Stand Power HR (High-Rate) Series of valve regulated lead acid (V.R.L.A.) batteries have been developed with high efficiency active materials to stimulate inside the battery with higher power output when the battery is discharged to a extent level of discharging. Along with high-density structure design for relatively smaller inner resistance which will significantly improve the performances for high rate discharging when high power output service is needed. Features 8 year design life. A recognized component of U.L. Non-spillable valve regulated lead acid battery (VRLA) design. Advanced absorbed glass mat technology (AGM) with gas recombination greater than 99%. Operates at a low internal pressure. Never needs watering, minimal maintenance. 99.7% pure lead calcium grids. Shock absorbent thick wall ABS cases. Flame retardant cases are optional Applications Alarm System Cable Television Communication Equipment Control Equipment Security System Medical Equipment UPS Power Tools Toys Emergency Power System
