Tells me what I need to know

This works just fine and is sturdy enough that I feel it will last a long lifetime. My only complaint is that a battery that is too weak to run some heavier-drain devices still registers in the "good" range. That is, a battery that is clearly on its way out still registers at 90% on its readout. But once you know that, you can pretty well judge the battery's draining state, even if device says "good".

Pros
  • ★ QUICK RESULTS: Simply place a battery into the decent battery detector, it will shows you quickly the status of your batteries’ health by the using bars, helps you avoid battery damage from unnecessary recharges. DON'T POWERED BY RECHARGEABLE BATTERY NOR TEST RECHARGEABLE BATTERIES
Cons
  • The tester may give false positives or false negatives for certain battery types

Worked very well: my feedback

I had 3 battery testers and they all did not work for some reason. This one worked very well. I really love it. That's my feedback!

Pros
  • Accuracy - the LCD display provides accurate readings of the voltage and remaining capacity of your batteries, enabling you to make informed decisions on whether to replace or recharge your batteries
Cons
  • The tester may be relatively heavy or bulky compared to other battery testers

Great product for my opinion

As a photographer, I use tons of batteries for my flashes and triggers at weddings and on shoots and when the flashes start to not cycle as fast or misfire, I need to throw out my batteries and put in new ones. Well I typically don't throw them away, I just store them to use in lower powered things like computer mouse, etc. But I finally got something that helps me know weather the batteries are dead or still good. This product will save me money in the long run. I love it, works great

Pros
  • Takes all sizes of batteries, Just put them in and read display!
Cons
  • The tester may be relatively expensive compared to other battery testers

Very Useful on my review.

What's not to like? It works great, it's easy to use, and it accommodates numerous battery types.The only "complaint" I have is a minor one. The markings that tell you what battery type go in each slot are pretty small and the same color as the gray plastic, making it hard to read. It's still 5 stars from me. I'm always finding loose batteries around the house and this has been really useful for me in determining which ones are still good.

Pros
  • ★ HIGH COMPATIBILITY: It is not only suitable for AA, AAA, C, CR123A, D, 9V, N, CR2, CRV3, 2CR5, CR-P2 cylindrical battery testing, but also good for checking a wide variety of button cell batteries
Cons
  • The tester may not be able to test batteries with unusual chemistry or construction

Great product good for me

Quick & Easy to use. Let me get rid of many old batteries that were just to weak to keep.I would buy it again! Thanks for attention.

Pros
  • An easy way to check almost all of your most commonly used batteries. A truly good product.
Cons
  • The tester may not be able to test specialty batteries, such as those used in watches or hearing aids

Don't WASTE YOUR MONEY 💰

I'm showing in my photos the same batteries being tested in another tester that is very accurate, and I have tested the batteries with a multimeter also and the batteries are no good, but this Dlyfull Tester shows the battery is Good.It's RUBISH AND VERY MISLEADING.

Pros
  • Great battery tester at a great price.
Cons
  • The tester may not provide any analysis of the battery's internal components or health

Easy to use for my opinion

Good tool for measuring battery strength of a variety of household batteries. It comes with a hardcopy that provides basic information, but it would be more helpful if each testing slot was more clearly marked with the applicable battery type.

Pros
  • It was difficult to figure out how use. Better instructions would be helpful.
Cons
  • testing batteries. i suggest you use a different supplier. Also I want my money back

So easy to use and store

I use this often to test my remote batteries. so easy to use and lets me know quickly when the batteries go from strong to weak,

Pros
  • Let us sort out the good batteries from the bad.
Cons
  • The tester may not be compatible with all brands of batteries

It doesn't work in my review

After carefully reading the instructions that indicated that the contact protective tab on the provided battery needed to be removed, I found there was no tab and the battery wasn't seated. After popping the battery in, the device didn't work. At all. Nothing. Nada. So I replaced the AAA battery with several fresh ones in succession and found that none of them brought the device to life. So much for using a tester to cut down on buying unnecessary batteries. This isn't the solution, just more…

Pros
  • Battery Testers
Cons
  • The tester may require the user to have a steady hand to properly insert and remove batteries

Great for small battery testing

Appears accurate with the five types of batteries that I have tested. Easy to read display and easy to use. That's my review.

Pros
  • Every household should have one of these. Saves time, saves money!
Cons
  • The tester may not be accurate if the batteries are partially discharged

I like the design and digital readout

I like the design much better than other models. That are basic models. The readout is nice do use is much simpler than a spring loaded clip.Looking forward to see how long it’ll last.

Pros
  • {}
Cons
  • The tester may not be able to distinguish between different grades or brands of batteries

Not accurate: my feedback

Tested 30 batteries, many of which have stopped working. The reader shows these batteries as nearly at the top of the "Good” scale. Also, it would be a novel idea if the battery types were labeled on the tester.

Pros
  • Compact and Portable - the size of this battery tester makes it easy to carry around with you, making it perfect for use on the go or when traveling
Cons
  • The tester may not have a warranty or customer support available for those experiencing issues

Easy to use on my review.

My 90 yo father with dementia spent all day testing every battery he could find. It was easy for him to use, had a blast using it and it made him feel useful. He loved explaining to us how to use it! B

Pros
  • It is easy to use and cover a lot of different battery sizes.
Cons
  • The tester may not be able to test batteries that are already installed in a device

dlyfull battery Tester is very versatile

This tester will fit just about every battery, including a few that I have never heard of. I would hae been nice to more clearly show a + and - symbol on the tester.

Pros
  • Very happy to find battery enclosed. Very easy to use.
Cons
  • The tester may be difficult to operate for those who are not technologically savvy

Revainrating 5 out of 5

Works perfectly.: my feedback

Easy to hold while checking battery. Round flat cell batteries and 9 V batteries easy to check. Just what I was looking for. No more throwing batteries away I'm not sure of.

Pros
  • Electronics
Cons
  • The tester may not be able to test for the presence of leaks or corrosion

Shows Many Batteries "Good " When They're Not

This tester is easy to use and the scale is legible and logical. However, for many batteries they will still register near the top of "Good" when it's clear from what they're had to be removed from that they're not. This is particulary true of CR123A batteries. Frankly, I have never had any bad battery register as "weak" or "poor". Is this device truly measuring resistance in the battery or is it just confirming residual voltage?

Pros
  • Household Batteries, Chargers & Accessories
Cons
  • The tester may require certain batteries to operate, which may not be included with the purchase

Good, but could use some improvments

Overall, the tester isn't bad. LCD screen can be hard to read in brighter light. And I question the accuracy. A used battery (AA .9v as tested with multimeter) displays full bars, same as a brand new battery. Take this for what its worth.

Pros
  • good quality and easy to use
Cons
  • The tester may not work properly if the battery contacts are dirty or corroded

Battery Checker - my new review

This is so easy to use and easy to read. I like it so much that I ordered it also for my daughter. I highly recommend it. The tester may not be able to test batteries with odd shapes or sizes.

Pros
  • WORKS GREAT
Cons
  • The tester may not be able to test batteries with odd shapes or sizes

Revainrating 5 out of 5

good tester on my review.

Only had a few days but much better than my 1990's era tester. Solid, good size and gives you full granularity of battery voltage vs. old red/yellow/green lights.

Pros
  • So far so good looks to be accurate, pretty easy to use
Cons
  • The tester may not provide any information on the health of the battery aside from whether it is charged or not

Revainrating 5 out of 5

no more doubt in my review

dont have to guess anymore.battery may be to weak for one device but plenty strong enough to use for something different for a while

Pros
  • works perfect
Cons
  • The tester may give inconsistent readings over time
