  • How Often Should Nickel Cadmium Batteries Be Refilled? Key Factors Affecting Water Replenishment Cycles

    How Often Should Nickel Cadmium Batteries Be Refilled? Key Factors Affecting Water Replenishment Cycles

    Aug , 14 2026
    Nickel Cadmium (Ni-Cd) batteries are widely used in critical power applications such as telecom systems, railway systems, industrial facilities, utilities, and emergency backup power systems due to their excellent reliability, long service life, and strong performance under harsh environmental conditions. Unlike sealed batteries, traditional vented nickel cadmium batteries require regular electrol...

  • Telecom Lithium Battery vs Residential Energy Storage Battery: What Are the Differences?

    Telecom Lithium Battery vs Residential Energy Storage Battery: What Are the Differences?

    Aug , 20 2026
    Lithium batteries are widely used in both telecom base stations and residential energy storage systems. Although both applications commonly adopt LiFePO₄ battery technology, their system design, Battery Management System (BMS) strategy, operating modes, and certification requirements are significantly different. Understanding these differences helps users select the right battery solution for spec...

  • -48V Power Supply Parallel Operation: Why Current Sharing Determines System Reliability

    -48V Power Supply Parallel Operation: Why Current Sharing Determines System Reliability

    Aug , 25 2026
    Quick Answer When multiple 48V power modules are connected in parallel, adding more modules does not automatically improve system reliability. The key is whether the modules can share the load properly. Current sharing, N+1 redundancy and dynamic response determine whether a modular power system can operate stably during expansion, failure and maintenance. Key Takeaways Parallel connection increas...

  • Why a Running Fan Does Not Mean Your Power Supply Cooling Is Working Properly

    Why a Running Fan Does Not Mean Your Power Supply Cooling Is Working Properly

    Sep , 02 2026
    Quick Answer A running fan only shows that the fan is operating. It does not mean the power supply is effectively cooled. Actual cooling performance depends on airflow, air pressure, ventilation design, ambient temperature, and installation conditions. Long-term high temperature can accelerate component aging, reduce available power capacity, and shorten power supply lifespan.   Key Takeaways...
