Frequently asked questions
Can it test 18650 rechargeable cells?
18650 cells are not among the battery types listed. Use a voltmeter or the display of a suitable Li-ion charger to check those cells.
How do I read the bar graph?
The bar graph shows an approximate remaining charge. Use the coloured zones as a guide to judge whether a battery still has useful capacity or should be replaced.
