C / R14 batteries

Battery types – R14 and others

Commonly used batteries come in two versions. Most standard zinc carbon cells (also available as an R14 battery version) contain a graphite core inside which is coated with manganese oxide. The core is placed in an electrolytic paste of ammonium chloride and it will tightly fill the inside of the battery, allowing chemical processes to take place, moving electrons, etc. The housing of the R14 battery (and other cells) is not only its outer shell, but plays an important role in the entire process: chemically it is the negative electrode while the core is the positive electrode.

Zinc-carbon cells are cheap and quite inefficient. They are not able to store much energy, but their advantage is that the battery slowly self-discharges.

However, if we are looking for more efficient batteries dedicated to devices with high energy demand, alkaline batteries will be the solution. The alkaline version of R14 batteries are LR14 batteries (according to the IEC number, the worldwide prefix reserved for alkaline batteries is "L-"). These types of cells are made of an alkaline electrolyte (potassium hydroxide). As a result, these cells achieve much higher capacity and lower internal resistance than standard batteries.

Batteries 14 – general and detailed parameters that should be known

In the terms of physicochemistry, the most important parameters of batteries are the battery type and voltage. As for R14 batteries, they can be zinc-carbon and alkaline, but in each case their sizes are identical or almost identical (diameter: 24.9-26.2mm; length: 50mm). The weight of one R14 battery should not exceed 70 grams. Another important parameter of the battery, the rated voltage, will always be 1.5V - both for the alkaline and standard variants.

When we need batteries for an electrical device, e.g. R14 batteries, we usually take any, possibly sometimes we check the parameters described above. Sometimes, however, it is worth delving into details. Interesting parameters that are worth checking are: actual battery capacity, internal resistance, type of spontaneous discharge and its speed. LR14 alkaline batteries have a nominal capacity of approximately 8000 mAh. The best batteries for professional use have all properties described on the packaging, including resistance, current load, etc.
