I have a need for constantly checking the state of charge on batteries. Most cheapo battery testers don’t put an actual load on a battery and therefore can give a false sense of the actual ability of a battery to run something.

I had a particular experience that will always drive this home for me. I was working on the movie ‘The Scorpion King’ as a sound technician and we had to put a radio mic on one of the actors, possibly the Rock (Dwayne Johnson), I can’t remember. The battery looked fine on a non-load battery tester, but the radio mic just didn’t fire up. We then checked the battery on a unit with capabilities like this one and you could see the needle drop from good to dead quite rapidly. Problem solved: Bad Battery!

I love this little thing - it's inexpensive and easy to use, and is good for so many applications.

I currently have it stored with my watch repair kit and spare rechargeable batteries, but I will be picking up a couple more to put in my garage and also portable tool-kit, too.

Sweet little battery tester that gives better readings since it adds/incorporates resistance. Nice sturdy plastic & clear analog display. Ability to test numerous types of batteries, even coin types. Cannot test the newer lithium ion rechargeable batteries like 18650,14500,16340, etc.

It works well and the kids enjoy using it to test batteries as we have a lot floating around. The analog gauge makes it interesting for them as nearly everything else is digital.

Simple and easy to use for the 5 and 7 year old!

The Gemoro Econotester tests MANY varieties of batteries; even button batteries.
First, turn the center switch to the type of battery to be tested. (see picture--it is set to 3v)
Next, just touch the RED cable to the positive terminal and
the BLACK cable to the negative.
The screen--easy-to-read- shows the strength of the charge.
