 How Superway DK DSF20 Works

The Superway DK DSF20 works by connecting the battery to the tester, which then applies a controlled electrical load (up to 20A). DK DSF20 9-99V 20A Lithium Battery Tester As the battery discharges, the tester continuously measures:

• Voltage level
• Current flow
• Energy output
• Total discharge time

Based on these readings, it calculates the battery’s actual capacity and overall health condition.

This helps users identify:

• Weak battery cells
• Reduced capacity batteries
• Fully healthy batteries
• Damaged or failing packs
