GB/T 8897.3-2021Primary batteries - Part 3: Watch batteries (English PDF)

Foreword

GB/T 8897 "Primary Battery" is divided into 5 parts.

---Part 1.General Provisions;

---Part 2.Dimensions and electrical properties;

---Part 3.Watch battery;

---Part 4.The safety of lithium batteries;

---Part 5.Safety requirements for aqueous electrolyte batteries.

This part is Part 3 of GB/T 8897.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 8897.3-2013 "Primary Battery Part 3.Watch Battery", which is mainly compared with GB/T 8897.3-2013

The technical changes are as follows.

---Revised the battery sizes in Table 1 and Table 2 (see Table 1, Table 2, and Table 1 and Table 2 of the.2013 edition);

---The relative humidity of 7.2.1 has been revised (see 7.2.1, 7.2.1 of the.2013 edition);

---Revised the resistance and time tolerance of Table 6 (see Table 6, Table 6 of the.2013 edition);

---Revised the resistance and time tolerance of Table 7 (see Table 7, Table 7 of the.2013 edition);

---Revised the discharge resistance value of some batteries in Table 8 (see Table 8, Table 8 in the.2013 edition);

---The relative humidity of 8.1 has been revised (see 8.1, 8.1 in the.2013 edition).

This section uses the redrafting law to modify and adopt IEC 60086-3.2016 "Primary Battery Part 3.Watch Battery".

Compared with IEC 60086-3.2016, this part has structural changes and appendix B has been added.

The technical differences between this part and IEC 60086-3.2016 and the reasons are as follows.

---Regarding normative reference documents, this section has made adjustments with technical differences to adapt to my country's technical conditions and adjustments.

The situation is collectively reflected in Chapter 2 "Normative Reference Documents", and the specific adjustments are as follows.

* Replace IEC 60086-1.2015 with GB/T 8897.1-2021 modified to adopt international standards;

* Replace IEC 60086-2.2015 with GB/T 8897.2-2021 which is modified to adopt international standards;

* Added reference to GB/T 2828.1.

---Modified the marking requirements to meet the requirements of relevant Chinese technical regulations and standards [see 4.8.1e) and 4.8.1f)];

---The normative Appendix B "Inspection Rules" has been added.

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

This part is under the jurisdiction of the National Primary Battery Standardization Technical Committee (SAC/TC176).

3 Terms and definitions

The following terms and definitions defined in GB/T 8897.1-2021 apply to this document.

3.1

Capacitivereactance

A component of internal resistance that causes a voltage drop during the first few seconds of applying a load.

3.2

Capacitive

The charge (power) that the battery can output under specified discharge conditions.

Note. The unit of charge is coulomb (1C=1A.s), and the capacity is usually expressed in ampere-hour (A.h).

3.3

New battery freshbattery

Produce undischarged batteries that are less than 60 days old.

3.4

Ohmicdrop

The voltage drop caused by a component of the internal resistance at the moment the load is applied.

4 Dimensions and physical performance requirements

41 January.2014; 4Y. November.2014.

c) The polarity of the positive extreme ().

d) Nominal voltage.

e) The name, trademark and address of the manufacturer or supplier.

f) Implementation standard number.

g) Mercury content (where applicable).

h) Precautions for safe use.

i) For warnings to prevent accidental swallowing of batteries, see 4.1.6.2c) of GB/T 8897.1-2021.

Note 1.The battery logo must not hinder electrical contact.

Note 2.The battery model is marked according to the naming in Appendix A. If you need to add the standard battery common name, please refer to Appendix E in GB/T 8897.2-2021.

Note 3.When the mercury content of the button battery is not more than 0.005mg/g, it is marked as "No mercury".

6 Sampling and quality assurance

The sampling plan or product quality index used should be negotiated between the supplier and the buyer. When there is no agreement between the two parties, GB/T 2828.1 or

ISO 22514-2.2017 should be adopted.

If the supplier and the demander agree, the plan in Appendix B should be adopted.
