5.0 out of 5 starsSimple and effective tester for both alkaline and NiMH batteries
By NLee the Engineer HALL OF FAMETOP 10 REVIEWER on October 4, 2014
A traditional inexpensive battery tester consists of an analog meter with Red/Yellow/Green zones. If the needle moves into the Green zone, the battery is said to be 'Good'. If the needle stays in the Red zone, the battery is considered 'Bad'. One problem is that since the tester is calibrated for alkaline batteries, it does not work correctly for rechargeable NiMH or NiCd batteries. Even a fully charged NiMH battery will end up in Red or Yellow zone, because it has a lower operating voltage than alkaline battery.

- A fresh alkaline battery has a voltage reading close to 1.6V. The battery voltage drops linearly with usage. By the time it drops below 1.3V, the battery is about 50% exhausted.
- A freshly charged NiMH battery starts from around 1.35V. During operation, its voltage remains fairly constant at around 1.2V, until the battery is nearly exhausted, and then the voltage falls off rapidly.

This product (HDE Universal Digital Battery Tester BT-168D), on the other hand, has a digital readout for battery voltage. Based on the voltage reading and the battery type, the user can make an informed decision on the battery status.

For example, if you put a NiMH battery in this tester and it shows over 1.25V, the battery is fully charged. If it shows less than 1.20V, the battery is nearly exhausted. The difference between 'full' and 'empty' is just 0.05V, which is why traditional battery testers are useless in reporting the status of rechargeable batteries.Read more ›

4.0 out of 5 starsGood product
By E. Wolf on October 6, 2014
Verified Purchase
This is a good product; easy to use and accurate; I have read some of the other reviews that complain that it is too hard to manage, and I can see the point if you have problems with manual dexterity--like arthritic hands--but for healthy hands it should be easy to manage. My only complaint is that the plastic seems a little brittle--I suspect that if dropped on a hard surface the plastic might crack. To be fair I haven't dropped it yet.

5.0 out of 5 starsWorks perfectly
By Mark K on May 30, 2015
Verified Purchase
Despite other reviews that suggest it is cheaply made, due to its weight, I've had no issues with this unit. I have been able to get a reading on every battery that has been tested, and the readout is clear and easy to read. As for the plastic used in the body of the unit, it appears to be a high impact plastic. A simple drop from 3 or 4 feet should not be enough to break it.

My only complaint with the unit is that the reference sticker (on the back) could be made larger. While I can read it, it seems a bit small given how much room is available.

5.0 out of 5 starsSo far, so good
By Eastern Shore on November 13, 2014
Verified Purchase
So far, so good. I had another tester from Amazon that worked great for a year or so and then just decided to rate all batteries at 40% regardless of whether the batteries were brand new and worked perfectly in a flashlight, for example, or whether the battery was low--everything got 40%. This battery tester is doing a great job of testing but I say, So far, so good, because the other tester was great at first, also. I will revisit if this tester goes bad.

4.0 out of 5 starsGreat little tester for the price.
By Derek Niehaus on September 25, 2014
Verified Purchase
I use an audio recorder a lot, and I sometimes switch out batteries before the device says they're low, just so it doesn't die in the middle of something I am recording. I bought this to test all the batteries I have to see which are good and which are not. So far, this product has done an excellent job of that. It is kind of cheaply constructed. That's the only negative I have to say after about 2-3 months of owning it. I would recommend it!

4.0 out of 5 starsHDE Universal Digital Battery Tester - For AA/AAA/C/D/9V & Mini Cell
By Granny Gems on December 9, 2014
Verified Purchase
This works well as stated in the description. A little difficult to hold the smaller AA batteries as you test it because one hand/fingers have to hold it in place while the other hand slides the red connector to read the results. It would have been easier for me to read it if it had been reversed, or if it could be laid flat on the counter. Would be 5 stars otherwise. Price was right and it works!

I was a little nervous after reading the reviews, but it works! Not the best made product, but you get what you pay for. I preferred the digital readout, and so far it seems accurate. Great price!
