The GBC 39.0100.02 is a compact, self-contained battery tester for checking the charge status of the most common battery formats. It requires no power of its own — it draws the necessary test current directly from the battery being measured.

Made from black plastic, it measures 40×20×40mm and weighs 50g, making it easy to carry in a tool bag or workshop drawer. It covers Alkaline, NiCd, and NiMh chemistries across AA, AAA, C, and D formats, as well as 9V and button cell batteries.
