Primary batteries - Part 2-2: Physical and electrical specifications of lithium batteries EN IEC 60086-2-2:2026

Publication date:   Aug 5, 2026

Scope

IEC 60086-2-2:2026 is applicable to primary batteries which are based on standardised lithium (non-aqueous) electrochemical systems.

It specifies:

- the physical dimensions,

- the discharge test conditions and discharge performance requirements.

This first edition cancels and replaces the fourteenth edition of IEC 60086-2 published in 2021. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) separation of batteries with aqueous electrolyte into a separate Part 2-1: Physical and electrical specifications;

b) maximum open circuit voltage of FR10G445 and FR14505 was changed from 1,83 to 1,90 V;

c) load of digital audio test for FR10G445 was changed from 50 mA to 75 mA and MAD was modified;

d) portable lighting test was added for FR10G445;

e) motor/toy and radio /clock /remote control test was added for FR14505;

f) in Clause 3, terms were reordered according their functions: electrochemical systems, electrochemical systems, electrical characteristics and specifications;

g) Annex D for common designation of IEC 60086 2:2021 was moved to IEC 60086 1:2026, as Annex H;

h) Annex E for Compliance checklist of IEC 60086 2:2021 was removed and merged into Annex J of IEC 60086 1:2026.
