East Penn Introduces Front Access High Rate Battery

East Penn Manufacturing announces the release of the Unigy HR5500ET High Rate battery with a 10-year design life for UPS service. Unique to batteries designed for high rate applications, the HR5500ET has front access terminals for easier installation and maintenance. Front access maximizes cabinet space reducing the additional clearance needed for top cable connections and extra cable lengths. Installation and maintenance is safer and simpler eliminating the need to reach over the batteries for first-time hookup or routine service. In addition, a reduction in cabinet space also allows for more power in less space.

Unigy High Rate batteries use the latest AGM (Absorbed Glass Mat) technology to lower internal resistance for superior high-rate, short-term discharges delivering critical power when needed. For extended long-term performance, the Unigy High Rate batteries feature recessed posts with epoxy post seals that act as a secure barrier to keep in acid and critical pressure. Special “puncture resistant” glass mat separators lowers internal resistance for increased high-rate power while protecting against failures and shorts. Tank-formed plates also extend life by optimizing cell voltage balance and performance. In addition, heavier, thicker positive plates are pasted from both sides for added durability and extended service life. The Unigy HR5500ET has a ten-year design life with a warranty of three-year free replacement.

Specifically designed for high-rate uninterruptible power supplies (UPS), these batteries are housed in reinforced cases constructed of polypropylene or flame-retardant plastic (rated 28 LOI), 12-volt monoblocks. Low pressure self-sealing valves prevent premature dry-out and minimize gassing. Flame arrestors are installed on all flame-retardant batteries for added safety. Utilizing state-of-the-art computer-aided design and manufacturing, Unigy High Rate batteries meet the highest quality standards in the industry.
