100A Load Type Car Battery Tester

100A Load Type Car Battery Tester — Analog Dial, Real-World Load Testing

Unlike simple voltage meters, this 100A load-type tester applies an actual electrical load to the battery during testing — simulating real engine-start conditions to reveal true battery capacity. The color-coded analog dial gives you an instant pass/fail read at a glance, no screen or buttons needed.

Compatible Battery Types

• ✅ Flooded / Wet Cell lead-acid batteries (standard)
• ✅ 6V and 12V automotive batteries
• ✅ Motorcycle, marine, and agricultural machinery batteries
• ❌ Not compatible with AGM, EFB, or lithium (LiFePO₄) batteries

Compatible Vehicles & Equipment

Cars, trucks, motorcycles, boats, tractors, and any vehicle or machine with a standard 6V or 12V flooded lead-acid battery.

Typical Use Cases

• Auto repair shops: Fast, tool-free battery diagnosis — the analog dial shows results instantly without powering on a screen.
• DIY vehicle owners: Check if a sluggish start is a battery issue before paying for a shop visit.
• Used vehicle inspection: Apply a real load test to expose weak batteries that pass a simple voltage check.
• Marine & agricultural use: Rugged stainless steel housing handles workshop and outdoor environments.

Key Features

• 100A heavy-load test: Simulates engine cranking for accurate real-world capacity evaluation.
• Color-coded analog dial: Red / yellow / green zones — instant status at a glance.
• Copper alligator clamps: Secure grip and reliable electrical contact.
• Stainless steel housing: Durable and corrosion-resistant for long-term workshop use.
• Built-in switch: Simple one-step operation, no setup required.

How to Use

Clamp red to positive terminal, black to negative → flip the switch → read the dial. Green = good, yellow = marginal, red = replace. Test takes under 10 seconds.

Best suited for: Auto technicians, DIY mechanics, used car dealers, and marine or agricultural equipment operators.
