IEC 60086-2-1:2026 is applicable to primary batteries which are based on standardised electrochemical systems using aqueous electrolytes.
It specifies:
- the physical dimensions,
- the discharge test conditions and discharge performance requirements.
IEC 60086-2-1:2026 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 lithium batteries into IEC 60086-2-2: Physical and electrical specifications;
b) in Clause 3, terms were reordered according to their functions: electrochemical systems, electrical characteristics and specifications;
c) TR03 and TR6 were added in Category 1, Round batteries;
d) load of digital audio test for LR03, TR03 and R03 was changed from 50 mA to 75 mA and MAD was modified;
e) personal grooming test of LR6 was added instead of high drain application test;
f) high drain application test was added for TR6;
g) radio /clock /remote control test was added for R6S;
h) CD, digital audio, wireless gaming and accessories test was removed for LR6, R6P and R6S;
i) 4,5 V of common designation was added for 3LR12, 3R12P and 3R12S;
j) Annex D for common designation of IEC 60086-2:2021 was moved to IEC 60086-1:2026, as Annex H;
k) Annex E for Compliance checklist of IEC 60086-2:2021 was removed and merged into Annex J of IEC 60086-1:2026.
