VRLA BATTERIES FOR STANDBY POWER APPLICATIONS

Valve-Regulated Lead Acid -- VRLA batteries are designed for the long standby back-up power requirements of wireless/PCS telecommunications, MTSO’s, central offices, utilities, switchgear and control applications. Panasonic Battery has 400,000 square feet of state-of-the-art manufacturing facilities in North America dedicated to producing VRLA batteries for a variety of applications.

Valve regulated construction means the batteries never have to be topped off with water during their service life.

MSE Applications:

MSE Features & Benefits:

	Advanced micro porous absorbed glass matt separator - Minimizes diffusion of oxygen into the separator, reducing battery float charge current which suppresses the corrosion rate of the positive grid and extends the life of the battery.
	Positive grid is a lead-calcium-tin alloy; lead-calcium negative plate material has increased density - Tin improves resistance of the positive electrode (plate) to corrosion and produces slower plate growth; a denser negative plate lowers float charge current needed by the battery and thus reduces heat generation in the cell increasing battery life.
	Resistance to Thermal Run-Away - By suppressing the float charge current, not only is the life span of the battery increased, the generation of heat by the battery is substantially reduced. The result of this reduction is increased resistance to thermal run-away.
	Epoxy post terminal seals - Resists electrolyte creepage through terminal posts. Lead alloy terminal resists oxidation. Brass insert maintains bolt torque.
	Polypropylene cover and jar (MSE 500 - 1430) - Flame retardant components (UL94VO/LOI 28%), minimizes water loss and the high-impact resistant polypropylene reduces impact damage.
	Heat Seal Process for cover-to-jar seal - Cover is heat sealed to jar and tested for seal leaks. Factory automated helium leak down test process, 100% jar-to-cover seal leak test.
	Color-coded epoxy post seals - Allows for ease of identification of positive vs. negative terminal.
	Float Voltage - 2.23-2.25 volts per cell @ 25ºC (77ºF) optimizes cell efficiency.
	Safety vent, low-pressure release @ 2 psi, self-resealing - Releases gas when battery is over-charged
	Built-in flame arrestor - Prevents flame or sparks from entering the cell

MSE Modular Battery Rack Construction:

	Thermal Management - Battery rack design has cooling channels to provide cell ventilation to increase life by reducing heat build up around cells.
	Front Access Design - Provides fast easy access to all cells.
	Easy Installation - Modules can be stacked and connected on site.
	Vertical Configuration - Can increase floor space by stacking up to eight modules high.
	Seismic Design - Certified to Zone 4 earthquake requirements.
	Safety - Cell terminal posts and inter-cell connectors are protected to prevent accidental shorts by a clear, flame retardant plastic safety shield. Each shield has access ports for individual cell voltage readings.
	Module Protective Coating - Modules have durable powder coat finish.

Flexible User-Friendly Design:

	Customized Installation - Top or side-mounted terminal plate assemblies with protective covers.
	Optional Equipment Mounting Plate - Designed to allow DC rectifier power plant to mount on top of battery.
	100% capacity at shipment
	Easily recyclable - Contains no cadmium.
