Reliable backup power is critical for telecom base stations, data transmission centers, and communication networks. Battery failure can cause serious service interruptions and economic losses. Among stationary battery technologies, OPzV and OPzS tubular lead-acid batteries are widely used in telecom backup systems due to their long float life and high reliability.
This article explains how to select the correct battery type for telecom applications.
1. Special Requirements of Telecom Backup Batteries
Telecom backup batteries must provide:
- Long float service life (15–25 years)
- Stable voltage under constant float charge
- Low self-discharge rate
- High safety and low gas emission
- Minimal maintenance
Telecom sites are often unmanned and installed indoors, making maintenance-free operation a critical factor.
2. OPzV Batteries: Preferred Choice for Modern Telecom Systems
OPzV gel batteries are widely recognized as the best solution for telecom backup power.
Main advantages include:
- Maintenance-free design
- Very low gas emission
- Excellent float charge stability
- Long design life up to 20–25 years
Most telecom operators prefer OPzV batteries for indoor base stations, urban telecom rooms, and containerized communication shelters.
3. When OPzS Batteries Are Still Used in Telecom Projects
OPzS flooded batteries are still applied in:
- Large central switching stations
- Outdoor telecom power rooms
- Projects with permanent maintenance personnel
However, strict ventilation systems and regular inspection schedules are required to ensure safety and performance.
4. Safety and Installation Considerations
Telecom environments often have limited space and strict safety regulations.
OPzV batteries provide:
- Spill-proof structure
- Flexible installation positions
- Reduced risk of acid leakage
OPzS batteries require:
- Acid-resistant battery rooms
- Hydrogen gas exhaust systems
- Regular electrolyte checks
5. Lifetime Cost Comparison
Although OPzS batteries may appear more economical at the beginning, the maintenance cost and safety management often make OPzV batteries more competitive in long-term telecom projects.
Conclusion
For modern telecom backup systems, OPzV tubular gel batteries are generally the optimal choice due to their maintenance-free operation, high safety, and long float life.
