from 9 to 8, and the average value of the result calculation is not excluded (see 5.3 of

this Edition; 5.3 of 2013 Edition);

--- Modify the relative humidity conditions of non-P system batteries in Table 3 (see 6.1 of

this Edition; 6.1 of 2013 Edition);

--- Increase the standard discharge voltage of Y chemical system and W chemical system

battery (see Annex G.3 of this Edition);

--- Modify the order of the annex to make it consistent with the order of appearance in the

main text, and added explanatory text at the position where the main text appeared for

the first time;

--- Add Annex D (informative) warning sign (see Annex D of this Edition);

--- Add Annex E (normative) on the packaging and child-resistant disassembly requirements

of coin batteries (see Annex E of this Edition);

---Add Annex F (informative) the use of the warning sign "keep away from children" (see

Annex F of this Edition).

This Part uses redrafting method to modify and adopt IEC 60086-1.2015 Primary Batteries -

Part 1.General.

The technical differences and the causes between this Part and IEC 60086-1.2015 are as follows.

--- Regarding normative references, this Part has made adjustments with technical

differences to adapt to the technical conditions of China. The adjustments are

concentrated in Clause 2 "Normative References". The specific adjustments are as

follows.

 Use GB/T 8897.2-2021 that modifies and adopts the international standard to

replace IEC 60086-2.2015;

 Use GB/T 8897.3-2021 that modifies and adopts the international standard to

replace IEC 66086-3.2016;

 Delete IEC 60086-4.2014 and IEC 60086-5.2016.

--- Add the definition of explosion (see 3.23 of this Edition).

--- Modify the maximum open-circuit voltage in the F-system battery from 1.83V to 1.90V

(see 4.1.4 of this Edition).

--- Modify the marking requirements, so as to meet the requirements of China's relevant

regulations and standards (see 4.1.6 of this Edition).

--- Modify the requirements for the battery listed in the national standard, so as to comply

with the actual conditions of China [see c) and d) of Annex A of this Edition].

--- Add Annex D (informative) warning sign (see Annex D of this Edition);

--- Add Annex E (normative) on the packaging and child-resistant disassembly requirements

of coin batteries (see Annex E of this Edition);

---Add Annex F (informative) the use of the warning sign "keep away from children" (see

Annex F of this Edition).

This Part was proposed by China National Light Industry Council.

This Part shall be under the jurisdiction of National Technical Committee on Primary Battery

of Standardization Administration of China (SAC/TC 176).

Primary Batteries - Part 1.General

1 Scope

This Part of GB/T 8897 is intended to standardize primary batteries with respect to

electrochemical system, dimensions, nomenclature, terminal configurations, markings, test

methods, performance, reliability and environmental aspects. As a primary battery

classification tool, electrochemical systems are also standardized with respect to system letter,

electrodes, electrolyte, nominal and maximum open-circuit voltage.

2 Normative References

The following documents are essential to the application of this document. For the dated

documents, only the versions with the dates indicated are applicable to this document; for the

undated documents, only the latest version (including all the amendments) is applicable to this

document.

3 Terms and Definitions

For the purposes of this document, the following terms and definitions apply.

A source of electric energy that is obtained by direct conversion from chemical energy.

4 Requirements

This type of terminal is used for batteries which have their dimensions specified according to

Figures 1 to 4 and Figure 6 of GB/T 8897.2-2021 and which have the cylindrical side of the

battery insulated from the terminals.

5 Performance - Testing

For application test with multiple loads, the load order during a cycle shall start with the

heaviest load and move to the lightest load unless otherwise specified.

When full capacity is not realized within the required time scale, the service output may be

extended to the shortest suitable duration thereafter by selecting a discharge load of higher

ohmic value, as defined in 6.4.

6 Performance - Test Conditions

The value of the resistive load (which includes all parts of the external circuit) shall be as

specified in the relevant specification sheet and shall be accurate to +/- 0.5 %.

The accuracy of the measuring equipment shall be no less than 0.25 % and the precision shall

be no less than 50 % of the value of the last significant digit.

7 Sampling and Quality Assurance

The use of sampling plans or product quality indices should be agreed between the

manufacturer and the purchaser. Where no agreement is specified, refer to GB/T 2828.1 and

ISO 22514-2 for sampling and quality compliance assessment advice.

8 Battery Packaging

A code of practice for battery packaging, shipment, storage, use and disposal can be found in

Annex J.

Annex A

(Normative)

Criteria for the Standardization of Batteries

Batteries and electrochemical systems shall meet the following requirements to justify their

initial inclusion or ongoing retention in the GB/T 8897 series.

Annex B

(Normative)

Recommendations for Equipment Design

It is recommended that companies producing battery-powered equipment maintain close liaison

with the battery industry.
