Capacity performance of VRLA battery and automotive battery for energy backup in telecommunication access / Nurhayati Abd Halim

Abd Halim, Nurhayati (2011) Capacity performance of VRLA battery and automotive battery for energy backup in telecommunication access / Nurhayati Abd Halim. [Student Project] (Unpublished)

Abstract

This study will show the capacity performance of valve-regulated lead acid (VRLA) battery and starting, lighting, ignition (SLI) or also known as automotive battery in telecommunication access outdoor cabinet. The capacity performance will show the efficiency of battery capacity applied to VRLA and automotive battery using capacity test with constant current. The method to determine the failure condition due to undercharge and overcharge condition is done at three telecommunication outdoor cabinets at Bangi, Selangor. During this study, relationship between voltage and temperature is important to decide whether it is undercharge or overcharge condition. Besides that, the temperature of battery is very important to control the charging voltage to prevent thermal runaway that can lead to decrease the battery life.
