The article describes the results of testing a Ben-ning AC/DC power supply, with integrated NIT TBA-ST meter. Such integration enables accurate and energy-efficient measurements of available capacity of individual 48-voltage VRLA/AGM batteries with remote management possibilities. The full compliance with the requirements for telecommuni-cation pow...
Article
Full-text available
The article presents numerous problems with standby batteries used in telecommunications systems, with a particular emphasis placed on the assessment of their real capacity. The methods used to evaluate the technical condition of batteries and to measure their real capacity are presented. Also, the a new test device which measures the actual batter...

... Therefore, to clearly determine the actual capacity, it is best to discharge the battery with 10hour current, i.e. 0.1CA. After discharging, to maintain the best condition, the battery should be immediately fully charged -preferably with a current close to 0.1CA (maximum -2 times more or 2 times less) [17]. The result of the test is the real capacity Q expressed in amperehours (Ah) and the percentage of nominal capacity (Q =% C), but you can also measure the number of watt-hours (Wh) received (it is also useful). ...
... Source documents [11,12,13,14,15,8,10] and own research allow to create this description of the component functions of a modern telecommunication AC / DC power system. ...
