Telecom Base Stations

Cellular networks demand 99.999% uptime. As a specialized telecom battery manufacturer since 2006, Naradex supplies AGM VRLA batteries to operators across 100+ countries — keeping BTS equipment running when grid power fails.

The Challenge

  • Grid power outages cause immediate service disruption and revenue loss
  • Remote tower sites require batteries that work reliably without maintenance
  • Extreme temperatures at outdoor installations degrade standard batteries
  • Frequent cycling from unstable power grids shortens battery lifespan

The Naradex Solution

Naradex ND12 and NL2 series batteries are engineered specifically for telecom backup power. With 10-year float design life, wide temperature range (-25°C to 60°C), and compatibility with all major telecom rectifier systems, they provide the reliability telecom operators demand.

10-Year Float Design Life

Reduce replacement cycles and lower total cost of ownership for remote tower sites.

-25°C to 60°C Range

Perform reliably in outdoor cabinets from desert heat to arctic cold.

Low Self-Discharge (≤3%)

Maintain charge during extended storage or infrequent cycling scenarios.

MSDS Certified Shipping

Safe international transport by sea and air to any tower site worldwide.

Telecom Base Stations FAQ

How many batteries do I need for a 48V telecom BTS?
For a standard 48V DC system, you need 4 units of 12V batteries in series (4 × 12V = 48V). For example, 4 × ND12-100 gives you a 48V 100Ah battery bank. For higher capacity, use 2V cells: 24 × NL2-500 = 48V 500Ah.
How long will Naradex batteries power a telecom BTS during an outage?
Backup duration depends on your load and battery capacity. A typical macro BTS consuming 2kW with a 48V 100Ah battery bank (4 × ND12-100 = 4.8kWh) provides approximately 2-2.5 hours of backup. For 8+ hours, use larger capacity batteries like ND12-200 or NL2 series.
Can Naradex batteries work with Huawei/ZTE/Ericsson rectifier systems?
Yes. Naradex batteries use standard voltage and terminal configurations compatible with all major telecom equipment manufacturers including Huawei, ZTE, Ericsson, Nokia, and their associated rectifier/power systems.
What is the recommended replacement cycle for telecom batteries?
With proper float charging at 25°C, Naradex ND12 batteries are designed for 10 years of service. In hotter environments (35°C+), expect 5-7 years. We recommend annual capacity testing after year 5 to plan proactive replacements.
Why source telecom batteries from a specialized manufacturer rather than a general battery supplier?
Specialized telecom battery manufacturers design specifically for standby float service, extreme temperature operation, and high-current BTS loads — requirements that differ significantly from automotive or consumer batteries. As a dedicated telecom battery manufacturer, Naradex engineers every design parameter (plate alloy, AGM compression, electrolyte volume) for the specific demands of outdoor BTS cabinets, including tropical heat, arctic cold, and frequent partial-state cycling. General suppliers often repurpose UPS or automotive designs that underperform in telecom environments.
