By NLee the Engineer HALL OF FAMETOP 10 REVIEWER on October 13, 2013
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 (HK Digital Battery Tester Volt Checker for 9V 1.5V and AA AAA Cell 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.

__The digital read-out is plain to see, and provides the accuracy that other testers with readings shown as "replace" to "good", do not provide. Both "AA" and "AAA" are 1.5-volt batteries as fully charged, and will "read" as such, along with other similar types for placement between the adjustable red slider. Anything below an indicated 1.15 volts should be replaced. As always, weak and fresh batteries should not be mixed in any device. Nine-volt batteries (the kind commonly used in smoke detectors), are read from contact points on the top of the tester -not on the side. For these, the negative "female" contact goes to the left, as the tester is held with the adjustable red slider on your left. And contrary to what might be intuitive to some, batteries to be tested between the adjustable slider, must be placed "upside down", with their positive lead pointing to the base of the tester.
__In testing all batteries, hold in place a few seconds for the tester to indicate a true reading.

RECOMMENDED!

I use a HUGE number of batteries (Rechargeable and Otherwise).
I bought 6 additional different Battery Checkers over the last 12 months ALONE (Looking for smaller, easier ones than the large ones I have used for years). MOST ARE CRAP! Some work for a few months and DIE. Some are finiky and difficult to use. Some are not dependable and give you significantly different results two immediate tests in a row.
Some require a battery inserted and so are dependant on that battery.
In SHORT! THIS is the one you should BUY! I am about to buy THREE more of them! Save yourself all the hassels I went through ... your shopping for a relatively small, dependable Battery Checker is over!
{Did my Review help you decide?}

UPDATE: I just ordered a BUNCH more of them to give to family and friends!
Now that I have used it more ... I love it MORE THAN EVER!

I spent a significant length of time combing Amazon for a home battery tester, and I ultimately settled on the BT-168D for a number of reasons.

First and foremost, you don't need to be an electrical engineer to use the thing. You slide the red part up and down, and push on it with your thumb a bit for 2-3 seconds to receive a reading on the display. There were several multimeters and other devices available, but I remember attempting to use my father's multimeter years ago and never being able to understand what the giant turning knob represents nor what the dozen switches on the device do. Plus, there's no need to fiddle with the leads on wires (and heck if I know which two sockets on a multimeter to plug those into anyway!)

This model is superior in that you get an actual voltage reading as opposed to a needle on a generic good-to-bad scale, which can be problematic when testing items such as rechargeable batteries that will never test "good" on a fixed 1.5 volt scale. Most alkaline batteries output 1.5 volts and most rechargeables output ~1.2, so a tiny bit of research means the added precision of a voltage readout is a lot more helpful.

Most helpful is that this tester does not need a battery of its own to operate. A battery powered battery tester not only defeats the purpose of the device, it's completely redundant. Fortunately, this device uses the charge inside the battery you're testing to power itself.

The only problem I have with the device at all is that it seems to be designed for the left hand given the orientation of the moving part and the screenshots given.
