How to Test: Remove the batteries from the package and press firmly on the green dots on the label for 5 to 10 seconds. When tester screen remains completely black, less than 25% of the power is remaining. For the best results, test these batteries at room temperature (72 degrees F/ 22 degrees C). To avoid damaging the tester do not use fingernails or sharp object while testing. To optimize performance, do not mix new and used batteries. Replace all the batteries in the device at the same time.
