About this product
The Faithfull Battery Tester is a compact analogue device for checking the charge level of standard domestic and rechargeable batteries. It suits anyone who relies on battery-powered tools and wants to confirm batteries are ready for use before fitting them. An easy-to-read analogue needle display shows whether a battery is good, low, or needs replacing. An adjustable arm accommodates D, C, AA, AAA, 9V 6F22 and 1.5V button cell batteries, and folds down for compact storage, such as in a toolbox or site bag. The tester is powered by the battery being tested, so it needs no external power source. Test time should be kept short to avoid unnecessarily draining the battery under test.
