1.Normally, the battery should be charged and discharged every 3-6 months, and the charging time of the standard machine should not be less than 10 hours after discharge.
2.UPS should be charged every 3-6 months if it is not in use for a long time.
3. The battery usage environment requires a temperature between 0 ℃ and 40 ℃, avoiding direct sunlight and keeping it clean.
4. Generally, under room temperature conditions, the float charging service life of sealed maintenance free lead-acid batteries during normal use is 3-5 years.
Can UPS use water filled batteries?
Sure, but it is recommended that users use maintenance free batteries. Because there may be factors such as users forgetting to add water, battery acid water dripping out, or poor battery gas emissions during use, which can cause battery necrosis or affect the normal operation of UPS loads. In addition, the charger of APC UPS is designed for the characteristics of lead-acid batteries, so it is not suitable for other types of batteries.
What is the configuration of UPS backup battery?
Due to the correlation between battery discharge time and multiple factors such as discharge current, ambient temperature, load type, discharge rate, battery capacity, etc., the actual discharge time cannot be directly derived using a formula. We now provide the formula for the maximum discharge current of the battery:
I=（Pcosφ）/（ηEi）
——Where P is the nominal output power of UPS;
——Cos φ is the load power factor, PC、 The server generally takes 0.6~0.7;
——η is the efficiency of the inverter, usually taken as 0.8;
——Ei is the final discharge voltage of the battery, generally referring to the voltage of the battery pack.
By substituting specific data into the above equation and calculating the maximum discharge current of the battery, the corresponding discharge time can be found from the relationship graph between discharge current and discharge time at various temperatures of the battery. Please note that the calculated value here is the total discharge current of the battery. When multiple sets of batteries are connected externally, it is necessary to obtain the discharge current value of a single set of batteries.
Can UPS use rechargeable batteries?
There are two situations for this issue: one is that the user needs APC monitoring software. In this case, the battery parameters displayed by the monitoring software may differ from the actual situation after using alkaline batteries. This will cause difficulties for users to use. Secondly, users do not use APC software. Due to the significant difference in discharge characteristics between alkaline batteries and acidic batteries. The time from battery discharge to alarm point (UPS beeps every second) to UPS automatic shutdown is very short, and users must pay special attention during use; In addition, alkaline batteries usually require liquid addition (usually every two years), which is inconvenient for users to use.
