MICROLYTE + Plus Valve regulated batteries are of the absorbed electrolyte type. The cells are designed so that a
controlled amount of electrolyte is contained within an absorbent non woven separator material that separates the
battery plates. This type of separator construction allows full wetting of the plates with the available electrolyte and
also allows the passage of oxygen generated during charging. This construction is generally referred to as absorbed
glass mat (AGM) type
MICROLYTE + Plus Valve regulated batteries are sealed with the exception of a one way valve that opens when
excess pressure builds up inside the battery, the valve automatically reseals itself. The recombination of gases is
accomplished by allowing oxygen produced at the positive plate during charging to pass through the separator material
to the negative plate where the recombination reaction occurs The valve controls the internal pressure of the battery to
optimize the efficiency of the recombination reaction and minimize the quantity of electrolyte released as gas.
Introduction
SEC Industrial Battery Co. is a large producer of modern technology, valve regulated (sealed) batteries. In its new
battery manufacturing facility it has been able to draw on a wealth of international experience and knowledge to
produce a high quality, reliable lead acid battery. The continuing installation of the most modern production equipment
makes continuous product improvement possible.
General Features
*
Valve Regulated Construction (sealed)
The SEC valve regulated AGM rechargeable lead acid battery allows safe, trouble free operation in any
position. There is never any requirement to top up electrolyte because over 99% of all Gases generated in
normal operation are recombined inside the battery.
*
Immobilized Electrolyte
Due to the type of construction, the batteries can be shipped by sea, road or air without special handling and
packaging precautions. Terminals are protected from the possibility of short circuit at all times.
*
Low Self Discharge
Because of the use of Lead Calcium grids batteries can be stored for long periods of time without recharge.
*
Cycle or Stand-By Service
Batteries are suitable for either cycling or standby Float service.
*
Tough Construction
SEC MICROLYTE + Plus batteries utilize tough, high impact resistant and non-conductive ABS plastic for
cases and lids. Batteries are also available in Flame Retardant ABS cover and case as an option.
*
Compact Design
SEC MICROLYTE + Plus batteries utilize virgin lead and the best possible raw materials to build a high
energy density battery. The International design team has a policy of continuous product improvement.

NUMBER OF CYCLES - IEC 896 part 2
Battery Life
Battery Life depends on a number of key factors. These include:
*
Operating temperature of the battery
*
Method of charging
*
Actual use of the product i.e. Float Service or cycle life
*
Correct sizing etc.
Float Service
The float service is effected by the factors listed above and the number of and depth of discharge the battery
suffers during its life time. Basically the more discharges suffered and the deeper the discharges, the shorter
battery life.
Cycle Life
Giving due consideration to the above key factors, the actual life of a battery in cycle service is dependent on
the depth of discharge of each cycle. The greater the depth of discharge of each cycle the lesser the number
of cycles available from the battery.
Battery Storage
SEC MICROLYTE + Plus batteries have excellent charge retention characteristics, meaning that the
self-discharge rate is low, less than 2% per month at 20 Deg C. To ensure the battery does not over
discharge during storage, or when not in use, it is necessary to understand what is meant by fully
discharged. A discharged battery can be determined by the open circuit voltage of the battery.
Typically a battery is fully discharged when the open circuit voltage reaches 1.92 Vpc (11.5V) in a
12V battery.

In discharging a battery, lead sulphate (sulphation) is formed. If the battery is recharged as soon as
discharge is completed then the lead sulphate is converted back into active material and electrolyte.
However, on self discharge the lead sulphate that is formed may become non recoverable. That is,
it cannot be recharged. The lower the voltage that a battery is allowed to fall to under self discharge,
the more likely it is that the sulphate formation will not be reversible and the battery will be damaged
beyond recovery.
Precautions against over Self Discharge
*
The batteries should be stored in a cool, dry place 25C or below
*
The batteries should not be stored in direct sunlight.
*
The batteries should not be subjected to an external heat source.
*
An adequate stock control system should be introduced - first in first out basis.

Supplementary charge required.
This supplementary charge will help to
recover the capacity and should be made as
early as possible.
Supplementary charge may often fail to
recover the full capacity.
The battery should never be left at less then
60%

Storage period (month)
Supplementary Charge
It may be necessary to give the batteries a refreshing charge during the period the batteries are being
stored. Maximum recommended storage times are detailed below, if storage exceeds these times or
the open circuit voltage of a battery being stored falls below 12.40 Vpc (6.2 Vpc) then it is recommended
