C / R14 batteries

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.

Batteries R14 in the range of Botland

In our assortment you will find high-quality batteries LR14 R14 and leading manufacturers such as Panasonic, Varta or Energizer. Batteries LR14 Varta Industrial has been adapted to work in difficult environmental conditions can be used safely in temperature range from -10 oC to +50 oC. Great links LR14 Duracell to provide long life (about 10 years), thanks to the patented technology and Duralock are available in sets of 2 PCs. For less demanding devices with low current consumption (e.g., for flashlights with smaller capacity) recommended battery R14 Panasonic Red Bat, also available in kits of two pieces.
