Fill battery grade Sulphuric acid in all the cells up the required levels. Filiing Specific Gravity 1.245+0.005 at 27°C
Fully Charged Specific Gravity 1.245+0.005 at 270C
Charge the batteries with constant current as indicated in the table, until the top of charge voltage reaches 2.70 Volts per cell.
Global batteries Rocket SMF Calcium Batteries is the special product for automotive Industry.
These batteries give high starting current for short duration.
They are extensively used for automotive application.
However these batteries can be used for UPS application also.
Structure & Characteristics
Hydrometer
At full charge, the electrolyte specific gravity is 1.280 while at 50% of charge considered the minimum serviceable condition, the specific gravity is typically 1.220. In a typical situation when the specific gravity drops to 1.100, the battery is fully discharged.
Heat Sealed Covers
Prevent contamination and also adds to the strength and rigidity.
Include permanent flame arresters to prevent and accidental explosion from external sparks of flame.
Have hydrometer built in for faster checking.
Exclusive Patented Liquid Gas Separator
Prevents electrolyte losses by collection and returning liquid to the reservoir.
Vents allow the battery to “breathe” during temperature changes and charging
Centered Cast-on Plate Straps
Stronger than the thinner gas-burned conventional connectors.
Reduce the lever action movement resulting from road shock.
Wrought Lead-Calcium Grids
Offer considerable strength
Resistant to grid corrosion
Over-charge resistant
Minimum gasing and water usage
Less self-discharge
Resist thermal runway
Low – Resistance Envelope Separators
Encapsuate negative plates
Improve vibration durability
Prevent “treeing” and internal shorting between pos. and neg. plates
The ESG Range of SMF VRLA batteries offer outstanding performance including a 20+-year design life. Build to the higher standards and compliant with the latest IEC60896-21/22 standards. This range also offers 100% capacity out-of-box and is capable of handling deep discharges for complete piece of mind. The use of flexible connectors and the ability to be installed both horizontally and vertically allows for multiple installation possibilities.
General Features
Better discharge characteristic than normal SMF VRLA Batteries.
Non-Spillable Construction Design.
Safety valve installation for explosion proof.
Higher safety and reliable construction.
Extra Durability and deep cycle ability for heavy demand applications.
Low self – discharge characteristic.
Flexibility design for multiple installation.
