Lithium-ion batteries represent the most advanced re-chargeable battery technology in general use today and are found in handheld electronical equipment like mobile phones, cameras, portable PCs, as well as all modern B&K Sound Level Meters and other measuring equipment.
The energy density of Li-ion batteries exceeds that of traditional rechargeable battery technologies – this requires some attention during transport, use and waste-handling.
All Li-ion Battery Packs supplied by B&K are classified as UN 3480/UN 3481, and
- Comply with applicable transportation regulations including
-IATA "Dangerous Goods Regulation" (International Air Transport Association)
-ICAO "Technical Instructions..." (International Civil Aviation Organisation)
-CAAC "Transport regulations for Lithium batteries" (Civil Aviation Administration of China)
-IMDG Code (International Maritime Dangerous Goods), and
-IEC 62281 "Safety of primary and secondary lithium cells and batteries during transport"
Have been tested according to the UN "Regulation on the Transport of Dangerous Goods" Sec. 38.3
Have a rated capacity of less than 100 Wh corresponding to an equivalent Lithium content of less than 8 g - i.e. need not to be handled as Dangerous Goods
When travelling by air Li-ion spare batteries must be in carry-on luggage - they are not allowed as checked-in luggage. Batteries installed in equipment are not covered by this restriction.
Before shipping a Li-ion battery, either as spare battery or as part of an instrument, make sure that it isn't damaged in any way.
Charging B&K supplied Li-ion batteries must only be done by inserting it into the original product, or charging it with a dedicated B&K Li-ion charger.
Instruments with batteries being charged will become warm, especially when constantly charged and/or being inside a suitcase or the like. A temperature sensor will automatically shut down charging before it becomes too warm.
||The ageing of Li-ion batteries is influenced by three main factors:
- the time since the cells were manufactured,
- the temperature of the battery above 0°C, and
- the number of times it has been charged.
Li-ion batteries will typically last for 2-4 years or up to 1000 charge/discharge cycles depending on the conditions of use and storage (e.g. storage at 25°C will permanently reduce the capacity by 20% per year).
When the battery is no longer able to hold a useful amount of charge, it is time to exchange the battery with a new one.
Avoid any contact with the Li-Ion cells inside the Battery Pack - wear gloves and safety glasses if it can not be avoided.
Discarded batteries should be disposed of locally by using the appropriate local return and collection systems.
