Review: Invaluable piece of kit - This piece of kit is invaluable if you have a lot of batteries. I tested over eighty of my rechargeable batteries and found many to be near to useless. Easy to use and the spring loaded probes are nice to handle and feel solid in use. Dial in your battery type and attach the probes positive to + and negative to - it is as simple as that it tells you the current state of the battery and helps in deciding if the battery is nearing being useless.
Review: Slightly fiddly to use but built to last - Having had a couple of very cheaply made battery devices where the very thin wires they use snaps internally and you find you also need to buy a soldering iron, solder and a metre of spare wiring to be able to repair them. I thought I’d get one that has half a chance of lasting on it's own instead so chose the one someone else suggested in the review for a similar battery charger I’ve had in the past that had also failed on him. definately glad that I did. I agree you need a suitable surface to place the battery and battery tester on to or you’ll need 4 hands to hold everything in place while testing. The other type of battery testers don’t enabling you to test batteries far easier. Thankfully this comes with a short but a useful set of instructions , can’t vouch for the German and Japanese language instructions, but the English instructions were enough to be able to use the device. Worth reading through the instructions and keeping them to hand just in case, as with out you may come to the wrong conclusion. I’m no electrical expert so I’ve not a clue what the Ohmage means when I have an AA Alkaline battery reporting 1.39v along with 956m ohms. This device reports says the battery should have no charge but yet the battery works in my wireless mouse OK. It may be indicative that the battery I have may start leaking and fail sooner rather than later anyway, but also the fact the device I’m using will happy work with a battery down to 1.1 volts and can be used with either an alkaline battery as well as a rechargeable one. As I need to be able to check batteries and with this design of tester I’ve also been able to check desk plug fuses (handy when a packet burst and got mixed up with a few already dead ones) by adding a battery into the circuit gives me a much needed added functionality. This device definitely fills me with the confidence that it should last more than the typical 50-150 battery tests the cheaper hand held options (that don’t need additional batteries installed to work) typically last for. Thankfully the device comes supplied with 2 AAA batteries it needs. It also looked a lot easier to use than a standard volt metre device would have been. I can’t vouch for it’s accuracy but for my needs it enables me to be able to distinguish between a dead battery or one that needs charging and one that doesn’t or needs replacing, or I've got a dead wireless keyboard or mouse in a work environment.

### ⭐⭐⭐⭐ Also has impedence displayed
*by C***R on 2 May 2025*

Better than I had hoped but the text at each position is a little smaller than I expected. Reliably indicates the state of individual batteries and is accurate on button cells and pp9. The internal impedence function is really useful as it informs how good the battery is at delivering energy to higher powered devices. The higher the impedence, the worse the battery is even if it shows fully charged, it could be a duffer. Compare with a new one of the same type. Internal impedence means the battery will get warm, burning energy internally to overcome the impedence. In the pictures are used batteries that have different impedance. The last shows a brand new pp9 that has just under 1 Ohm at 934 milli Ohms. Most AA and AAA have less than 500 milliOhms if they're good. The Internet I a good source of info if you want to learn more.
