How to select the right battery backup for telecom sector?

  Power outages are one of telecom companies’ worst nightmares, as they lead to loss of revenue, customers, image, and so on. In response, internet and telephone providers have expressed a keen interest in having a power backup system. There is a wide choice for telecom companies regarding which backup system they want such as diesel and natural gas generators, fuel cells and batteries.

Types of batteries used for telecommunication:

Batteries convert chemical energy directly into electrical energy. Telecom power systems are responsible for every-day internet, high-speed data, telephone, and other communication services. As global demand for these services continues to increase, the need for reliable wireless telecom battery backup equipment rises. The batteries used in telecom sector are mainly two types:

• Lead acid battery
• Li-ion battery

The majority of batteries used in the telecom industry are a Lead-Acid type. The lead-acid battery segment contributed the majority of shares toward the battery market in telecommunication industry. Lead-Acid batteries are an inexpensive design compared to newer technologies such as Lithium-Ion; however, Lead-Acid batteries have a lower energy density, meaning that larger and heavier batteries are required to produce the same power equivalence of a smaller, Lithium-Ion battery.

Valve-regulated (commonly referred to as sealed) lead-acid batteries are normally used as the backup power source for telecom power systems, due to their low operating costs. The battery string is comprised of 24 series-connected battery cells to make 48V. The battery plants are normally designed to support the telecom load to a final battery voltage of 1.75~1.8V/cell.

In the other hand, Li-ion batteries have definite technical advantages in terms of power to weight to volume ratio, absence of pollutants like acid and lead. Lithium-ion or Li-ion batteries have more than double life than of traditional lead-acid batteries and thus help to cut cost. Lithium-ion (Li-ion) — Telecom systems need small power sources to back-up the supply to mobile-phone relay stations, cable TV terminals and other facilities. Because these power systems need to be small and lightweight, they need to use batteries with an energy density higher than that of VRLA batteries.

Important criteria while choosing battery backup:

Among several kinds of lead acid batteries, some models are usually designed or chosen specially for Telecom market to ensure maximum performance according to the load capacity. Here is some important criteria while choosing battery:

• Special design comply with telecom 19''/ 23'' cabinet for space limitation;
• Deep cycle ability and high cycle life;
• Wide operating temperature range as well as high  temperature sustainability;
• Maintenance free battery for trouble free operation in remote site;
• Negligible gassing ;
• Spill proof and leak proof ;

• Scalable;
• Operation in any suitable position;
• Compatible with off-grid energy storage system.

In compatible with the above criteria EverExceed offers an extensive portfolio of Modular Range VRLA battery, Modular Max range VRLA, Front access FT range VRLA, Front access FT Gel range VRLA, Unilyte range VRLA, High rate range VRLA, Standard range VRLA, Tubular OPzV range VRLA, Flooded Tubular OPzS and Lithium Iron batteries as well as rectifier system to serve the telecommunications industry.
