Manufacturer48V Systems, 15-20 Year Life
Naradex manufactures telecom backup batteries with -40°C to +55°C operating range,48V string configuration, and15-20 year design life. Built for BTS sites, cell towers, and communication infrastructure worldwide.
- 2V AGM (NL series): 150Ah to 3,000Ah — indoor BTS rooms
- 2V OPzV (tubular gel): 100Ah to 3,000Ah — outdoor cabinets
- OEM / Private Label — your brand, our factory
Telecom Battery Solutions: AGM vs OPzV
Choose the right battery chemistry for your telecom infrastructure. Indoor BTS rooms benefit from AGM cost efficiency, while outdoor cabinets demand OPzV gel durability.
NL2 AGM — Indoor BTS
2V AGM stationary batteries, 150-3,000Ah. 15+ year float life, 800+ cycles at 50% DOD. Cost-effective choice for temperature-controlled telecom shelters and equipment rooms.
OPzV Gel — Outdoor Cabinets
2V tubular gel batteries, 100-3,000Ah. 20+ year design life, 2,000+ cycles at 80% DOD. Zero maintenance for remote BTS sites and outdoor cabinets in harsh climates.
48V String Configuration
24 cells in series for standard 48V telecom DC systems. Battery strings from 100Ah (4.8kWh) to 3,000Ah (144kWh) to match any backup time requirement from 2 to 72+ hours.
-40°C to +55°C Range
OPzV gel electrolyte maintains ionic conductivity in extreme cold and heat. Reliable backup from Arctic base stations to desert cell towers without external temperature management.
Zero Maintenance
Sealed valve-regulated design eliminates water refilling. No acid fumes, no corrosion risk. Install once and forget — critical for unmanned remote telecom sites.
Fast Recharge
High charge acceptance for rapid recovery after grid outages. Optimized plate design enables full recharge within 8-12 hours to prepare for the next power failure event.
AGM vs OPzV for Telecom: Which to Choose?
Both technologies serve telecom backup. Your choice depends on installation environment, budget, and maintenance access.

|---|---|---|
| Design Float Life | 15+ years | 20+ years |
| Cycle Life (80% DOD) | 300-500 cycles | 2,000+ cycles |
| Cycle Life (50% DOD) | 800+ cycles | 3,300+ cycles |
| Temperature Range | -25 to +60°C | -40 to +55°C |
| Maintenance | Zero | Zero |
| Acid Stratification | Possible in tall cells | None (gel electrolyte) |
| Self-Discharge | ≤3% / month | ≤2% / month |
| Capacity Range | 150-3,000Ah | 100-3,000Ah |
| Best For | Indoor BTS rooms, data centers | Outdoor cabinets, remote sites |
| Relative Cost | Lower initial cost | Higher — lower TCO over 20 years |
