Sealed Valve Regulated Construction Battery Life in Cycle Life
* These batteries are of the Absorbed Glass Mat (AG M) or
CELLYTE 12FTG batteries are suitable for deep gelled gelled electrolyte technology (Gel). The electrolyt e in the cell is
immobilized in a specially form ulated non woven glass mat
separator or in a thixatropic Gel. All the acid is abs orbed in this
manner providing a safe non-spillable battery. |
Battery Life in Cycle Life
* CELLYTE 12FTG batteries are suitable for deep
cycle service battery life will depend on temperature,
depth and frequency of cycling, however the use of
the optional Catvent Catalyst will improve life in
temperatures up to 30 C. |
Gas Recombination System
* The gasses generated in the normal charge / disc harge use ofa rechargeable lead acid battery are internally recombinedduring normal operating parameters and in normal operationaluse, more than 99% of the gas generated is recombined. |
Battery One-Way Safety Valve
* When pressure builds up in the cell the B & S
German safety one-way valve opens at 2-3 psi and
releases the excessive pressure and then closes.
The one-way valve does not allow the ingress
of oxygen which is harmful and reduces battery life. |
SEC Catvent - Catalyst Vent (Optional)
* SEC's VRLA cells incorporate the Phi ladelphia Scientific Monoblocprecious metal Catalyst Catvent which prevents the negativeplate from depolarizing reduces the cell float current by upto 50%, reduces the cell gassing by about 80% , reduces celldry out which is the major cause of VRLA battery failure |
Temperature Range for Normal Operation
* CELLYTE 12FTG batteries have a wide operating temperaturerange -25 C. to +55 C. However for maximum life it isrecommended to operate the battery at 20 C. to 30 C. |
Battery Maintenance
* The battery has been designed and built such that no addition
of electrolyte or water is needed during the life of the batt ery.
|
Plate Design and Paste Formulation
* SEC has optimised the plate and paste f ormulation to maximise
the operating life of the battery. The High Tin (1.6%) / Calcium
plate alloy is used to extend battery life and cycling c apability.
Past formulation will provide excellent recovery from deep
discharge. With low self dis charge to ensure maximum storage
time when not in use
|
Battery Life in Float Service
* CELLYTE 12FTA&G batteries are suitable f or float / standby
service with a design life of 12 years at 20C. |

Benefits of Catalyst in SEC VRLA Batteries
Catalyst Reduces Float Current
One of the most immediate, observable effects of installing
a catalyst in a VRLA cell is a sudden drop in the float current.
Typically float currents are one half or less when a catalyst is
installed. Adding a catalyst to the cell prevents some of the
oxygen reaching the negative plate and allows the negative
plate to stay polarised. This means that less current needs to
be supplied to the cell from the charging system, manifesting
itself as lower float current, leading to the following benefit :-
* Minimize water loss
Gasses are recombined into water inside the cell rather
than exiting the cell. Too much gas leaving the cell can
lead to premature dry-out and cell failure. Cell dry out has
been predominant cause of customer dissatisfaction with
VRLA technology.
* Increased life
There are many potential failure modes of VRLA cells.
A number of these failure modes can be mitigated by the
catalyst technology such as: Cell dry out, positive plate
corrosion, thermal runaway, capacity loss due to negative
plate depolarization.
* Minimize positive plate corrosion
A reduction in float current reduces the amount of over- charge
on the positive plate which directly impacts thecorrosion rate.
The design life of a lead acid cell is basedon the corrosion
of the plate barring any other unforeseenfailure modes.
* Maintain cell capacity
Many VRLA cells in service are failing capacity tests
because their negative plates are depolarized In fact
significant capacity increases have been seen on some
cells just by installing a catalyst.
