RDBT-3018D Battery Discharge Tester discharges the battery pack through the built-in load. The Battery Load Discharge Tester can meet the discharge test of battery pack with various voltage levels (0~300V). The tester can monitor the battery voltage, discharge current, discharge time, discharge capacity and other parameters in the discharge process in real time; It is applicable to activation discharge of various storage batteries, discharge during initial charging of storage batteries, maintenance discharge of storage batteries, and inspection of storage performance and load capacity of storage batteries; The utility Battery Discharge Tester has the advantages of simple operation, safe discharge, etc.


  •  The test voltage range is wide, covering the 0-300V voltage range battery pack discharge test, the maximum discharge current reaches 150A, one machine covers 5 voltage levels, and it can meet the battery pack test of multiple voltage levels (12V/24V/48V/110V/220V).

  • The product uses customized nickel-chromium alloy resistors as the load source. Low resistance value; can achieve a larger current discharge, customized appearance makes the power density higher. High precision; accuracy can be controlled within ±0.001Ω, as a load source to make the discharge process more stable. Low temperature coefficient; little influence by temperature coefficient, strong environmental adaptability. Resistant to current impact; strong current resistance, can quickly respond to large current impacts, and the discharge process is more reliable.

  • Smart chip control. Intelligent control of the discharge process, automatic adjustment following the drop of battery voltage to ensure constant current discharge. The voltage of a single battery is collected in real time and displayed in a curve manner, which is convenient for evaluation and analysis. At the same time, it intelligently analyzes the battery voltage status and makes an evaluation. Intelligently calculate the conversion between the discharge capacity and the discharge hour rate to achieve the best evaluation effect of the battery capacity status. A variety of threshold thresholds can be set, intelligent judgment.

  • 7-inch large LCD touch screen: It adopts a 7-inch large-size bright touch screen with a resolution of 1024x600, which can be clicked directly on the screen. It is simple and clear, with strong anti-interference ability.

  • Automatic discharge current calculation function: built-in discharge coefficients for each hour rate, which can automatically calculate the discharge current that needs to be set according to the nominal capacity of the battery under test and the required discharge rate.

  • During the process of battery charging and discharging, the voltage of each cell is detected and displayed in real time: the track of each cell voltage histogram is displayed on the host screen, and the data table is supported. It can also automatically display the cell with the highest and lowest voltage in real time to help you quickly analyze the trend of individual changes.

  • Charge&Discharge curve view: The voltage and current curves of the battery pack during the charge&discharge process can be reviewed.

  • Data transfer: The host is configured with U disk for data transfer, and the data analysis software can analyze the data and support report generation.
