Gardner Bender GBT-500A Analog Battery Tester

The Gardner Bender GBT-500A is an analog battery tester designed for checking the charge level of common household and specialty cells. It suits technicians, hobbyists, and homeowners who need a quick pass-or-fail indication without a digital multimeter. The unit arrives new and includes integrated test leads for immediate use. It covers a broad range of cylindrical and button-type batteries in a compact handheld form.

14-range analog scale from 1.5 V to 22.5 V

The single specification that decides fit is the 14-range analog scale covering 1.5 V button cells through 22.5 V photo cells, plus standard AA, AAA, 9 V, 12 V, and lantern types. The needle display shows relative charge state across all supported chemistries without requiring battery power for the meter itself. Buyers who need precise voltage readings, digital logging, or the ability to test lithium coin cells below 1.5 V will not find those functions here.

Handheld analog tester with integrated leads

Installation consists of selecting the correct range setting and touching the fixed leads to the battery terminals; no assembly or external power is required. The compact case measures 1.5 by 2.5 by 3.8 inches and weighs .22 pounds, so it fits easily in a tool pouch. Common issues include misreading the scale if the range selector is not matched to the cell under test and intermittent contact on recessed button-cell terminals.

Questions about this item

What does the 14-range scale cover on this tester?

The 14 ranges span 1.5 V button cells through 22.5 V photo cells plus AA, AAA, 9 V, 12 V and lantern batteries.

How does the analog movement limit what you can read?

The needle gives a quick charged-or-replace indication but cannot display exact voltage or internal resistance.

What clearance does the 3.8-inch height need in a toolbox?

At 3.8 inches tall the tester fits in most shallow trays, and the attached leads add only a few extra inches.
