Lead Calcium Grids
The heavy duty lead calcium alloy grids provide an extra
margin of performance and life in both cyclic and float
applications and give unparalleled recovery from deep
discharge.
Long Cycle Service Life
Depending upon the average depth of discharge, over a
thousand discharge/charge cycles can be expected.
Float Service Life
The expected service life is five years in float standby
applications.
Separators
The use of the special separator material provides a very
efficient insulation between plates preventing inter-plate
short circuits and prohibiting the shedding of active
materials.
Long shelf Life
The extremely low self discharge rate allows the battery to
be stored for extended periods up to one year at normal
ambient temperatures with no permanent loss of capacity.
Operating Temperature Range
The batteries can be used over a broad temperature range
permitting considerable flexibility in system design and
location.
Charge – 15°C to 50°C
Discharge – 20°C to 60°C
Storage – 20°C to 50°C (fully charged battery)
