Design & Construction

Positive Plate	:	Flat pasted type with Lead Alloy to impart deep discharge capability, long life and low self discharge properties to the grid.
Negative Plate	:	Flat pasted type with Lead Calcium Alloy to impart Maintenance Free properties to the grid.
Separator	:	Highly porous and Absorbent Micro porous Fibre Glass Mat (AGM) Separator
Container & Lid	:	Container & Lid-ABS material (imported) -Light Weight, Sturdy Weather proof, long lasting and heat sealed.
Safety Valve	:	Self-resealing, explosion-proof, pressure regulated safety valve With porous Acid filter.
Terminals	:	Lead terminals with conductive brass inserts ensuring high discharge characteristics.

Salient Features

	Design float life of 20 years on float with recommended charging method.
	Design cycle life @ 27° C 4000 cycles at 20 % Depth of Discharge 2000 cycles at 50% Depth of Discharge 1200 cycles at 80% Depth of Discharge
	Very low internal resistance; superior high current discharge performance.
	Safety valve automatically regulates the internal pressure of the cell and “special double layer” sealing structure at terminals fully solves the acid leakage problem from terminals.
	The porous “acid filter” in the vent plug retains acid within the cell and “flame arrestor” in the vent plug avoids risk of explosion.
	Full capacity can be reached for the first time itself @C/10 discharge performance of battery.
NOTE:	All values are rated at 27 degree Celsius.
