Which instrument applies a heavy load to a battery to evaluate its discharge performance?

• A. Carbon Pile Battery Load Tester
• B. Battery Analyzer
• C. Discharge Tester
• D. Load Tester

Answer: (A)

When you want to judge how a battery behaves under heavy current draw, you need a device that can impose a large, controlled load while watching how the voltage responds. The carbon pile battery load tester is built for this purpose. It uses a stack of carbon elements to create a high, adjustable load so the battery must supply a strong current. As you increase the load, you observe the terminal voltage decline and how long the battery can sustain it. That direct measurement under heavy discharge conditions is exactly what’s meant by evaluating discharge performance, giving a clear picture of remaining capacity and high-drain reliability. Other devices may measure health, impedance, or perform slower discharge tests, but they don’t provide the same rapid, high-current load needed to replicate demanding start-up or heavy-use scenarios like a carbon pile tester.
