The maximum storage times before a refresh charge is required and
recommended open circuit voltage audit intervals are:
Monoblocs and cells must be given a refresh charge when the OCV
approaches the equivalent of 2.10 Volts per cell or when the maximum
storage time is reached, whichever occurs first.
2.2. Refresh Charge
Charge the monoblocs / cells or strings at a constant voltage equivalent to 2.29 -
2.40Vpc with a minimum 0.1C
10
Amps available for a period of 24 hours.
2.3. Commissioning Charge
Before commencing operation, the battery must be given a commissioning
charge. The batteries should be charged using constant voltage with a
minimum charge current of 0.1C
10
Amps with no load connected to the
battery. Either of the following methods can be used:
•
Charge for 96 hours at the recommended float voltage of 2.29Vpc at
20°C or
•
Charge for 24 hours at the recommended boost charge voltage
of 2.40Vpc at 20°C. The battery will then be switched over to float
charging, maintaining the battery under floating voltage for 24 hours
before any discharge test.
3. Battery Location
The battery compartment/room must have adequate ventilation to limit
hydrogen accumulation. Batteries must be installed in accordance with the
EN 50272-2 standard and any other local/national laws and regulations.

Handling
SuperSafe
®
T Front Terminal and 2 volt DIN-size
batteries are supplied in a charged condition and are
capable of extremely high short circuit currents. Take
care to avoid short-circuiting terminals of opposite
polarity.
Important
Please read this manual immediately on receipt of the battery before unpacking and installing. Failure to comply with these instructions will render any
warranties null and void.
Care for your safety
2
Keep flames away
In case of accidental overcharge a flammable gas
can leak off the safety vent.
Discharge any possible static electricity from clothes
by touching an earth connected part.
Tools
Use tools with insulated handles.
Do not place or drop metal objects on the battery.
Remove rings, wristwatch and articles of clothing
with metal parts that may come into contact with
the battery terminals.
No smoking, no naked flames, no sparks
Shield eyes
Read instructions
Electrical hazard
Danger
Recycle scrap batteries.
Contains lead
Electrolyte is corrosive
Clean all acid splash in eyes or on
skin with plenty of clean water.
Then seek medical help.
Acid on clothing is to be washed
with water
Warning: Risk of fire, explosion, or
burns. Do not disassemble, heat above
60°C, or incinerate. Avoid any short
circuit. Metallic parts under voltage on
the battery, do not place tools or items
on top of the battery

1. Receiving
Upon the receipt of the shipment, check the contents for damage and
against the packing slip. Immediately inform EnerSys of any damaged
or missing items. EnerSys
®
is not responsible for shipment damage or
shortages that the receiver does not report to the carrier.
2. Storage
2.1. Storage Conditions and Time
If a battery cannot be immediately installed it should be stored in a clean,
cool and dry area. During storage monoblocs / cells lose capacity through
self-discharge. High temperatures increase the rate of self-discharge and
reduce the storage life.
The chart below shows the relationship between open-circuit voltage (OCV)
and storage time at various temperatures.
California Proposition 65 Warning
- Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to
cause cancer and reproductive harm. Wash hands after handling.
