LED Digital Battery Tester Battery Checker Multi Size for AA AAA C D 9V 1.5V Button Cell Batteries (Requires No Battery to Operate)

Very good little battery tester, I've saved a ton of old batts that I found when doing a family house clearance, nearly all are good to the batter tester was well worth the cost. Easy to use, and nice bright indicator light. Very useful that the item itself doesn't need a battery.

Arrived very fast with prime, so I was able to test the leftover batteries I had quickly giving me time to order some new ones. Yes the tester feels a little cheap and lightweight, however this works in its favour keeping costs down as it was well priced. It worked relatively well and is nice and compact to keep in a drawer. The red slider is a little stiff but I think it will loosen up with longer use. Some batteries didn’t light up the device, I can only assume they were very dead. I had lights for all colours indicating good, low and empty batteries. Is it very easy and straightforward to use. Pros: ✅ small and compact- easy to store ✅ cheap but works ✅ easy to use and read the battery levels Cons: ❌ flimsy material ❌ slider stiff on first use

Very useful gadget and reliable. I have many batteries which I thought were dead which are actually nearly full, and this little gadget has enabled me to identify which are actually dead and which can still be used.

Great product, it’s so simple to use, just move the red slider to the battery being tested, AA for example, slot your battery in the gap and it will instantly show you if the battery is Good, Low or needs replacing. I went through all my Xmas batteries I used, that I thought were no longer any good and found 75% to be good. The green good section has 3 levels which shows how good the battery is. Just pair up batteries of the same level and no more throwing away batteries that have life left in them. This little gadget has saved me a lot of money and worth every penny. Definitely recommended this.

My trustee tester ceased employment. I chose this one to replace it. Happy with the product. Easy to use and accurate.

The idea of the product is great but unfortunately this design seems flawed. I had almost the exact same design (non LED type) that came with a “battery daddy” battery storage box from Costco. That one actually lasted much longer than this one. If it’s the same design, then the wires inside are extremely thin and don’t handle movement well, maybe I just got a lemon, but won’t be going for this design again.

Only just received this and have used on AAs and AAAs so far but seems a great improvement on our old (equally basic) battery tester. Easy to use, positive and consistent results and doesn't need its own batteries. Feels a bit light and flimsy but it is cheap. Does the job so happy with it.

Bought to check 9V smoke alarm batteries as as we all know they seem to always beep in middle of the night.... changed the low readers and have had no 2am drama's since :-). Also works great with re-charge AA's
