    1 introduction ups batteries from northstar battery (nsb) compa- ny provide excellent high-rate discharge and recharge performance for mission critical applications. Ab- sorbed-glass-microfibre (agm) technology is utilized, which means the electrolyte is fully absorbed in a very fine glass mat. This...

    The table above shows the time needed to recharge following a 100% dod cycle, depending on the maximum charge current available. If the dod is less than 100%, the total recharge time will be less. To prevent overcharge, the duration from t1 to t2 (i.E. The time at 2.41 volts/cell) should always be l...

    3.3 cold temperature performance colder temperatures can prolong battery life because corrosion processes within the positive plates of the battery slow down as the temperature decreases. Unfortunately, lower temperatures also lower the capacity of lead-acid batteries. As battery temperature drops b...

    Since the batteries are supplied charged, storage time is limited. During storage, lead-acid batteries will gradually self-discharge. The rate of self-discharge increases with increasing temperature. As a result, maintenance charging needs to be performed more frequently at higher temperatures. In o...
