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

The media could not be loaded. I recently chose this battery tester based on good reviews and its reasonable value for money.The device is primarily made of plastic, is very lightweight, yet adequately solid, and fits comfortably in the hand. The red slider adjusts up and down for various battery sizes.It does not require any additional power to operate; the batteries being tested power the LED lights when the contacts are touched.On the back, there is an embossed chart displaying the voltage ranges corresponding to the LED power indications. This is useful for those who want to know more specific technical details.The display has seven LEDs, with only one illuminating at any given time. It has a range of three in both the green and red zones, with one yellow LED in the middle. Therefore, if any of the green LEDs light up, the battery should still be functional, but with lower power as it nears the left side of that zone, and so on.I tested all battery types (see attached video) except for D, as I didn’t have any, and received a reading in each case, indicating it works as intended. Sometimes, you may need to slightly adjust the battery between the metal contacts a couple of times to obtain a stable result.The advantage of this device is that it allows you to sort through numerous old batteries quickly. Some may indicate they are fully powered, while others are ready for disposal, for example when a remote starts to malfunction, it could simply be one of its two batteries needing replacement rather than both. Also, some batteries I tested were in the yellow or lower green zone, so pairing them into one device could help ensure they eventually run out at roughly the same time, and then replace both with new. All good so far.-Pros:• Good value for money• Works as expected• Easy to use• Good accuracy/readability• Nice, simple design• Tests six battery types• No additional power required-Cons:• Button cells can be fiddly to secure between contactsOverall, this is a great little device that is easy to use, and may eventually pay for itself if you have a kitchen drawer full of old batteries with unknown potential. I am happy to recommend this, so it’s five stars from me.Thanks for reading, I hope you found this review helpful

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 levelsCons:❌ flimsy material❌ slider stiff on first use

Really simple to use and is great for checking batteries- particularly iseful to work out if a toy is broken or if it just needs new batteries. Simple light up scale is bright and works well.

Great little device. Immediately you can see if an issue with a remote or torch is down to the batteries or the product itself. Enabled us to test all of the batteries that had been around for a while and throw out the ones that were no good.

simple to use, can now test all my batteries (especially christmas toy ones!) and not throw away all of them. saves so much money and time

Prompt delivery, adequately packaged, simple device that doesn't need any of its own batteries to work so always available for immediate testing. LED lights are clear and give a reasonable indication of remaining charge. Works with disposable and rechargeable batteries. Probably not rugged enough for commercial use but a great home aid.

handy item which registers good/poor strength.saves time trying batteries in and out of the appliance

Difficult to hold the battery in place with old hands but it does work.Not very well made but it was cheap,will it last.
