Deka Fahrenheit® excels in outdoor plant without temperature controls.

Imagine a desert. The sand, the sun, and most of all the intense HEAT. The ultimate test for any

telecom battery. The goal was to survive an independently conducted field test in one of the harshest climates in the world, the Southwest United States, enclosed in a metal cabinet with no climate controls.

The product made to meet that challenge is the revolutionary Deka Fahrenheit.

In 2016, four strings (16 batteries) of the Deka Fahrenheit VRLA batteries were installed in cabinet cell sites located in Phoenix, AZ. The purpose of the ongoing study is a true-to-life field test with the batteries to perform until failure in a float application, just like every cellular site across the world.  Temperatures of the batteries inside the cabinets ranged from winter lows of 40°F to blistering summer highs of 125°F.  To certify product performance, a monitoring system was used to continually record string voltage, current, and temperature at each cell site.

After four years, the capacity of three strings, combining both cabinets with and without temperature compensation, averaged 99%.

There are few batteries that can survive, let alone thrive for four years in the desert with external maximum temperatures reaching over 133ºF. The Deka Fahrenheit thrived providing 99% capacity on average, with the majority of three strings starting out over 100% capacity, and by the end of the fourth year, all staying above 90% capacity.  When you need a battery that’s going to provide superior performance in either an uncontrolled or controlled OSP site, look no further than Deka Fahrenheit.
