Telecom base station batteries are among the most demanding applications in the energy storage industry. Batteries must deliver reliable backup power in remote locations, extreme climates, and with minimal maintenance access for 5–10 years.
Telecom Battery Requirements
- Backup runtime: Typically 4–8 hours (varies by operator SLA)
- Cycle frequency: May cycle daily in areas with unreliable grid
- Operating temperature: -40C to +55C for outdoor cabinet installations
- Design life: 10–15 years float life for primary sites
- Maintenance: Zero or minimal maintenance required at remote sites
System Voltage
- 48V DC: Industry standard for telecom. Most telecom equipment runs on 48V.
- 2V cells: 24 cells in series for 48V systems. Standard configuration.
- Common capacities: 100Ah, 150Ah, 200Ah, 300Ah, 500Ah per string
Sizing Formula
Total Ah = (Load Watts x Backup Hours) / (System Voltage x DoD x 0.90)
Example: 3kW load, 8-hour backup, 48V, 80% DoD:
Required = (3000 x 8) / (48 x 0.80 x 0.90) = 694Ah
Use 24x CHISEN OPzV2-800 (2V 800Ah) = 48V 800Ah string
Why OPzV is the Standard for Telecom
- Longest cycle life: 1,200–1,500 cycles @ 80% DoD — survives daily cycling
- Wide temperature: -40C to +60C — handles outdoor cabinets globally
- Low self-discharge: 1–2%/month — stays charged during infrequent grid outages
- Recombinant design: No water top-up for 10+ years
- Tubular plate: Superior to flat plate in repeated deep cycling
CHISEN supplies telecom operators globally with OPzV cells from 100Ah to 3000Ah, with custom cabinet configurations available for major telecom infrastructure projects.
