A typical shock collar. Shock collar used on a riot police dog in 2004 in Würzburg.Two years later, [1] Germany banned the use of shock collars, even by police. [2]A shock collar or remote training collar, also known as an e-collar, Ecollar, or electronic collar, is a type of training collar that delivers shocks to the neck of a dog [3] to change behavior.
A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
A lighted collar (or collar light, dog light) is a collar that emits light in order to make a dog more visible in the dark to their owners and more importantly, nearby motorists. It is not designed to help a dog see at night, as it is well documented that dogs have very good vision in low light conditions.
Jungner's work was largely unknown in the US until the 1940s, when nickel–cadmium batteries went into production there. A 50 volt nickel–iron battery was the main D.C. power supply in the World War II German V-2 rocket, together with two 16 volt batteries which powered the four gyroscopes (turbine powered generators supplied A.C. for its ...
The alkaline electrolyte (commonly KOH) is not consumed in this reaction and therefore its specific gravity, unlike in lead–acid batteries, is not a guide to its state of charge. When Jungner built the first Ni–Cd batteries, he used nickel oxide in the positive electrode, and iron and cadmium materials in the negative.
An Australian Kelpie wearing a plastic Elizabethan collar to help an eye infection heal. An Elizabethan collar, E collar, pet ruff or pet cone (sometimes humorously called a treat funnel, lamp-shade, radar dish, dog-saver, collar cone, or cone of shame) is a protective medical device worn by an animal, usually a cat or dog.
Rechargeable lithium metal battery, a rechargeable counterpart to the lithium metal battery; Lithium-ion battery, a rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging Aqueous lithium-ion battery; Lithium-ion flow battery; Lithium ion manganese oxide battery
The cost of lithium batteries fell drastically during the 2010s and many small consumer devices now have non-consumer-replaceable lithium batteries as a result. Lithium batteries produce a higher voltage (3.2–3.7 V nominal), and are thus not a drop-in replacement for AA (alkaline or NiMh) batteries without circuitry to reduce voltage.
