The NSB 210FT NorthStar Red Telecom Battery is a high-performance valve-regulated lead-acid (VRLA) battery designed for critical telecommunications infrastructure. While specific technical details for the 210FT variant aren’t publicly disclosed, NorthStar’s NSB series typically features sealed maintenance-free designs with 2V/12V configurations, optimized for UPS systems, DC power backup, and industrial applications requiring long-duration discharge cycles (e.g., 8–20 hours at C10 rates). These batteries prioritize vibration resistance and deep-cycle capabilities, with AGM technology ensuring spill-proof operation.

What distinguishes NSB series telecom batteries?
NorthStar NSB telecom batteries utilize AGM VRLA technology for zero maintenance and superior deep-cycle performance. Engineered for 15+ year lifespans in 20–25°C environments, they deliver 2V or 12V outputs with capacities spanning 70–3,650Ah. Their robust construction withstands harsh vibrations common in telecom towers and mobile base stations.
Unlike standard lead-acid batteries, NSB models incorporate high-purity lead plates and compressed glass mat separators, reducing internal resistance by 30% compared to flooded alternatives. For example, the NSB2-2600 variant maintains 2.1V/cell under 260A load for 10 hours. Pro Tip: Pair with compatible float chargers (2.25–2.3V/cell) to prevent sulfation during standby.
| Feature | NSB Telecom | Standard VRLA |
|---|---|---|
| Cycle Life @50% DoD | 1,200 cycles | 500 cycles |
| Vibration Resistance | MIL-STD-810G | Commercial Grade |
| Self-Discharge/Month | ≤3% | 5–8% |
How do NSB batteries perform in backup systems?
NSB telecom batteries excel in long-term backup scenarios, offering 96–120 hour runtime at C100 rates. Their low self-discharge (3% monthly) preserves charge during extended grid outages. Advanced AGM separators enable 2x faster recharge than gel batteries—critical for solar-powered telecom sites requiring daily cycling.
Practically speaking, a 2V 3,650Ah NSB2-3650 unit can power a 500W telecom load for 14.6 hours (500W ÷ 2V = 250A → 3,650Ah ÷ 250A = 14.6h). However, remember Peukert’s Law: Actual capacity drops 15–20% at high discharge rates. Pro Tip: Derate nominal capacity by 25% when designing backup systems for telecom switches.

FAQs
Yes, with IP55-rated enclosures. However, ambient temperatures must stay within -20°C to +40°C—solar shading and ventilation are mandatory in hot climates.
What’s the warranty for NSB telecom batteries?
NorthStar typically offers 5–7 year pro-rata warranties, contingent on proper float voltage (2.25–2.3V/cell) and ≤25°C operating temperatures.
