Batteries
(789)Batteries can be found in a variety of devices: TV remote controls, watches, wireless PC mice are all equipped with batteries. This is their primary source of energy necessary for proper operation. What is important is that batteries, unlike rechargeable batteries, are non-rechargeable cells. We buy them once and after they are depleted, we dispose of them.
CONSTRUCTION OF BATTERIES – AAA, R6 and others
Batteries can take different shapes and their construction is closely linked to the technology employed. Each battery, regardless of its type, contains two poles – positive (+) and negative (-). Generally speaking, each battery contains three elements: negative electrode, positive electrode and electrolyte. They are made of different materials, depending on the technology, but we can distinguish several basic ones: for the negative electrode these will be zinc and lithium, for the positive electrode – manganese oxide (IV), iron sulphide and silver oxide, while the electrolyte is made of organic substances: zinc chloride or alkaline metal hydroxide.
DIVISION OF BATTERIES BY TECHNOLOGY (LITHIUM BATTERIES, ALKALINE BATTERIES)
-
Alkaline batteries – this type of batteries is characterized by long life (they can maintain energy for up to 7 years) and a wide operating temperature range (from -30°C to +70°C). Additionally, they can be used in devices with medium and high power consumption, such as a shavers or trimmers.
-
Lithium batteries – or, to be precise, lithium-chloride-thionyl batteries can hold energy much longer than alkaline batteries, from 10 to even 20 years. The capacity loss due to self-discharge is around 1% per year. The initial voltage of lithium batteries is 3/3.6V. Batteries of this type are ideal for long-term applications, for example powering memory chips.
Other types of batteries include:
-
Zinc-air batteries – these batteries can be stored in packaging for up to 4 years, but will discharge very quickly. They usually suffice for 3-4 months of use.
-
Zink-carbon batteries – they store energy for up to two years, but may leak!
-
Silver batteries – can be used for up to 5 years, however, after that time they may also leak!
DIVISION OF BATTERIES BY CASE TYPE
Batteries can come in different casings, below you will find some of them:
-
AAA batteries (R3) – classic “triple A” batteries with a nominal voltage of 1.5V; due to their size, they are a very popular source of energy for household appliances.
-
AA batteries (R6) – the so-called “penlites” with a nominal voltage of 1.5V, a larger equivalent of AAA batteries, also very often applied in everyday use devices.
-
9V batteries (6F22) – popular cuboid batteries with a nominal voltage of 9V.
-
Button batteries – thanks to their dimensions, they are very often used in wristwatches. Usually their voltage is 3V.
-
Industrial batteries – in industrial equipment, batteries with specific markings other than classic ones are used, e.g.: 10280 - also known as 2/3 of AA, 14250 – conforming to 1/2 of AA battery size, 14500 – dimensions identical to AA battery, 17500 – same size as type A batteries. It is worth remembering, however, that despite the compatibility of dimensions with standard batteries, industrial batteries very often have different voltage.
-
Batteries with leaded terminals –TME offer also includes batteries with leaded terminals. Leads are terminated with a connector, usually the PHR-2 type, but batteries with non-terminated leads are also available on our offer.
