VRNM Ni-Cd battery
Performance with ultra-low
maintenance
Developed in line with long proven Ni-Cd technology, VRNM is an exceptionally
reliable ultra-low maintenance pocket plate battery incorporating special technical
features.
Delivering long life and requiring no or minimal maintenance, there is no better
solution for installations where the risk of failure is unacceptable, as in:
l
UPS systems

AMCO Saft
VRNM Ni-Cd battery
No water filling
No water filling is necessary during the VRNM service life under recommended
conditions of use because of the large electrolyte reserve, the controlled
recombination and the valve regulated venting system (topping up is possible if
required).
Valve regulated system
Controlled recombination is made possible through a specific cell design and low
pressure flame arresting vent. The risk of thermal runaway is eliminated by the
use of free electrolyte – a major advantage over VRLA batteries where starved
electrolyte is often the cause of failure.
Designed to be durable
VRNM’s tough cell containers, battery’s positive nickel hydroxide and negative
cadmium hydroxide plates, and alkaline electrolyte deliver optimum performance
without compromising structural integrity.
Quality built, quality tested
VRNM is manufactured in India; one of Saft’s many internationally accredited
ISO 9001 sites.
Calculating your battery size
It is important to specify the optimum battery size for your particular
installation. Nickel-cadmium ranges offer many capacity steps to create
the optimum battery for your application. AMCO Saft’s battery sizing
software has been developed to make your battery selection easy. Our
sales engineers have been specifically trained to fine-tune sizing of the
batteries according to your specific conditions.

Recombination Cycle:
In a flooded Ni-Cd battery following reaction occurs on over charge.
At the positive plate
40H- ➞ 2H20 + 02 + 4e–
(Oxygen evolution)
At the negative plate
4H20 + 4e- ➞ 2H2 + 40H–
AMCO Saft
VRNM Ni-Cd battery
Construction
features
(Hydrogen evolution)
During charging phase, oxygen evolution starts a little before the positive plate is
fully charged. Excess negative capacity of VRNM ensures that oxygen evolution
commences prior to hydrogen evolution.
Porous separators facilitate diffusion of oxygen that reacts with cadmium at
negative plate and chemically discharge cadmium into cadmium hydroxide.
2Cd + 2H2O ➞ 2Cd (OH)2
The current passing through the cell keeps recharging the negative electrode.
The process of oxygen generation at positive plate and its getting consumed at
negative plate is known as oxygen recombination cycle.
1. Electrode assembly
The active material is retained in pockets formed from perforated nickelplated steel strips. This mechanically robust pocket plate construction ensures
conductivity and robustness. Large surface area of negative electrode
and special additives in negative active material enhance faster oxygen
recombination hence high rate of overcharge is possible. The supporting
structure of electrodes is made of nickel-plated steel and is inert to alkaline
electrolyte. There is no corrosion and no risk of “sudden death”.
2. Separator
A thick fibrous material ensures separation between electrodes of opposite
polarity. Separator also retains the oxygen gas till it gets recombined at negative
electrodes. The separator holds generous quantity of electrolyte between plates,
eliminating the risk of thermal runaway.
6
3. Electrolyte
The electrolyte used in VRNM cells is aqueous solution of potassium hydroxide
and Lithium hydroxide. It is not necessary to change the electrolyte during the
life of the cell.

4. Terminals

Easy to bolt nickel plated terminals made of steel are provided for both polarities.

5. Cell containers
VRNM cell containers and lids are moulded from translucent polypropylene.
Containers and lids are thermo-welded to ensure airtightness.

6. Venting system
VRNM cells are fitted with low-pressure vents. This vent acts as one-way selfresealing valve to prevent air from entering cell, at the same time vents out
gases generated during over charge.

Nominal voltage: 1.2 V/cell rated (nominal) capacity
VRNM Ni-Cd battery
Rated Capacity C5 is defined as available ampere-hours (Ah) at 5 hours discharge
rate to an end cell voltage 1.0 V/cell at ambient temperature + 20°C.
Technical
Characteristics
Internal resistance
Internal resistance of VRNM at room Temperature when measured after float
charging is: 100 x 1/C5 milliohms.
Short circuit current
Maximum short circuit current in amperes is: 15 x C5 Amps. VRNM batteries can
withstand its short circuit current without damage.
Charging characteristics
VRNM batteries can be charged by the following methods:
l
Single level float charging:
VRNM batteries can be charged using constant potential charger at 1.40 to
1.43 V/cell.
80% capacity is recharged in 8 hours and 16 hours respectively at 0.2C5
and 0.1 C5 charging rates.
Full capacity is achieved in 30 hours of recharge.
l
Dual level constant potential charging:
l
First charge with a current limit of 0.1C5 to an average maximum voltage
of 1.45 V/cell
l Alternatively, if faster rate of charging is required, a voltage limit of
1.55 V/cell can be used
l After the first stage, switch to float voltage in the range 1.40 to
1.43 V/cell
l After every deep discharge, the first stage should be reapplied manually
or automatically
Special operating factors
Ripple effect
Cycling
Installation and maintenance
Like other Ni-Cd batteries VRNM can
tolerate high ripple from charging system.
Ripple up to 15% has no effect on water
loss or life of battery.
Cycling capability of VRNM is
excellent as other pocket plate Ni-Cd
batteries. Since VRNM operates at
low charging voltage, charging time
between deep cycles should be
sufficient to recharge battery.
VRNM batteries are normally supplied
filled with electrolyte and charged,
ready for immediate use. These can
be stored in this condition for up
to two years. No commissioning
charge required if commissioned
within six months from dispatch.
VRNM is a maintenance-free product
and requires minimum attention. A
visual check once in six months for
electrolyte level and cleanliness of
external components is adequate.
Over-discharge
Unlike lead-acid battery VRNM does not fail
when cells are discharged more than their
rated capacity. VRNM is designed to make
recovery from this situation.
Over charge
VRNM with its generous electrolyte
reserve is unaffected by small degree
of overcharge. In case of excessive
overcharge, a situation that will destroy a
VRLA battery, VRNM can be refurbished by
topping up.
6
Mechanical abuse
Like other pocket plate type Ni-Cd
batteries, VRNM is resistant to high
degree of shock and vibration. VRNM
cells are assembled in polypropylene,
all external metal components are
nickel-plated and are protected by
neutral grease and plastic cover.
The battery can withstand corrosive
environment.
Discharge performance
Discharge currents available for
different time durations and to
different end cell voltages are given
in tabular discharge data. Data is
based upon cell performance, after
several months of floating at 1.42 V:
this eliminates correction factors such
as “floating” which needs to be used
when sizing batteries.
