I dont understand how you test AAA batteries. There is no way to have the top tester touch the battery top with the bottom touching at the same time.

You have to hold the AAA battery at a angle to reach the top portion of the tester it does work though.

You must hold AAA batteries leaned out at an angle to make proper contact between the tester and battery.

You can check voltage , but u can't do a load test to confirm battery condition !

How would I go about conducting such a test? I don't think it would be worth the time and/or effort to do it.I also have a pair of these batteries by Philips, and a pair of Rayovacs, and two devices that use them, and I don't find any noticeable difference in performance.

I have not used this particular product. To test batteries you need to know more than just what the voltage is, you have to know the voltage drop of the battery when a load is supplied. If your talking about a car battery places like Autozone will check your battery for free.http://hyperphysics.phy-astr.gsu.edu/hbase/electric/dcex6.html

We generally just use multimeters and/or Hydrometers to check batteries, I don't think this has that capability.It's great for charging though.

If the 18650 batteries are charged, then there might be a problem with the switch or the the connection between the batteries and springs, or the spring and the LED. You might have to pop the thumb switch cover off and try making the connection manually to test it.

There is a little clip that you push the AAA batteries against when you put them in.Look closely and you will see them. Hope this helps

make sure you are pressing the metal on both hands. I thought our batteries were dead, too. but they were not. My next thought was to take the battery out and check the size, but that wasn't necessary.

I'm not sure as I have only tested standard batteries but I think lithium can be tested as well.

Measure it with a voltmeter. Or use a battery tester. You can get a multimeter (measures volts, amps and ohms) for as little as $15. Then have someone show you how to use it. Its not hard and it's fun. Many other uses such as checking continuity, troubleshooting your car, checking electrical sockets, etc.

the AAA batteries fit, at first I had this issue too but there is a certain method to inserting them and once you figure that out then it works fine.

Double check that the batteries are in the correct way and place the module in with the pointed nub towards the light. If that doesn't work check the voltage on each battery just in case one is bad. Then check the voltage on the battery module to make sure that it isn't faulty. Sometimes those 3 x AAA battery modules are just faulty. Hope this helps.

I can find nothing in the directions about the device not being able to test lithium batteries.

Mine was the same way. You have to check the connections of your battery. It has a piece of plastic where the batteries are placed which keeps the batteries from connecting. You have to break a piece of the plastic off where the battery connects so it will make a connection.

You might have a bad battery. A cell can be intermittent and the voltmeter will still read okay, since it doesn't check current. I suggest you test each battery with a battery load tester.

The issue is charging current, as the charger doesn't sense capacity. If you only charged one AAA, the charge rate would be too high, .75 mA. This is why the instructions specify that at least two AAAs or 10440s be inserted when charging.

As far as I know, no. To test the charge, it is executed a discharge/charge cicle. It would be possible to test the volts of the battery, wich is reliable mesasure for non-rechargeable batteries, but I presume it would be dangerous.
