Simyoung Analog Battery Tester, Compatible with AAA, AA, C, D, 9V Batteries, Model SY-100

this product works really really great and I even love the fact that I can test all of my batteries thank you

Not much to it, but it works. Hate putting batteries into a device and not knowing if the battery is good or bad. I keep this in my battery area for a quick test

I ordered this battery tester to replace my old one that quit working. It's perfect because it is smaller so it easily fits into my drawer. It tests multiple sizes of batteries, even button type.

Works like a charm. Arrived in perfect shape with no damage. Does the job to keep track with your batteries being good or not

Handy gadget, reasonable price. I tested it on 2 batteries - one new, one I knew was bad. Worked perfectly. Delivered 2 days after I ordered.

It appears to work well but is difficult to get battery lined up and apply pressure with only one hand to use. If the slot was bigger it may hold the battery in place better. But those of us whom only have the use of one hand are a minority.

it works but the battery slips out so hold on to it while you test it but the digital one is eraser to read for an exact read

i feel there need to put more information on how to use it. at least for older people and low vision oeioke, they need to work on people the delived it. because of my eye sight i did not see the one whole edge of the box has white paint of it. i got paint on my arm of my chair and my sleeve of my shirt shirt and counter top i was not very happy at all

surely, in 2021, someone has come up with an easier less awkward battery tester (I thought this was that). No such luck with this one.

Had trouble with it right out of the box. Tested a new battery first. First test it said the battery was completely dead. 2nd test, said it had a low charge. 3rd test, was barely in the good range. This happened with every battery I checked, new or used.
