2V Battery — Frequently Asked Questions

What 2V battery types does Naradex manufacture?
Naradex manufactures three types of 2V batteries: NL2 series AGM (absorbed glass mat) stationary batteries from 150Ah to 3,000Ah for data center and telecom backup; OPzV2 series tubular gel batteries from 100Ah to 3,000Ah for deep cycle solar and telecom applications; and OPzS series flooded tubular batteries from 200Ah to 800Ah for utility installations with maintenance access.
What is the capacity range for Naradex 2V batteries?
Our 2V battery range spans from 100Ah to 3,000Ah across all chemistries. NL2 AGM: 150-3,000Ah. OPzV tubular gel: 100-3,000Ah. OPzS flooded: 200-800Ah. Common telecom capacities include 200Ah, 500Ah, 800Ah, 1000Ah, 1500Ah, and 2000Ah cells configured in 24-cell strings for 48V DC systems.
How long do 2V stationary batteries last?
Design life varies by chemistry: NL2 AGM delivers 15+ years in float applications at 25 degrees C. OPzV tubular gel delivers 20+ years with 2,000+ cycles at 80% DOD. OPzS flooded delivers 20+ years with 2,000+ cycles at 80% DOD but requires periodic water refilling. Real-world installations typically achieve 12-18 years depending on temperature and cycling conditions.
What are 2V batteries used for?
Large-format 2V cells are used in mission-critical stationary power systems including telecom BTS backup (48V strings), data center UPS, power utility substations, solar energy storage, railway signaling, and nuclear power plant emergency systems. The 2V single-cell format allows flexible string assembly (24 cells for 48V, 54 cells for 110V, 108 cells for 220V) and individual cell replacement without replacing the entire bank.
What is the MOQ for 2V battery orders?
For standard Naradex-branded 2V batteries, we accept small quantity orders for evaluation — even a single 48V string (24 cells). For OEM orders with custom branding, the minimum order is one 20ft container. We offer sample programs for first-time buyers to validate performance before committing to bulk volumes.
How do I choose between AGM, gel, and flooded 2V batteries?
Choose NL2 AGM for indoor, temperature-controlled environments where cost efficiency matters (data centers, indoor telecom). Choose OPzV gel for unmanned sites, outdoor installations, deep cycling, or extreme temperatures — highest total reliability. Choose OPzS flooded for utility-scale installations with dedicated maintenance staff — lowest per-Ah cost with 20-year life.
