FAQs
What types of batteries can I test?
The Sealey BT91/7 is designed for testing 6V and 12V lead-acid batteries, commonly found in cars, motorcycles, and vans.
How do I interpret the voltage reading?
A healthy battery should maintain a voltage above a certain threshold under load. Consult the battery manufacturer's specifications for specific voltage drop limits under load. Excessive voltage drop indicates a failing battery.
Is it safe to use this tester?
Yes, the Sealey BT91/7 is designed with safety in mind. The internal switchgear helps eliminate sparking during load application. Always wear appropriate safety glasses and work in a well-ventilated area.
Can this tester charge my battery?
No, this tester is designed for testing and diagnosing battery condition. It does not have charging capabilities.
What does 'load testing' mean?
Load testing simulates the demands of starting a vehicle by applying a controlled load to the battery. This allows you to measure how the battery performs under stress, revealing its true condition.
How do I maintain the tester?
Keep the tester clean and dry. Store it in a dry place. Regularly check the clamps and cable for wear and tear. Avoid dropping or subjecting the tester to impacts.
Troubleshooting
Tester does not show a reading.
Check the connections to the battery terminals. Ensure the clamps are making good contact. Check the tester's internal fuse if applicable.
Inaccurate voltage readings.
Make sure the battery is fully charged before testing. Clean the battery terminals to ensure good contact. Check for any corrosion on the tester's clamps.
Tester sparks during connection.
Ensure the tester's load switch is in the off position before connecting to the battery. Check for any damaged or exposed wires on the tester.
