Introduction

The Power Standby Series of valve regulated lead acid 
(V.R.L.A.) batteries have been developed and refined 
by Power Battery since 1972. It has been the battery of
choice by many of the original equipment manufacturers 
throughout the world. Our state of the art V.R.L.A. 
design utilizes an absorbed glass mat (A.G.M.) separator
technology to immobilize the battery electrolyte. There is 
never any need to add water to the cells and in fact all 
vents are factory sealed. 
These batteries are the ideal choice for U.P.S., Emergency 
Lighting,Switchgear and other standby applications which 
need reliable, high rate power. Since these batteries are 
low-gassing they require no special ventilation. Additionally, 
a compact design makes them perfect for low maintenance 
and space restricted applications.

	Ten 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 polypropylene cases.
	Flame retardant cases are optional (TC and SLF models).
	TC and SLF models meet U.L. 94.V0 requirements, and have oxygen index greater than 28%.
	Cold forged non-porous terminal bushings eliminate post leakage.
	Thermally welded cover to case bond, eliminates both acid and electrical leaks.
	Over-sized, through the partition inter-cell welds provide low resistance connections with minimal power loss.
	Each cell has a low pressure safety release venting system recognized per U.L. 924.
	Measured high vacuum acid fill reduces electrical variability between cells.
	100% recyclable materials, MSDS.

	Surface transport. Classified as non-hazardous material as relates to DOT-CFR Title 49 part 171-189.
	Water transport. Classified as non-hazardousmaterial as per IMDG amendment 27.
	Air transport. Complies with IATA / ICAO, special provision A67.

Electrical specifications

Operating
temperature range

Discharge: -40ºF (-40ºC) to +140ºF (60ºC)
Charge:      -4ºF (-20ºC) to +122ºF (50ºC)

Ideal operating 
temperature range

+68ºF (20ºC) to +77ºF (25ºC)

Charging voltage

Float operation:     2.25 to 2.30 V.P.C.
Cycling operation: 2.35 V.P.C.

Charge voltage temperature
compensation factor

Temperature correction factor for float
voltage charge is to add 1.7mV/ºF (3mV/ºC)
below 77ºF (25ºC) and subtract 1.7mV/ºF
(3mV/ºC) above 77ºF (25ºC). This correction
factor only applies to temperatures between
32ºF (0ºC) and 104ºF (40ºC)

Maximum charging currents

Partially discharged - self limiting
80% to 100% discharge - C/4 amperes

Storage time from a fully charged condition

6 months at 77ºF (25ºC)
(less at higher temperatures)
