Nice economical battery tester
July 17, 2016
I bought this battery tester because I have a large watch collection in addition to being at least an average user of all types of other cylindrical and wafer style batteries. It has an easy-to-read selector switch for the type and voltage and a big needle and well written instructions that cover all battery checking situations. This instrument is a big help in identifying what battery I need to purchase next without wasteful "anticipatory" buying. It comes in a clear, tough plastic hang-tag card that can easily be modified into a permanent container that stores nicely on my workshop pegboard. This is great to have around the house to rule out dead battery issues with any device you are diagnosing or repairing. Two Thumbs Up.
  • Price will not break the bank. Big, easily readable needle indicator.
  • A closable box would have enhanced the purchase.

Affordable tool!

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.

As with another reviewer, I've also made the blister-pack the tester comes in its own storage case.

Impressive small tester
September 1, 2022
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.
Still better then a lot of other testers out there. Wish it had voltage readings though instead of good/bad.

Fun for the whole family

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.

Will it test 6V batteries? I use the small 6V that looks like a AAA half the size for a bark collar.

Yes, this will test 6V batteries.

Yes. It does 6v. It also does a few I have never heard of. Such as 4.5v. It does just about every battery there is. Not meant for 6v or 12v motorcycle or marine batteries though.
