Handling
PowerSafe
®
V-FT 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.
English
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
Re-cycle 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
60ºC, or incinerate. Avoid any short
circuit. Metallic parts under voltage on
the battery, do not place tools or items
on top of the battery

The maximum storage times before a refresh charge is required and
recommended open circuit voltage audit intervals are:
Monoblocs must be given a refresh charge when bloc voltages approach
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 or strings at a constant voltage equivalent to 2.29 -
2.40Vpc with 10% of the C
10
current 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
with no load connected to the battery.
Either of the following methods can be used:
•
Charge for 7 continuous days 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 to a maximum of 1% by volume of free air.
1. Receiving
1.1. In-Transit Damage or Short Shipments
Upon receipt of the shipment, please check that the items delivered are
undamaged and match the carrier’s Bill of Lading. Report any damage or
shortages to the carrier. EnerSys
®
is not responsible for shipment damage
or shortages that the receiver does not report to the carrier.
1.2. Shipment Damage or Shortages
Open the shipping containers and check the contents for damage and
against the packing slip. Immediately inform EnerSys of any damaged or
missing items. EnerSys is not responsible for damaged or missing items
after a shipment has been in storage.
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 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.
