There
is practically no float service condition in India.
All the applications are cyclic , often to even 70%
depth of discharge. Most of the installations are in
non-A/c rooms where the ambient temperature can go to
45 deg C.Barring few cities, average power failure is
2 to 3 hours a day. In semi-urban & rural areas,
it is as high as even 10 hours a day.
Even “Quality” of power is highly questionable
in many areas including the capital city, puts VRLA
batteries under very arduous charge - discharge cycles
without adequate recharge.Few organized system manufacturers
leaving us to operate with power systems with far less
reliability. Average time taken for installation can
vary from 2 months to 9 months & VRLA battery should
be capable of delivering 100% capacity in 1st cycle
after such prolonged storage under high temperatures. |
