Batteries suit Uninterruptible Power Supplies.

Press Release Summary:

Datasafe HR series valve-regulated lead-acid (VRLA) batteries provide threaded brass post inserts and positive and negative grids of lead-calcium-tin alloy. Batteries utilize gas recombinant VRLA technology to minimize gas evolution during charging and discharging. Flame retardant ABS case material with ribbed walls and lids provide protection against shock and vibration, flame arrestors are built into each cell, and covers are bonded to containers using leak-proof heat seal.

New High Energy Density VRLA Batteries from EnerSys Offer More Power in a Smaller Footprint

Reading, PA, July 2002 - EnerSys Inc. (formerly Yuasa, Inc.) Reserve Power Group has introduced a new line of valve-regulated lead-acid (VRLA) batteries that offer superior performance while occupying less space than conventional stand-by power batteries. The new Datasafe HR series of high rate discharge batteries are ideal for Uninterruptible Power Supply (UPS) and other applications that require maximized space utilization combined with high energy density.

Threaded brass post inserts provide maximum conductivity and ease of installation; positive and negative grids are constructed of lead-calcium-tin alloy for long life and efficient recharge. The batteries use proven gas recombinant VRLA technology that minimizes gas evolution during charging and discharging, allowing battery installation in cabinets or on stands in a variety of environments such as a computer room to maximize space utilization. The gas recombinant technology also eliminates the need for watering, reducing maintenance costs.

The Datasafe HR batteries are designed with safety in mind: flame retardant ABS case material with ribbed thick walls and lids provide protection against shock and vibration, flame arrestors are built in to each cell, and covers are bonded to containers using a leak-proof heat seal. Absorbed Glass Mat (AGM) separators completely absorb the electrolyte, so there is no free acid to leak if the battery case is accidentally damaged. The batteries also meet critical industry standards including UL approval, IATA certification for air transport, and US DOT classification for non-spillable batteries.

Constant power discharge ratings at room temperature for the Datasafe HR205, HR300, HR330, HR400 and HR500 are 204, 284, 330, 381 and 506 watts/cell at the 15-minute rate (1.67 end voltage/unit). Each battery features a 12-volt mono-block design with an operating temperature range of 32°F to 104°F (0°C to 40°C). Optional lifting handles are also available. Dimensions for the compact Datasafe HR series are 8.6"L x 6.5"W x 8.7"H (HR205), 10.3"L x 6.9"W x 8.2"H (12H300), 12.3"L x 6.5"W x 8.7" (HR330), 13.6"L x 6.8"W x 8.4"H (12H400), and 13.6"L x 6.8"W x 10.8"H (12H500).

The Datasafe HR batteries are one of the Hawker product lines acquired by EnerSys as part of the purchase of the Energy Storage Products Group of Invensys plc. in March of 2002.

Pricing for an HR205 Datasafe battery starts at $180 each. Delivery is 4 weeks ARO.
