Features
Long Service Life - Thick plate design and ef cient gas
recombination yield a service life expectancy of up to 10 years in
standby mode.
Low Internal Resistance - Superb high-rate discharge
characteristics ensure reliable performance in UPS and Telecom
applications.
Maintenance-Free, Non-Spillable - Proven VRLA technology
guarantees safe operation without maintenance and ‘non-
restricted article’ status for transportation.
Low Self-Discharge - Lead-calcium alloy grids and use of high
purity lead account for superior shelf-life characteristics permitting
storage for extended periods of time.
Designed-In Reliability - Cutting-edge manufacturing and
process control combined with meticulous quality assurance
procedures guarantee consistent and dependable performance.

Charging
Cycle Applications: Limit initial current to 8.4A. Charge until battery voltage
(under charge) reaches 14.4 to 14.7 volts at 68°F (20°C). Hold at 14.4 to 14.7
volts until current drops to under 280mA. Battery is fully charged under these
conditions, and charger should be disconnected or switched to “oat” voltage.
“Float” or “Stand-By” Service: Hold battery across constant voltage source of
13.5 to 13.8 volts continuously. When held at this voltage, the battery will seek its
own current level and maintain itself in a fully charged condition.
Note: Due to the self-discharge characteristics of this type of battery, it is
imperative that they be charged within 6 months of storage, otherwise permanent
loss of capacity might occur as a result of sulfation.
Chargers
Power-Sonic offers a wide range of chargers suitable for batteries up to 100AH.
Please refer to the Charger Selection Guide in our specication sheets for “C-Series
Switch Mode Chargers” and “Transformer Type A and F Series”. Please contact our
Technical department for advice if you have difculty in locating suitable models.

Charging is not
necessary unless
100% of capacity
is required.
Charging before
use is necessary
to help recover
full capacity.
Charge may fail
to restore full
