BT-168 Battery Tester for AA, AAA, C, D, 9V and Button Cells

Pocket tester for AA, AAA, C, D, 9V and button cells. Slide the adjustable arm against the cell and the indicator shows whether it is good, low or due for replacement — useful for sorting the dry cells that power AA-battery radios, multimeters, remotes and field lights before a flying session.

Key features

• Standard and rechargeable cells: tests ordinary dry cells as well as rechargeables.
• Adjustable sliding arm holds everything from button cells up to D size.
• Colour-coded good / low / replace reading at a glance.
• No internal battery: it runs from the cell under test, so there is nothing inside to go flat.
• Compact and light enough to live in a toolbox or field bag.

Not suitable for LiPo or Li-ion drone packs: check those with a LiPo cell checker on the balance lead or with your charger's per-cell voltage readout.
