NorthStar UPS Quick Start Guide Unpacking the Batteries the negative (-) post of one battery is adjacent to the positive (+) post of the next adjacent battery. When received, the batteries should be inspected. Make sure the batteries were not damaged during 6.
Introduction the voltage should be increased by 2 mV/cell/°C. The graph below shows values for an individual cell. 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.
The table above shows the time needed to recharge Ripple Current following a 100% DOD cycle, depending on the maximum charge current available. If the DOD is less Unacceptable levels or ripple current from the charger than 100%, the total recharge time will be less. To or the load can have a major impact on battery internal prevent overcharge, the duration from T1 to T2 (i.e.
Cold Temperature Performance As seen in the above graph, the batteries design life will vary significantly due to differences in discharge rates Colder temperatures can prolong battery life because and environmental temperatures. corrosion processes within the positive plates of the battery slow down as the temperature decreases.
Battery Safety Keep away from open flames For full information please read the Safety Data Sheet In case of accidental overcharge, a flammable gas can (SDS). The SDS document is titled SDS-430-00607 leak from the safety vent. Discharge any possible static and can be downloaded from the internet at www.
The second is on the right hand side towards the rear of Don’t the battery (see picture below). • Never drag a battery along the floor. Doing so could cause damage to the battery case leading to leakage of electrolyte and damage to equipment. •...
10.6 Security Shelf Life All installation and ventilation must comply with the current federal, state and local regulations. NorthStar batteries have a two year shelf life at +25° C (+77°F). 10.7 Putting the Batteries in Place Commissioning/Installation NorthStar battery racks or cabinets are recommended for proper installation.
