On each monobloc/cell the positive terminal is identif ed by a
“+” symbol. Install the batteries in accordance with the
instructions and/or layout drawing, taking care to ensure
correct terminal location and polarity.
Connect the blocs/cells with the connectors and fasteners
provided. Tighten the fastener set bolt(s) / nut(s) to the
fastening torque level indicated on the product label.
Place the insulating covers in position immediately after
tightening the fasteners.

monoblocs and cells
retain the long f

traditional

SBS monoblocs and cells with the
added benef

and fast charge modes.
4.1 Stand by / Float Operation
Constant voltage chargers are recommended. The charging
voltage should be set at the equivalent of 2.29Vpc at 20°C/68°F
or 2.27Vpc at 25°C/77°F.
Operation at temperatures higher than 20°C will reduce life
expectancy. Life is reduced by typically 50% for every 10°C rise
in temperature. To offset the impact of higher temperatures
compensation to the f oat voltage should be applied.
The recommended f oat voltage temperature compensation is:
Due to the very low internal resistance,
SuperSafe
SBS EON
monoblocs and cells will accept unlimited current during
recharge but for cost and practical purposes in f
oat
applications where recharge time to repeat duty is not critical,
the rectif
er current can be limited to the load plus 0.1C
10
Amps.
4.2
Cyclic Operation
In addition to the long life characteristics inherent in
traditional
SuperSafe
SBS TPPL designs, EON Technology has
been
developed to provide high performance in applications
where
the battery is subjected to repeated cyclic duty or
where
power reliability is tested by high temperatures and
harsh
conditions combined with remote locations.
In cyclic applications the charging voltage should be set at the
equivalent of 2.40Vpc cell at 20°C/68°F, with the rectif er
current limit set to a minimum of 0.1C
10
A (EON Technology is
designed to accept unlimited in rush currents without causing
damage to the internal electro chemistry).
The optimal cyclic performance is achieved by returning the
battery to full state of charge between discharge cycles. It is
possible to operate SBS EON Technology monoblocs and cells
in partial state of charge condition, however, in such situations
it is very important to ensure that the battery is periodically
returned to full state charge to maintain battery state of health.
It is recommended to contact your EnerSys
®
representative to
obtain additional information and guidance for such psoc
applications.
In systems where control of charge factor is not possible, it
may be possible to estimate time to full state of charge by
using the calculation:
Recharge time (hrs) = 2* ((0.8 x discharged Ah) / current limit) +1
The recommended compensation for charge voltage in cyclic
applications is:
5. Maintenance
In practice, the user usually specif es the maintenance
schedule based on site criticality, location and manpower.
However, the following may be used as a suggested
maintenance schedule.
• Monthly (record all readings)
Measure the battery string voltage. If necessary, adjust the
f oat voltage to the correct value.
• Every six months (record all readings)
Measure the battery string voltage. If necessary, adjust the
f oat voltage to the correct value.
Measure individual bloc/cell voltages. The blocs/cells
should be within 5% of the average.
Inspect for contamination by dust, loose or corroded
connections. If necessary isolate the string/bloc/cell and
clean with a damp soft cloth. Warning - Do NOT use any
type of oil, solvent, detergent, petroleum-based solvent or
ammonia solution to clean the battery containers or lids.
These materials will cause permanent damage to the
battery container and lid and will invalidate the warranty.
Contact EnerSys

if you have any questions regarding
maintenance.
6. Disposal
SuperSafe
SBS EON Technology batteries are recyclable.
Scrap batteries must be packaged and transported in
accordance with prevailing transportation rules and
regulations.
Scrap batteries must be disposed of in compliance with
local and national laws by a licensed or certif ed lead acid
battery recycler.
