What are the technical parameters of UPS lead-acid batteries?

UPS lead-acid battery technical parameters UPS lead-acid battery is one of the most important equipment in energy storage power station. The cost accounts for about 80% of the system. The technical parameters of the battery are very important to the system design. Let’s take the lead-carbon lead-acid battery as an example. The key parameters of the battery such as capacity, depth of discharge, number of cycles and so on. When selecting and designing the battery and inverter, pay attention to the maximum charge and discharge current of the battery. 1. Battery capacity The capacity of the UPS battery is determined by the amount of active material in the battery, usually expressed in Ah or mAh. For example, the nominal capacity of 250Ah (10hr, 1.80V/cell, 25°C) refers to the discharge capacity at 25°C with a current of 25A for 10 hours to reduce the voltage of a single battery to 1.80V. 2. Rated voltage The potential difference between the positive and negative poles of the UPS battery is called the rated voltage of the battery. Common lead-acid batteries have three rated voltages of 2V, 6V, and 12V. The single lead-acid battery is 2V, and the 12V battery is made up of 6 single batteries in series. 3. The maximum charge and discharge current UPS lead-acid batteries are bidirectional. There are two states, charging and discharging. This current is limited. Different batteries have different maximum charge and discharge currents. The battery charging current is generally expressed as a multiple of the battery capacity C. For example, if the battery capacity Cu003d100Ah and the charging current is 0.15C, it is 0.15100u003d15A.
