Great little battery tester!

Solid state, no pesky wavering needles or other moving parts -- its LED display is far superior to those types. Self-powered by the battery it's testing. Very accurate and reliable so far. I only use mine for AA and AAA cells, both NiMH and alkaline -- there's a switch to set it for rechargeable or primary batteries. I like it so much I'll probably buy another to keep in my camera bag -- it's so small and lightweight it can be tucked into practically any camera bag.

Breaks far too easily

In my line of work, I need to check batteries on a daily basis, about a dozen AA's each time. I bought one of these on [...], and it broke on me the very next day. The metal prong on the negative end lodged open, and when I tried to gently pry it loose, it snapped off. Luckily, the seller replaced it for me free of charge. The replacement only lasted a few weeks, though. Even treating it with kid gloves, the same thing happened: the prong stuck, then broke off when I just tried to gently shak...

If they could fix this design flaw, it would be a very good tester, but as it stands now, I would only recommend it for VERY infrequent use.

The best but not indestructible

Use this daily. The copper contact on the left will eventually break off from metal fatigue. Simple limitation of the material physics. Super tester.

How much power do you have?

By

from Lake Tahoe, NV  -  Semi-Professional

I was a skeptic until I started checking a collection of batteries I planned to dump in an electronics recycling bin. To my surprise most of the batteries still had plenty of power. Yes, I still prefer fresh batteries when starting a project, but this unit makes it easy to determine if batteries are worth saving as spares or for use in other devices. Plus, it works with a variety of batteries.

Compact, efficient

Most useful for AA and AAA batteries. Not sure yet how to check cr123 batteries. But I bought this to check the former, so that's ok.

Great tester but breaks far too easy

By

from Nashville, TN  -  Quality Oriented

I bought one of these on and it broke on me with a few weeks use. The metal prong on the negative end lodged open and when I tried to gently pry it loose, it snapped off. I've been able to still use it by shorting the negative side to it's connector with a paperclip instead. Not ideal but it works.

Favorite Battery Tester

By

from Lansing, MI  -  Semi-Professional

After much web research, this was the only battery tester I could find that both places the tested battery under a load (the proper way to test) and did not require a battery to be installed inside the tester in order for it to apply a load to the tested battery. Another valuable feature is a switch to test either Alkaline or Rechargeable batteries, which I assume changes the load threshold for the expected voltage difference between those two types of batteries (1.2 versus 1.5 volts). It tests AA, AAA, and 9-Volt batteries. If it could test C and D batteries as well, it would be absolutely perfect. I still gave it 5 stars because I rarely need to test those two sizes, and it does a super job of testing the batteries I use most. I bought three of these testers so I can keep a tester in my office, home, and luggage for travel.

For the money, my favorite tester

By

from Patchogue, NY  -  Hobbyist/Enthusiast

I needed a small,light-weight battery tester to carry anywhere(basement, garage, house) for a quick test of some battery powered equipment not working right. And it tests rechargeable and standard batteries, you just have to push a switch for each of the types. You install the battery and it will show all the lights for a second if the battery has a charge, then you have to wait (a few seconds) as all the lights go out. Then lights will come on depending on the power left in the battery.
