Development of long-life small-capacity VRLA battery without dry-out failure in telecommunication application under high temperature environment

In this paper, a power monitoring system intended for verifying backup lead-acid batteries parameters such as voltage level, battery temperature and charge capacity is developed. Such system is capable of doing the following: 1) switching between available bad and good conditioned lead-acid batteries without interrupting power service, 2) automatic charging of lead-acid batteries, 3) integrate a power/demand analyzer for determining appropriate power rating before switching lead-acid batteries. The setup experiment consists of five 6V (4Ah for 10 hours) and five 12V (5Ah for 10 hours) lead acid batteries which can be configured indifferent series or parallel connections and various lighting loads. Experiments show successful switching between batteries without power interruption, lead-acid parameter monitoring and automatic charging.
