I've had a Sears bolt tester for household batteries forever. I can't even imagine it must've been at least 30 years and it finally stopped working so I went online and of course, I thought of Walmart and found something extremely similar and more reasonable than I thought it would be and I purchased it. First thing I did was test my batteries and it works perfectly exactly like my 30-year-old Sears one!!!

walmart.com

Appears to work just fine.  Unlike many inexpensive battery testers,  the GB Gardner Bender GBT-500A applies a load appropriate to the type of battery being tested.  This makes for a much more valid test, compared to testers which rely only on a measurement of the open-circuit voltage.

Gardner Bender GBT-500A Battery Tester

This battery tester is much more accurate than the previous inexpensive tester I was using.

This is an excellent and versatile battery tester that can test many different types of batteries, including button cells.  I highly recommend it.

l have one just like it I got this one for my daughter it works great

handy item to check for battery status.
recommended

Extra fast delivery. Great product (non-rechargeable batteriesonly).
This battery tester measures the battery voltage under load.
150mA (AA,C,D), 50mA (AAA, NiCad, large button cell), 1mA (small button cell)and 10mA (all others).
Be sure to test 3/4in button cells only under the red button (50mA drain)
Testing them with the test leads applies only 1mA drain.
(For rechargeable AAA,AA and 9V batteries, yoiu need a tester that measures mAhr).

Great delivery and product. Recommended.

I've owned this battery tester before. It lasted a very long time until one of the wires broke free at the end. So I bought a new one. It's a little more expensive than some other models but like I said it lasted a long time. 10-20 years probably. It's easy to use %26 read and tests all sizes of batteries.

Excellent product

too small

I did not like that the point it was not aiming at zero
