Product Information
Full details
This Faithfull Battery Tester is designed for homeowners and hobbyists who want a quick and easy way to check the charge level of common household batteries. Its primary benefit is providing a clear, analog indication of battery status (good, low, or replace), preventing the use of dead batteries and helping you manage your power sources effectively. A key consideration is that the tester itself draws power from the battery being tested, so test times should be kept brief to avoid unnecessary battery drain. It accommodates a wide range of battery types including D, C, AA, AAA, 9V 6F22, and 1.5V button cells with an adjustable arm for secure placement.

FAQs
How do I know if a battery is good, low, or needs replacing?
The analog needle will point to 'Good' for a fully charged battery, 'Low' for a battery with reduced charge, and 'Replace' for a battery that is depleted and unlikely to power a device effectively.
Does the tester need batteries?
No, the Faithfull Battery Tester is activated by the battery you are testing. It draws a small amount of power from the battery being checked.
How long should I test a battery for?
To avoid unnecessary battery drain, keep the test time as short as possible, typically just a few seconds until the needle settles.
Can this tester test rechargeable batteries?
Yes, it can test most types of standard domestic and rechargeable batteries within its specified size range.
What types of batteries does it *not* test?
The tester is designed for common household batteries (D, C, AA, AAA, 9V, button cells). It will not test larger batteries like car batteries or specialized power tool batteries.
Is the needle reading precise?
The analog needle provides a general indication of battery status (good, low, replace) rather than a precise voltage measurement. It's intended for quick, practical assessments.
How do I store the tester?
The adjustable arm folds down, allowing for compact storage. Keep it in a dry place.
Troubleshooting
No needle movement when testing a battery.
Ensure the battery is correctly inserted, making firm contact with both the adjustable arm and the base contacts. Check that the battery itself is not completely dead, as the tester requires a minimal charge to activate the needle. Try testing a known good battery.
Needle consistently reads 'Low' or 'Replace' even with new batteries.
Verify that you are using the correct type of battery for the tester's contacts. Ensure the battery is oriented correctly. Clean the battery contacts and the tester's internal contacts with a dry cloth. The battery may be a low-quality one or have a manufacturing defect.
Difficulty fitting certain battery sizes.
Adjust the arm to its full extent to accommodate larger batteries like D cells. For button cells, ensure they are placed flat on the contact and the arm is gently lowered to make contact without excessive force.
