Battery TesterFor use with the following batteries; AAA, AA, C, D, 9V PP3 & all kinds of buttons cellsTechnical Spec;Handy, compact designNeeds no batteries to operateEasy to read analogue displayMoveable arm makes for easy compatibility with many batteriesSeparate side-by-side poles on the side of the unit for 9v PP3 batteriesSuitable for both rechargeable & disposable batteriesMeasures batteries under load for accurate readoutOverview - Made from lightweight but hardwearing plastic, this compact and easy to use battery tester is ideal for anyone who needs to determine the remaining charge in batteries of a variety of sizes, as it features a sliding pole design (as seen in the picture). You will now not need to use crocodile clips or specifically-sized slots. There is also a pair of 9v contacts on the side of the unit (cannot be seen in the picture), to allow the testing of “square” PP3 batteries.Features - The tester requires no power source or batteries of its own to operate, drawing power from the batteries you are testing. This has two benefits; firstly, that it will always be ready to use at a moment’s notice; secondly, that it measures the power while the battery is under load, giving a more accurate representation of how the battery will perform when part of a functioning circuit.A large analogue dial makes it easy to tell just how much charge remains in a battery, without the need for the necessary technical knowledge to interpret a digital readout. The colour-coded gauge couldn’t be more straightforward. Green is OK, red needs replacing.Additional InfoDimensions - 110 x 61 x 28mmWeight – 56gStandards - CE Compliant.
