EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62485-4 testing. IEC EN 62485-4 applies to safety considerations regarding accommodation, circuit arrangements, and operation of secondary valve regulated lead-acid cells and batteries in portable devices.
Requirements are laid down that oblige manufacturers of instruments and secondary batteries to prevent misuse of batteries during operation in order to provide protective measures to prevent injury to persons in the event of a battery failure and to provide users with adequate information. This standard does not apply to secondary cells and batteries containing alkaline or other non-acid electrolytes.
This standard provides information on the safety and health protection of persons when using valve regulated lead-acid batteries used as DC power supply systems in portable devices. The standard therefore applies to valve-regulated lead-acid batteries and battery systems available on the market.
IEC EN 62133 has preference for secondary cells and batteries containing alkaline or other non-acid electrolytes. It is possible to use both primary and secondary batteries or batteries in some portable devices or toys. Where these batteries or batteries are interchangeable, the standards for primary batteries of the IEC EN 60086 series, Parts 1 to 5, are preferred.
The charging instructions applicable to batteries and chargers must be followed. Where batteries are intended to be replaced by the end user, the equipment manufacturer will provide clear instructions on the battery being replaced.
Battery systems for portable devices should not overheat. Overheating from service conditions will also destroy the battery and in some cases equipment. Corrosive or toxic liquids or gases may be released. Therefore, batteries must be placed in devices not exceeding the allowable temperature range declared by the manufacturer.
Batteries will be protected from mechanical damage that can cause leakage of dangerous chemicals causing overheating and then short circuits that can cause breakdown of other cells.
Terminals shall be designed to minimize voltage drop and associated heat generation. The terminals inside the battery compartments shall consist of material resistant to corrosion from the battery electrolyte.
