Telecom towers require reliable and efficient backup power solutions to ensure uninterrupted service, especially during power outages or fluctuations. The types of batteries commonly used in telecom towers include: 1. Valve-Regulated Lead-Acid (VRLA) Batteries Absorbent Glass Mat (AGM) Batteries Description: AGM batteries use a fiberglass mat to absorb the electrolyte, making them spill-proof and maintenance-free. Advantages: High discharge rates suitable for short-term high-power applications. Maintenance-free operation. Good performance in various temperature conditions. Applications: Widely used in telecom towers due to their reliability and ease of maintenance. Gel Cell Batteries Description: Gel cell batteries use a gelled electrolyte, which makes them less prone to leakage and more resistant to deep discharges. Advantages: Better deep discharge capabilities compared to AGM batteries. Maintenance-free operation. Stable performance over a wide range of temperatures. Applications: Suitable for telecom applications requiring frequent deep discharges. 2. Flooded Lead-Acid Batteries Description: Traditional lead-acid batteries with liquid electrolyte that require regular maintenance (checking and topping up electrolyte levels). Advantages: Lower initial cost compared to VRLA batteries. Long lifespan if properly maintained. Disadvantages: Requires regular maintenance. Risk of spillage and gas emissions during charging. 3. Lithium-Ion Batteries Description: Modern battery technology offering higher energy density, longer cycle life, and lower weight compared to lead-acid batteries. Advantages: Higher energy density allows for smaller, lighter battery packs. Longer cycle life reduces the frequency of replacements. Faster charging times and better efficiency. Low maintenance requirements. Applications: Increasingly used in modern telecom installations due to their superior performance characteristics.
