IEC 61960-2003 pdf – Secondary cells and batteries containing alkaline or other non-acid electrolytes – Secondary lithium cells and batteries for portable applications.
1 Scope This International Standard specifies performance tests, designations, markings, dimensions and other requirements for secondary lithium single cells and batteries for portable applications. The objective of this standard is to provide the purchasers and users of secondary lithium cells and batteries with a set of criteria with which they can judge the performance of secondary lithium cells and batteries offered by various manufacturers. This standard defines a minimum required level of performance and a standardized methodology by which testing is performed and the results of this testing reported to the user. Hence, users will be able to establish the viability of commercially available cells and batteries via the declared specification and thus be able to select the cell or battery best suited for their intended application. This standard covers secondary lithium cells and batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which it releases its electrical capacity, a characteristic nominal voltage and a characteristic end-of-discharge voltage during discharge. Users of secondary lithium cells and batteries are requested to consult the manufacturer for advice. 2 Normative references The following referenced documents are indispensable for the application of this document.

3 Terms and definitions For the purpose of this International Standard, the definitions contained in IEC 60050-486 and the following apply. 3.1 charge (capacity) recovery capacity that a cell or battery can deliver after the charge following the charge retention test according to 3.2 3.2 charge (capacity) retention capacity that a cell or battery can deliver after storage, at a specific temperature, for a specific time without subsequent recharging as a percentage of the rated capacity 3.3 final voltage end-of-discharge voltage specified closed circuit voltage at which a discharge of a cell or battery is terminated 3.4 nominal voltage: suitable approximate value of voltage used to identify the voltage of a cell or battery NOTE 1 The nominal voltages of secondary lithium cells are given in Table 1. NOTE 2 The nominal voltage of a battery of n series connected cells is equal to n times the nominal voltage of a single cell. 3.5 rated capacity quantity of electricity C 5 Ah (ampere-hours) declared by the manufacturer which a single cell or battery can deliver during a 5-h period, when charged, stored and discharged under the conditions specified in 7.2.1 3.6 secondary lithium battery unit which incorporates one or more secondary lithium cells and which is ready for use. It incorporates adequate housing and a terminal arrangement and may have electronic control devices 3.7 secondary lithium cell secondary single cell whose electrical energy is derived from the oxidation and the reduction of lithium. It is not ready for use in an application because it is not yet fitted with its final housing, terminal arrangement and electronic control device
