SEALED MAINTENANCE FREE
The valve regulated, spill-proof construction of the POWER-SONIC battery
allows trouble-free, safe operation in any position. There is no need to
add electrolyte, as gases generated during charging are recombined in a
unique "oxygen cycle".
No special handling precautions or shipping containers - surface or
air - are required due to the leak-proof construction.
LONG SERVICE LIFE
Under normal operating conditions, four or five years of dependable
service life can be expected in stand-by applications, or between 200 and
1000 charge/discharge cycles depending on the average depth of discharge.
Batteries may be used in series and/or parallel to obtain choice of
voltage and capacity. Due to recent design breakthroughs, the same battery
may be used in either cyclic or standby applications. Over 50 models are
available to choose from.
The high-impact resistant battery case is made either of non-conductive
ABS plastic or styrene. Large capacity batteries frequently have polypropylene
cases, all of these materials impart great resistance to shock, vibration,
chemicals and heat.
HIGH DISCHARGE RATE
Low internal resistance allows discharge currents of up to ten times
the rated capacity of the battery. Relatively small batteries may thus
be specified in applications requiring high peak currents.
LONG SHELF LIFE
A low self-discharge rate may allow storage of fully charged batteries
for up to a year at room temperature before charging is required. Lower
storage temperatures enhance shelf life characteristics even further.
WIDE OPERATING TEMPERATURE RANGE
Power-Sonic batteries may be discharged over a temperature range of
-40 ºC to +60 ºC (-40 ºF to +140 ºF), and charged at
temperatures ranging from -20 ºC to +50 ºC (4 ºF to +122
DEEP DISCHARGE RECOVERY
Special separators, advanced plate composition, and a carefully balanced
electrolyte system have greatly improved the ability of recovering from
excessively deep discharge.
