GB/T 48038-2026Lithium primary batteries for wide temperature range (English PDF)

Foreword

This document was issued on 30 July 2026 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 August 2027.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies.

It is classified under ICS 29.220.10 and Chinese classification K 82.

The document runs to 15 pages. The identification, the dates, the classification and the table of contents on this page are taken from the cover and the printed contents of the standard itself.

This document was drafted in accordance with GB/T 1.1-2020 "Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents".

Attention is drawn to the possibility that some elements of this document may be the subject of patent rights. The issuing body assumes no responsibility for identifying them.

This document was proposed by the China National Light Industry Council.

It is under the jurisdiction of the National Technical Committee on Primary Batteries of Standardization Administration of China (SAC/TC 176).

The drafting organisations include Yichang Lijia Technology, Songbai (Guangdong) Battery Industry, Huizhou EVE Energy, Changzhou Liba Battery, Nanping Nanfu Battery, Wuhan Fanso Technology, Changzhou Yufeng Battery, the Research Institute of Chemical Power Sources of the Light Industry, Zhengzhou University of Light Industry, Wuhan Haocheng Lithium Battery Technology and a further group of cell and materials makers.

1 Scope

GB/T 48038 covers lithium primary batteries built to work across a wide temperature range, the non-rechargeable cells expected to deliver at forty below and at sixty above. That span is the whole point: an ordinary cell loses most of its capacity in the cold and vents or swells in the heat, and the applications that need this behaviour are the ones nobody can service easily - utility meters, oilfield instrumentation, remote sensors. The document covers the type designation system, the appearance and performance requirements, the safety requirements for intended use and for foreseeable misuse, the test methods, the inspection rules, and marking, packaging, transport, storage and disposal. An informative annex lists the common types and what each has to deliver. For a manufacturer or a purchaser, this is the specification a Chinese supply contract cites.
