Flexzion Universal Battery Tester - Digital LCD Voltage Meter for AA AAA C D 9V 1.5V Button Cell Batteries with Adjustable Arm | Easy to Read Display | Perfect for Home, Office & Emergency Kits

Does the job, easy to read digital readout, works as advertised, no complaints.I had one of these and misplaced it so ordered a couple more. I've tried several different battery testers and this is still my favorite. The others with a needle meter seem to go bad in time, then the needle bounces back and forth. This digital meter, gets to the numbers quick. I especially like to use it on my rechargeable batteries, it let me know if they discharged or not while sitting in storage.There was no instruction sheet. The unit description says "load test" but no where else. Not in the product description or additional facts on the Web page..There is enclosed no product specification sheet or explanation sheet enclosed. Does it do a load test? If so, what is the resistance of the load? Is it the same for all batteries? What is the current that is needed to show "good"? The back of the unit shows the voltage that is required to show good, but it is useless if there is not load. But nowhere does it state that there is a load presented. So, if I don't see a declaration, I presume there is none.I received this product in a timely manner and it is exactly what I needed. I had several loose AA batteries that I had no idea if they were good or bad! This tester told me that I had several good batteries that I had planned to throw away. I will use this in the future and am so glad I purchased it.IT WORKS FOR ALL BATTTERIES AND IS EASY TO USEWorks on everything! I was able to go through drawers of batteries and pick out the good ones quickly.Slightly cheapish construction. You get what you pay for.Works goodTenia muchas pilas guardadas y ya listas para irse al reciclaje, pero con el probador que acabo de adquirir me puese a revisar cada una de ellas y cual fue mi sorpresa que muchas de ellas eran nueva.Lo malo es que en el paquete de dos uno no sirve y con la experiencia que tengo,mejor me lo quedo porque perderé el producto y mi dinero jajajafonctionne bien. Mercithe device works great and cost was fairAll perfect!
