It is especially designed for telecommunication application.  The outstanding advantage of VG series battery is that the width of battery is 19’’ and the two terminal battery are in the front . It is very convenient for connecting bus bar and inspect after the batteries are installed in the rack. The alloy of VG series is made through a very available way and also the positive grid is specially designed for long life. Feature in details·Long life designVanguard (VG) series of SunStone batteries are long life design batteries. Normally in the alloy of plate, the percentage of Tin is 8%. For these batteries, we double the percentage of Tin in the alloy. Also we change the percentage the percentage of Ca in this alloy.·Valve Regulated Construction (Sealed)Vanguard (VG) series of SunStone batteries are of the AGM (Absorbed Glass Mat) valve regulated (sealed) lead acid rechargeable type. The electrolyte is suspended in a specially formulated non woven glass mat separator. All the electrolyte is absorbed in this manner and provides a safe non-spillable battery.·Gas Recombination SystemThe gasses generated in the normal charge/discharge use of a rechargeable battery are internally recombined during normal operating parameters. In the fact in normal operational use, more than 99% of the gasses generated are recombined.·Safety and Automatic Valve SystemIf the pressure is over 2-5 psi the safety valve will automatically open and reseal. This promise that there is no any excessive accumulation if gas in the battery.·Heavy Duty GridsThe grids are made by heavy duty lead calcium tin alloy. This provides: Safety margin of performance condition, Excellent recovery capacity from deep discharge, Extra service life in either cycle or float application, Low self-discharge when it is not in working.·Float Service life of batteryVanguard (VG) series of SunStone batteries is designed for float life of 12 years at 20°C(68°F).·Operation in any positionBecause SunStone batteries are sealed and all the acid is absorbed in the special separators, these batteries can be operated in both vertical and horizontal position.·Wide Operation Temperature RangeSunStone batteries can be used in wide temperature range from -35°C to 45°C.·Available in flame retardant ABS material for the battery case V0SunStone batteries cases can be make by flame retardant material V0.
