INTRODUCTION : RELIABILITY is the worldwide supplier of Lead Acid batteries. SP Series Batteries are the most common first generation delicate products which is designed with AGM (Absorbent Glass Mat) technology and high performance electrolyte. SP Batteries are made up of 2V cells to produce 6 and 12V batteries. Each cell, in a charged state, is made up of electrodes of Lead (Pb) and Lead Dioxide (PbO2) in and electrolyte of Sulphuric Acid (H2SO4). In a discharged state, both electrodes turn into Lead Sulfate. This process is completely reversible when the battery is recharged. That’s why they are designated low maintenance lead acid batteries or recombination batteries. 2.

SALIENT FEATURES: • LOW MAINTENANCE: The RELIABILITY SP batteries do not need to check or add water or any other specific gravity during the whole service life of the battery. • LOW SELF DISCHARGE The RELIABILITY SP batteries. has a very low self discharge which means it can maintain its stored power for months. This very low self discharge characteristic is what makes RELIABILITY SP Batteries very popular amongst most battery users. • SAFETY & RELIABILITY: The SP batteries specially designed Valve Regulation System enables opening of safety valves if the internal pressure exceeds 2psi which automatically reseal on pressure reduction. • NO MEMORY EFFECT: The RELIABILITY SP batteries have no memory effect during whole service life. • FLAME RETARDANT DESIGN: The RELIABILITY SP batteries casing is made of ABS material which makes them safe and Flame Retardant. • NO LEAK CONSTRUCTION: Due to sealed construction and suspension of acid inside battery in a formulated nonwoven glass mat separator there are no leaks during normal battery operation. • ELECTROLYTE SUSPENSION: The RELIABILITY batteries utilise an electrolyte suspension system consisting of a high porosity, glass fiber material which in conjunction with the plate, totally absorb and contain the electrolyte. • GAS RECOMBINATION: During the charge/discharge cycle the gasses are generated and recombined as normal operation. More than 99% of the gases generated are recombined efficiently. • HEAVY DUTY GRIDS: The grids are made from heavy duty Lead Calcium Tin Alloy. This provides: Safety margin of performance condition, Excellent recovery capacity from deep discharge and Extra service life in either cyclic or float application. • CYCLIC OPERATION SERVICE LIFE: The SP series are designed for more than 1200 charge/discharge cycles. The actual times will depend on the Depth of Discharge(D.O.D). • FLOAT SERVICE LIFE: The SP series are designed for a Float Service Life of 5 years at 20°C(68°F). • OPERATION IN ANY POSITION RELIABILITY Batteries are sealed and all the acid is absorbed in the special separators, the batteries can be operated in both vertical and horizontal positions. DATASHEET Ver 3.1 Feb-2011 SP RANGE VR-SLA BATTERIES 5. SP BATTERY CONSTRUCTION: Positive & Negative Electrode Terminal Positive and negative electrode terminals may be Faston Tab Type, Bolt fastened Type, Copper Insert Type or Spring Type, depending on the type of the battery and requirement of customers. Sealing of the terminal is achieved by a structure which secures long adhesive-embedded paths and by the adoption of strong epoxy adhesives. Battery Plates: The Positive Plates are plate electrodes of which a grid frame of Lead-Tin-Calcium Alloy holds porous Lead Dioxide as the active material. The Negative Plates are plate electrodes of which a grid frame of Lead –Tin-Calcium Alloy holds Lead as the active material. Separators Separators, which retain electrolyte and prevent shorting between positive and negative plates, adopt a non-woven fabric of fine glass fibers which is chemically stable in the acidic electrolyte. Being highly porous, the separators retain electrolyte for the reaction of active materials in the plates. Electrolyte Acid is used as the medium for conducting ions in the electro-chemical reaction within the battery. Battery Case Material: Unless otherwise specified, the battery case and cover are made of ABS (Acrylonitrile Butadiene Styrene - chemical formula (C8H8)x· (C4H6)y·(C3H3N)z) which is a common thermoplastic. ABS is amorphous and therefore has no true melting point Its glass transition temperature is approximately 105°C (221°F). DATASHEET Ver 3.1 Feb-2011 SP RANGE VR-SLA BATTERIES 6. SP BATTERY LIFE: SP Battery life depends on a number of key factors. These include: • Quality of Charger (Ripples) Actual use of the products i.e. Float or Cyclic Life • Battery Operating temperature • Charging Method • Correct Sizing Float Service The float service is affected by the factors listed above and of the number of and depth of discharge the battery suffers during its life time. Basically the more discharge and the deeper the discharges, the shorter the battery life. Cyclic Life: Giving 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 Residual Capacity/ Life: The RELIABILITY SP Series Batteries have excellent charge retention characteristics, meaning that the self-discharge rate is low, less than 2% per month at 20ºC(68ºF). The state of discharge of a battery can be determined by the open circuit voltage to ensure the battery does not over discharge while in storage, or when not in use. It is necessary to understand what is meant by a full discharge. Typically a battery is fully discharged when the open circuit voltage reaches 1.92VPC. The higher the discharge current the quicker the battery reaches a fully discharged state, and the lower current the longer it takes. When the battery has discharged the battery must be recharged immediately to 100% capacity. Residual Capacity Test Results DATASHEET Ver 3.1 Feb-2011 SP RANGE VR-SLA BATTERIES END OF DISCHARGE VOLTAGE: When a battery is discharged, lead sulphate (Sulphation) is formed. If the battery is recharged as soon as discharging is complete then the lead sulphate is converted to active material and acid. However, on self-discharge the lead sulphate that is formed may not become reversible again. The lower the voltage that a battery is allowed to fall to under self-discharge the more likely it is that the sulphate formation is not reversible and the battery will be damaged beyond recovery. Please pay attention to the following conditions of storage battery over self-discharge: • The batteries should be stored in a cool, dry place 25ºC 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.
