Batteries C (R14)

Despite the huge popularity of all kinds of batteries, including, of course, are most often used at present, lithium-ion and lithium-polymer, classic, battery remain efficient and easy to use power source for mobile devices. The dimensions of most of these one-time sources of electricity remain unchanged for several decades. In addition to the most common batteries such as "Tom thumb" (denoted (L)R6 or AA) and the "little sticks", i.e., (L)R03 or AAA, still willing to use larger elements R14, R20 and even. If the battery is clearly seen as inexorable are the laws of physics – the smaller the volume of the chain, the less energy can accumulate. The choice of the number and size of the battery for the newly designed device is always associated with the need to reach a compromise between size and weight of the device, and the energy consumption and the expected operating time. If the amount of space in the case allows, is to take the battery R14 to form a robust source of energy for devices with high current consumption.

Types of batteries R14 (and not only)

A widely used General purpose batteries are generally in two variants. Classic cheap links of salt (e.g., battery R14), contain a graphite rod coated with manganese oxide, and in the electrolytic paste containing ammonium chloride and zinc filling the inside of the box. This last is a battery case; at the same time it also serves as a negative electrode of the sensor. Core while connected to the housing cover and forms the positive electrode of the battery. Batteries of this type are characterized by relatively small effect of self-discharge, but offer a relatively small capacity and high internal resistance. This is not suitable for power devices with higher current consumption, but have proven niskomocowych devices (e.g., in a wristwatch with LCD displays or calculators). In turn, the alkaline, for example, LR14, contain an alkaline electrolyte of potassium hydroxide (KOH), which makes that these units acquire much higher capacity and lower internal resistance than their classical counterparts.

Battery parameters

Of course, the best known parameters of the battery are: its type (the size) and voltage. In the case of the discussed battery class (L)R14 the exact dimensions (diameter and length) are approximately the same, regardless of manufacturer and chemical composition (saline, alkaline). The diameter is from 24,9 mm to 26.2 mm, and length 50 mm. Weight, on the contrary, does not exceed, as a rule, values of 70 grams. Rated voltage [v] – as in the case of links cykowo-zinc and alkaline – 1.5 V (although, of course, the new units, is measured without load, show slightly higher voltages). Other important parameters, which often do not find on the packaging are: real capacity and internal resistance and characteristics of the discharge. In the case of alkaline batteries LR14, the nominal capacity is about 8000 mAh (for comparison, the best battery format R6 offer about 2500 mAh). Best LR14 batteries (e.g. Varta Industrial) have measured and described the characteristics of discharge specific to a few examples of the resistance (or current) load.
