Alkaline batteries, lithium batteries and specialist batteries such as Air-alkaline and ZincAir-alkaline. Alkaline batteries are often affordable and ideal for applications where power consumption is usually low. Lithium batteries last up to 7 times longer and can offer a higher peak power. More information about the different types of non-rechargeable batteries (primary batteries) can be found here.
RoHS stands for Restriction of the use of certain Hazardous Substances. The European RoHS directive came into force in February 2003. It concerns the use of lead, cadmium, mercury, hexavalent chromium, PBB and PBDE. Lead-free soldering is an important part of this guideline. For the complete EU directive, click here.
No, normal alkaline batteries can’t be recharged. However, there are rechargeable alkaline batteries, but these have several big disadvantages:
NEN stands for the National Standardization Institute. Those who participate in standardization share their knowledge to benefit from it together with others. Standardization 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 in European (CEN, CENELEC and ETSI) and worldwide (ISO, IEC and ITU) related to economic growth and well-being. As the Dutch center of standardization, NEN helps companies and other parties to make clear and applicable agreements with each other.

A distinctive system within the different types of primary batteries is air-alkaline. This battery type uses oxygen (O2) from the air as the cathode. In an electrical system with two poles or electrodes we speak of cathode for the pole where the electrons go in. The oxygen is fed to the cathode through the small holes in the housing of the battery, where reduction (absorption electrons) occurs on a carbon layer. In the battery housing only an anode has to be enclosed. This will result in an energy density per weight between 220 to 300 Wh/kg on average (compared to 99 to 123 Wh/kg of a silver-oxide battery).
An additional advantage of this battery type is the relatively low cost and its environmentally friendly nature. These batteries have an infinite shelf life, until they are exposed to air which will activate them. After activation, the shelf life will become relatively short due to the high self-discharge rate. Another drawback: once activated, the chemical process of energy production is unstoppable; however, it can be slowed down.
Air-alkaline battery applications:
Stibat stands for Stichting Batterijen. This is the Dutch organization that coordinates the collection activities for dead batteries in the Netherlands. They develop activities in various fields to inform everyone about the how and why of the collection of dead batteries. And that happens without a commercial motive. Since 1995, there has been a statutory regulation that requires used batteries to be collected and recycled by or on behalf of manufacturers and importers of batteries. Stibat has taken on this task. A so-called disposal fee must be paid per battery. Elfa is affiliated with Stibat and charges you the relevant disposal fee per battery.
Stibat arranges for batteries to be collected. Dead batteries do not belong in the trash can. It may contain substances that are harmful to the environment, such as the heavy metals mercury, lead and cadmium. These harm the environment when disposed of with household waste. That is why it is good that more and more people are handing in dead batteries separately. Separated from other waste. Not only the well-known penlite batteries can be returned, but also button cells and the batteries in, for example, mobile telephones, photo and film cameras and cordless tools. Rechargeable batteries do last longer than single-use batteries; at some point, however, they no longer function properly and must also be disposed of in a responsible manner. By disposing of dead batteries separately, not only is the environment saved, but the reusable metals of the battery are recycled for reuse (think of nickel, steel and zinc). New products are made from this, such as zinc gutters, crash barriers, but also new batteries. As a result, 13 million kilos of usable metals have been recovered from 25 million kilos of recycled batteries over a period of twelve years! That is a considerable saving on our mineral resources.

You can compare the operational features of a rechargeable battery to that of a car battery. If it becomes empty, it can be recharged and reused again. With optimal treatment, these batteries can be recharged up to a few thousand times. Due to the constant voltage rate (1,2 Volt) the rechargeable battery will provide a stable power source from the beginning to the end. Rechargeable batteries suddenly die and from that moment on will not work anymore unless they are recharged again.
Rechargeable batteries have a long shelf life and can be recharged up to a thousand times. They are more expensive to purchase compared to non-rechargeable alkaline and zinc carbon batteries, but if you use batteries on a regular chase non-rechargeable batteries any more. Furthermore, rechargeable batteries reduce the amount of waste which will have a positive contribution to the environment.
Because rechargebale batteries last longer, less Alkaline batteries will end-up in the trash. Ask us if your applications is suited to use with rechargebale batteries.
Below you can find the standard abbreviations for the various battery systems. These are the universal terms that also can be found in the product catalogue. The table makes a distinction between round (R) and flat (F) batteries. The P stands for all batteries that are not round.
|B = Lithium carbon monofluoride (low drain)||BR|
|C = Lithium mangaan dioxide (high drain)||CR|
|E = Lithium thionyl chloride||ER|
|F = Lithium iron disulfide||FR|
|G = Lithium Copper oxide||GR|
|K = Cadmium||KR|
|L = Alkaline||LR|
|M = Mercury||MR|
|P = Oxygen||PR|
|S = Silver||SR|
LR batteries are thus round alkaline batteries and flat alkaline batteries would thus be LF batteries.
Yes. However, alkaline batteries have a voltage of 1,5 in the beginning, but this quickly drops after a period of time (even below the level of a rechargeable battery). In contrast rechargeable batteries have a very stable voltage variation over the used period of time.
The maximum allowable temperature for button batteries is between -10°C and +65°C. However, the best working environment is between +10°C and +35°C.
There are several types of rechargeable button batteries. These batteries are often built into the devices. However, in consumer stores they are rarely available, partly due to the low demand.
The negative pole is at the top and the positive pole is at the wider bottom of the battery. The plus pole usually provides information about brand and the model number of the battery. This side of the battery is almost always on top when inserting into a device.
The different types of hearing aid batteries are identified by the sticker on the battery pack. These batteries are packed in a blister of 6 pieces.
Battery - Colour - Application
5 - Red - Mini hearing aids in the ear canal
10 - Yellow - Mini hearing aids in the ear canal
13 - Orange - Hearing aids behind the ear and in the ear shell
312 - Brown - Hearing aids in the ear canal
675 - Blue - Hearing aids behind the ear
This depends on the type and the intensity of use. In general, the larger batteries of the type 675 last up to three weeks, while the smaller batteries (5 and 10) only last for a few days.
LED stands for Light Emitting Diode, and is seen as the lighting system of the future.
This type of lighting can be seen as the successor to incandescents. Incandescents have the disadvantage that the filament burns out after a certain period of time. For LEDs this is not the case.
LED LIGHTS don’t use filaments but convert electricity directly into lighting. This ensures much less power is needed in order to create lighting. One other advantage is the much longer lifespan of LED lights.
The advantages of LED in a glance:
The disadvantages of LED in a glance (especially with older LEDs):
The main factors for this are: the electrochemistry of the battery, the ambient temperature and the energy consumption of the application.

There is a large variety of fittings available that can be applied to different types of lamps. Below you can find the most common ones:
A light bulb consists of a vacuumed or with glass-filled glass bulb with a filament. When power flows through the filament, this will glow and emit light. There are various bulb types for different applications. Which bulb type will be used depends on the kind of gas is added to it. In general, we speak of three types of bulbs: the ‘normal’ (krypton) bulb, halogen bulb and xenon bulb.
ATEX stands for ATmosphères EXplosives. If a lamp is ATEX certified the lamp will be suitable for use in a hazardous environment. Whether a lamp is or is not ATEX certified can be seen on the housing of the lamp, because this is engraved in the product. Elfa has a number of leading brands which are ATEX certified in its product range. Look here for more information.
Whether a lamp is or is not ATEX certified can be seen on the housing of the lamp. This consists of a number of encodings. These codes and what they stand for can be defined as the following:
An ATEX certification must be issued by a notified body, such as KEMA or DEMKO. If the lamp is assessed by a non-certified testing institute the zone in which the certification is granted will be a maximum of 2. This is the lowest protection class/zone. Fore more information on ATEX look here.
ATEX stands for ATmosphères EXplosives.
An explosive atmosphere is defined as following: a mixture of flammable substances in the form of gases, vapour, mists or dust under atmospheric conditions, in which the combustion will spread to the entire mixture after ignition.
Since July 2003 ATEX 95 and ATEX 137 are introduced. These guidelines are written specifically to focus on safety in explosive environments and to set legal obligations to the use of explosive-proof products in these hazardous environments.
The directive applies to all companies where “the use of flammable substances can create a dangerous explosive atmosphere and lead to an explosion hazard”. For more information about ATEX look here.
ATEX talks about danger zones.
The atmosphere and the prevailing condition in the workplace are crucial for installation methods of the used materials and the choice of equipment. Therefore, it is important to make a zone classification of areas that might be dangerous (for the purpose of gas- and explosion hazard).
These potential dangerous areas are based on the frequency and the duration of an explosive atmosphere:
The lowest number indicates the most dangerous zone. As the danger zone becomes heavier, the stricter the demands become on the design of the work environment, the application, the use of equipment and security systems. look here.
There are several differences between lithium and alkaline batteries. Below are the most important ones:

Nickel cadmium batteries and nickel metal hydride batteries have some interesting differences from each other:
Nickel metal hydride batteries have up to twice the capacity of nickel cadmium batteries.
Nickel cadmium batteries often suffer more from the "memory effect" than nickel metal hydride batteries.
Nickel metal hydride batteries require less maintenance and care.
The nickel metal hydride battery can be considered as the development on the nickel cadmium battery. For more information, click here.
Alkaline batteries are the most used types of batteries. An alkaline battery supplies a lot of energy, even at lower temperatures. These batteries are suited for one-off use, have the lowest purchase price and low self-discharge. They are highly suited for devices that use little current for long periods of time. Click here for more information on alkaline batteries and different types of batteries.
The most commonly used accumulator is the lead-acid battery. This is due to the simple construction of the battery and a generally low price. For more information on this battery type, as well as a recommendation from a brand offering interesting lead batteries, please click here.
Yes. The higher the capacity, the longer the battery will last. The capacity is expressed in Ampère hour (Ah) or milli-Ampère hour (mAh). In most cases, you can read on the battery itself and on the packaging how high the capacity of a battery is. So for the application equipment more capacity will allow a longer useful life. It is therefore not harmful to use bigger batteries but it is harmful to use other voltages than indicated.
These are a certain type of batteries that have a number of distinguishing points:
Lithium batteries are characterized by a very low self-discharge. The self-discharge is only 1% of the capacity per year. The voltage with this battery is exceptionally high. This information sheet lists a number of brands that produce lithium batteries, as well as the different product variants that go with them. Lithium is a light metal with an exceptionally high capacity (3.86 Ah / gram). Mixing lithium with other chemicals such as manganese or sulfur results in a battery with high energy, low weight, reduced self-discharge and the ability to perform under extreme conditions.
Applications of lithium batteries
Lithium is used for many applications; from mobile phones and microprocessors to large industrial work situations such as in the oil and gas industry and space travel.

Formats have a name and can also have a code. The names are more or less the same in all countries, though other terms may be used popularly. The codes are different everywhere, e.g. the international IEC code and the American code. Also, each brands often uses its own codes. This often makes it difficult to recognise the codes on packaging. Still, the IEC code is the most common. In the IEC code, the battery types can be recognised by the letters. For instance, Alkaline is called LR, zinc carbon batteries have an R as first letter.
