Being lithium batteries means they keep close zu 1.5V until they are almost empty. It aussehen like this battery has actually some sort von over present protection.

Discharging weist low current (10mA) shows the higher voltage (1.7V) from this batteries, however there is no extra capacity to be gained.

ConclusionThese battery are die best primary batteries around, but so rather expensive und some devices may schutz problems with ns high voltage.Notes and linksHow is the prüfen done and how kommen sie read die chartsCompare to other AA/AAA batteries: Alkaline/NiMH/Lithium
