Kaiheng Battery Load Tester | 6/8/12/16/24V Car Battery Diagnostic Tool

Overview

Meet the Kaiheng Battery Load Tester, a compact diagnostic companion designed for quick, real‑world checks of battery health and charging performance. Built with a sturdy housing and a simple interface, it helps you understand whether a battery can deliver the cranking power your vehicle needs. Use it in the garage, at home, or on the go to gain clear visibility into battery condition without guesswork.

Why this tester stands out

• Fixed load current ensures consistent testing results: 100 A for 12V batteries and 50 A for 6V batteries.
• Voltage readings are precise: accuracy within ±0.2 V for straightforward interpretation.
• Rapid 10 second test window mirrors starter motor draw to reveal potential weaknesses before a failure.
• Portable and DIY friendly, suitable for cars, trucks, SUVs, motorcycles, RVs, boats, and more.
• Safety features include an insulated carry handle and color coded copper clips for confident terminal attachment.
• Smart design with a perforated housing to promote ventilation and stable operation under use.

How it works

Attach the copper clips to the battery terminals using the red positive and black negative grips. Apply the load via the switch and hold for up to 10 seconds to simulate starter motor consumption. Read the voltage during the test to infer battery condition and charging system behavior in real time.

What you can test

• 6V and 12V battery systems for a wide range of vehicles including cars, trucks, motorcycles, boats, and RVs.
• Starter and charging system diagnostics to spot patterns that may indicate wear or insufficient power delivery.

Design and safety

The tester features a durable housing with a perforated surface for ventilation, helping to keep temperatures in check during use. An insulated carry handle makes it easy to move between workspaces, while the copper clips with red and black grips guide correct connection and reduce guesswork.
