Cell and Battery

As we know that Primary battery is portable voltaic cell is not rechargeable and Secondary battery is the rechargeable battery that needs specific using and disposal. By the scope of TIS standard specifies requirements, tests and marking for portable sealed secondary cells and batteries and the below standards are major to use for references.

TIS 2218-2548(2005) Secondary cells and batteries containing alkaline or other non-acid electrolytes

– Secondary lithium cells and batteries for portable applications

IEC 61438 Possible safety and health hazards in the use of alkaline secondary cells and batteries

– Guide to equipment manufacturers and users

IEC 61951-1 Secondary cells and batteries containing alkaline or other non-acid electrolytes

– Portable sealed rechargeable single cells – Part 1: Nickel-cadmium

IEC 61951-2 Secondary cells and batteries containing alkaline or other non-acid electrolytes

– Portable sealed rechargeable single cells – Part 2: Nickel-metal hydride

ISO/IEC Guide 51 Safety aspects – Guidelines for their inclusion in standards


What difference do the cell and battery make?

While the secondary cell is a basic manufactured unit that providing a source of electrical energy by direct conversion of chemical energy that consists of electrodes, separators, electrolyte, container and terminals, and that is designed to be charged electrically, the secondary battery is assembly of secondary cell(s) ready for use as source of electrical energy characterized by its voltage, size, terminal arrangement, capacity and rate capability. And the portable cell is a cell intended for assembly in a portable battery, the portable battery is a battery for use in a device or appliance which is conveniently hand carried. They are mandatory to get TIS 2218-2548(2005) mark by TISI approval


The Marking

Cell and Battery have to be marked as specified following applicable standards IEC 61951-1, IEC 61951-2 or TIS 2218. Except for cells which manufacturer and user has agreement, then cells used in the manufacture of battery need not be marked. And the specified information that required to be marked on battery or supplied with battery as a user manual are ‘Disposal instructions’ and ‘Recommended charging instructions’. This conformity will be checked by examination of marking and documentation of manufacturer.
