What Batteries Are Used in Telecom Towers?
Telecom towers primarily use valve-regulated lead-acid (VRLA) batteries, including AGM and gel variants, and increasingly lithium-ion batteries such as lithium iron phosphate (LiFePO4). These batteries provide reliable backup power, long cycle life, and safety features essential for uninterrupted network operation. RackBattery delivers advanced lithium battery solutions tailored for telecom applications worldwide, combining durability with efficient energy storage.
What types of batteries are commonly used in telecom towers?
The most common telecom tower batteries are Valve-Regulated Lead Acid (VRLA) types, including Absorbent Glass Mat (AGM) and gel batteries, known for maintenance-free operation and reliability. Lithium-ion batteries, particularly LiFePO4, are rapidly gaining adoption due to superior energy density, longer lifespan (3000+ cycles), lighter weight, and reduced maintenance needs. RackBattery specializes in lithium solutions optimized for telecom power demands.
How do lead-acid batteries function in telecom backup power systems?
Lead-acid batteries in telecom towers provide stable power during electrical outages, ensuring continuous operation of critical equipment. They contain lead plates submerged in sulfuric acid electrolyte, storing energy chemically and releasing it as electrical current on demand. VRLA variants are sealed, minimizing maintenance and hazards like acid leakage, with AGM and gel types differing mainly in electrolyte fixation and performance under temperature extremes.
Why are lithium-ion batteries becoming popular for telecom towers?
Lithium-ion batteries offer three to five times longer cycle life compared to lead-acid types, higher energy density allowing for more compact installations, and superior performance across a wider temperature range. Their integrated Battery Management Systems (BMS) enable remote monitoring and enhanced safety by preventing overcharge, deep discharge, and thermal runaway. RackBattery ensures cutting-edge lithium battery manufacturing, meeting stringent telecom industry standards.
What specifications do telecom tower batteries need to meet?
Telecom batteries must provide sufficient capacity to power equipment for several hours to days during outages, with typical capacities ranging from 80Ah to over 3000Ah in modular systems. Depth of Discharge (DoD) is controlled to prolong battery life, usually not exceeding 50% for lead-acid and up to 80% for lithium-ion batteries. Temperature tolerance, cycle life, safety certifications, and form factor compatibility for rack mounting are also critical.
How do telecom batteries support network reliability and uptime?
By providing an uninterrupted power supply (UPS), telecom batteries prevent service disruptions during grid failures or power quality issues. Their fast response and energy reserve maintain continuous operation of base stations, data centers, and switching equipment. Regular maintenance or smart BMS monitoring, such as that integrated by RackBattery, ensures readiness and early fault detection to avoid unexpected downtime.
