discharge (power supply) time.
General backup, online interactive or backup / ferromagnetic UPS will not ripple current, the other design of UPS will produce ripple current of different sizes, depending on the specific design methods. Just check the UPS structure to know if the UPS can generate ripple current. If the online UPS battery is between the charger and the inverter, the battery will have ripple current, which is the common "double conversion" UPS. If the battery is separated from the inverter with a cut-off diode, relay, transformer or rectifier, there will be no ripple current in the ups battery. Of course, this design of UPS is not always "online", so this UPS is called "hybrid backup / online" UPS.
Special battery is the most unreliable part of the UPS system, but the UPS is designed to have a direct impact on the reliability of the battery. Let the UPS battery has been maintained state (even if the UPS shutdown) can extend the life of the battery, try to avoid the use of high battery voltage UPS. Some UPS design will make the battery ripple current, resulting in unnecessary overheating of the battery. Most of UPS's extraordinary batteries are similar, but the difference in UPS design can greatly affect the life of the battery.
