Technical FAQs 4

What is a telecommunications outside plant cabinet?

A typical Telecommunications Outside Plant cabinet is a non-controlled environment where temperatures can reach or exceed 140 Degrees Fahrenheit. Battery Float Voltage: The float voltage is that voltage, which provides the correct amount of battery charge current to maintain an optimal state of charge in the battery cell.

Can a battery be replaced based on a defective cell resistance?

with battery suppliers that specify the warranty replacement of battery systems based on Defective DC Cell Resistance measurements. Submitting defective Cell Resistance data to the battery manufacturer will facilitate servicing of the battery warranty. The data must include at least two consecutive cell resistance readings.

What happens if the OSP cabinet temperature is too high?

Extended high temperatures will rapidly degrade the service life of the battery. The temperatures in the OSP Cabinet battery housings typically are not well regulated and can reach 120 - 140 Degrees F for extended periods of time. The OSP Cabinet typically has poor insulating characteristics and very high thermal radiation.

Can I measure DC cell resistance on OSP battery systems?

Note: Measure only the DC Cell Resistance on OSP battery systems that do not have connectors bolted or strapped between each battery block. Some systems only CLIP into a wiring harness and do not have solid connectors or straps that can be measured.
