    Testers & Detectors Information
You rely on your batteries, so you need to know how much charge they have. A cheap battery tester will tell you when they need to be recharged or thrown out. You can find two different types of battery testers. The traditional analogue testers are good enough for some uses, but a digital tester will give you a precise reading. If you buy batteries wholesale, you will need to test many to make sure they are still fresh. A battery tester will help you get this job done quickly. Look for a tester which will adjust for different battery sizes for the greatest flexibility.
