Controlling Telecom Tower Costs Using Lithium Batteries
The battery provides constant power for the electrical loads. The generator runs three to five hours every time a lead acid battery needs to be recharged.
The Solution is Lithium
Battery choice is the most critical decision to control the telecom tower’s costs. Lithium batteries feature fast charge, higher enery density and remote monitoring that make this new battery an ideal fit for reliable remote power.
Lithium Iron Phosphate (LiFePO4) batteries are the safest type within the family of lithium batteries. Lithium Iron batteries are superior in energy efficiency and cycle life compared to lead acid batteries, lowering labor costs for replacement and decreasing generator runtimes.
Each individual cell in Lithium Iron battery can be monitored remotely through an online portal. This saves the cost of onsite resistance testing which lead-acid batteries require to monitor battery health and performance.
Lithium batteries have revolutionized consumer electronics in the 21st century with their reliability and energy density, and now this proven technology is poised for further market penetration in mission-critical remote telecom sites.
Improved Efficiency and Longer Cycle life
Lithium Iron batteries offer three-times the usable life of a lead-acid battery in daily cycle applications. Longer cycle life eliminates site visits to replace failing battery banks, freeing up company time and resources.Battery charge efficiency is greatly improved with Lithium Iron, which reduces generator run time - saving fuel and maintenance costs.
Lead acid batteries waste as much as 30 percent of energy put into them due to efficiency losses, so if you provide 100 amps of power you’re only storing 70 amps in the battery.
- Lithium is able to hold more of this power, storing between 9 and 100 amps of the same charge current thanks to improved efficiency.
- Lead acid batteries suffer from slow charging in the top half of the battery – which is the part used the most during daily use. The final 20% of a charge cycle requires an “absorption” stage, which tapers charge current while holding a set voltage. This requires a longer generator run, and if charging with solar, the sun may set before the battery is able to reach full charge. Failure to complete a full charge cycle can result in premature aging and reduce the usable life of a lead acid battery.
Lithium Iron batteries do not require this wasteful absorption stage, can be fast charged, and are able to hold more of the incoming power thanks to better efficiency.
