Can coin cell batteries withstand high and low temperatures?

The maximum permissible temperatures for a battery are -55° and +125° Celsius. However, the best working environment for most cells is one where temperatures are between +10° and +35° Celsius.

What is the specific feature of alkaline coin cells?

They can deliver high currents as the initial voltage level is 1.5 Volts. However, after a while, the voltage drops relatively fast. That is why these batteries are less suitable and reliable for cameras and measuring equipment.

Why do lithium coin cells last so long?

Lithium batteries last a very long - up to ten years - even when they are hardly used at all. The self-discharge per year is only 1% of the capacity.

Why is there always silver oxide in the batteries for watches?

The voltage of this system is high and remains constant for quite a long time. The time must always be reliable.

What kind of coin cell batteries are there?

There are several systems. The properties are tailored to the most important applications.

Silver oxide (watches, cameras): High constant voltage, self-discharge less than 5% per year.

Alkaline (electrical appliances): Supplies large currents, voltage drops during use, self-discharge less than 3% per year.

Lithium (cameras and electronic devices): Self-discharge less than 1% per year, not suitable for heavy loads.

Zinc air (hearing aids): High capacity, self-discharge 3% per year (if not activated).

Mercury oxide (electrical appliances, hearing aids and cameras): Supplies large currents, self-discharge 2% per year, environmentally unfriendly 15% mercury.

Mercury-containing batteries have not been manufactured since 1998 and have not been supplied by factories since 1999. A replacement zinc air battery is available for a small number of these batteries.

What is a coin cell battery used for?

There are many applications. The most important are watches, cameras and hearing aids. In addition, calculators, games and car alarms are major consumers.

What is a coin cell or button battery?

A button cell is a round battery whose diameter is usually greater than its height. Sometimes they are extremely small and then they look like a button or a coin. That is why they are also called button cells.

What does disposal fee mean?

For all products that contain a battery (or are loose), a disposal fee must be paid to Stibat. This is in line with international laws and regulations (environment). This also applies to devices that are supplied with batteries (e.g. torches).
Commercially used batteries can be collected by a licensed collection company. Commercially used batteries can be collected by a licensed collection company.

What is the Stibat?

Stibat stands for Batteries Foundation. This is the organisation that coordinates the collection activities for empty batteries in the Netherlands. They develop activities in various areas to inform everyone about the how and why of the collection of used batteries. And this is done on a non-profit basis. Since 1995 there has been a legal regulation stating that used batteries must be collected and recycled by or on behalf of producers and importers of batteries. Stibat has taken over this task. A so-called disposal fee must be paid per battery. Elfa is a member of Stibat and charges you the relevant disposal contribution for each battery.

 

Stibat arranges the collection of batteries. Empty batteries do not belong in the bin. It may contain substances that are harmful to the environment, such as the heavy metals mercury, lead and cadmium. They harm the environment when disposed in the household waste. That’s why it is a good thing that more people return empty batteries. Separate from other waste. Not only the well-known penlite batteries can be returned, but also coin cells and the batteries in, for example, mobile telephones, photo and film cameras and cordless tools. Rechargeable batteries may last longer than single-use batteries, but at some point they also cease to function properly and must be disposed of responsibly. Handing in empty batteries separately not only saves the environment, but the metals of the battery are recycled for reuse (think nickel, steel and zinc). New products are made from this, such as zinc gutters, crash barriers, but also new batteries. From 25 million kilos of recycled batteries, 13 million kilos of usable metals were recovered over a period of 12 years! That is a significant saving on our mineral resources.

What is NEN?

NEN stands for National Standardisation Institute. Those who participate in standardization share their knowledge in order to benefit from it together with others. Standardisation strives for efficient, safe, healthy and sustainable products and processes. Several interests are united in a smart way. NEN is the national standardization institute in the Netherlands. They work on economic growth and well-being in a European (CEN, CENELEC and ETSI) and worldwide (ISO, IEC and ITU) context. As the Dutch centre of standardization, NEN helps companies and other organisations to make clear and applicable agreements with each other.
