IEC 60086-2-2:20 26适用于基于标准化锂（非水）电化学系统的原电池。 它规定: -物理尺寸， ——放电试验条件和放电性能要求。 本第一版取消并取代了2021年发布的IEC 60086-2第十四版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)将具有水性电解质的电池分离成单独的部分2-1:物理和电气规范； b)FR10G445和FR14505的最大开路电压从1.83 V变更为1.90 V； c)FR10G445的数字音频测试负载从50mA更改为75mA，并修改MAD； d)FR10G445增加便携式照明测试；e)FR14505增加了电机/玩具和收音机/时钟/遥控器测试； f)在第3条中，术语根据其功能重新排序:电化学系统、电化学系统、电气特性和规格； g)将IEC 60086 2:20 21通用名称的附件D移至IEC 60086 1:20 26，作为附件H； h)删除了IEC 60086 2:20 21合规性检查表的附录E，并将其合并到IEC 60086 1:20 26的附录J中。

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.
