The battery tester I bought from eBay is simple and easy to use. This tester is value for money by inserting the AA, AAA, 9V and batteries of this type between the testing points and it shows immediately if the battery has enough power to work in the appliance or hasn’t the power available. The simple answer if this happens is to buy another battery from another simple and easy source such as eBay.

This is a hard one to try and stay objective, there is less variety of testers around now so this type has become more popular to locate and purchase but while it has good points there are some issues. On its good side price is the main thing, with a clear meter display makes for easy battery level checking also types that it covers makes this a versatile unit. It though has several points which cause me concern, mainly being the test current used which to me is very hostile to some battery types compared to those testers from an earlier time. This a personal view that a load is required for testing but not so much to add to its degradation or shortening of life. I am aware that a good test can show up things like a heavy test on a car battery will show up faulty cells by their gassing, also because most batteries now are higher powered with much larger capacity so loading can be greater as a result, my view would be less load but test for longer watching a meter trending that may drop lower during this time. On this point test current for 1.5v cells is about 0.4amps fine for most but maybe a little cruel for AAA sort, but over heavy for the standard carbon construction cells for which I prefer to say 0.25amp is better. This high current is also applied to those poor button cells which have not got 0.4amp to start with! Button cells to me would be about 1mA to say 5mA at most as these types are more designed to supply very low power for a good period of time. 9v also has a heavy load of 45mA which for lesser cheaper types is pretty much their capacity my option would be say 10mA to 15mA and watch the meter. For my purpose it became a modified unit using the meter to reflect these points I have made, I would say test your batteries quickly and not linger, plus avoid button cell testing unless you must check one which is a fiddle to do anyway and be quick. A viable tester otherwise, used with care at a great price what more can be said. Read full review

I check the batteries in a poorly performing device (camera, DAB radio etc) because it's usually only ONE of the batteries that is below par., NOT ALL of them. (The others are OK - no need to bin them yet!) ...Or it might not be a battery problem at all. This inexpensive gadget is great for checking most batteries, even 'button' batteries and those 9v square batteries (smoke alarm type). There is also a digital version, but I prefer this type with the needle & dial - which I find clearer rather than watching fluctuating numbers. So inexpensive I have 1 in the house, 1 in my toolbox, and 1 at my elderly Mother's! Recommended.

It works fine but you have to hold the Tester and the keep the battery in place to get a true result. When you place the battery on the fixed end and then slide the red movable connector into place it will not hold battery as shown, you need to hold the red slide in place. Fine for AA batteries as you can lay the tester on a flat surface but for AAA or larger batteries you need to hold them in place while supporting the Tester. Wouldn't buy another of this type.

I was quite surprised really, the quality is very good, given the price, but more importantly it works very well. I tested several battery sizes and types, and a couple of dud ones just to check, and sure enough they're all rated quite accurately. So, I'd be happy to recommend this, it really is a decent buy
