Throughout the 1950s, many engineers had experimented with alkaline batteries, but nobody had been able to develop a longer-running battery which was worth the higher cost of production. Urry, after testing a number of materials, discovered that manganese dioxide and solid zinc worked well coupled with an alkaline substance as an electrolyte .
The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".
The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries (Matchstick for reference). This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.
In 1957, the company sold stock. In 1960, founder P.R. Mallory gave control of the company to his son G. Barron Mallory, who was chairman from 1960 to 1968 and active on the board for many years afterward. The company began manufacturing batteries at plants in Kentucky and Tennessee in 1960 and 1961.
DieHard battery manufacturing afterward returned to Johnson Controls. The DieHard brand is also used on hand tools, power tools, battery chargers, booster cables, power inverters, alkaline batteries, tires, work boots, and the batteries for Craftsman power tools. Battery chargers were initially made by Associated Equipment under the "608" model ...
The origins of the "Remington" name date back to the formation of E. Remington and Sons, a firearms maker founded in 1816. E. Remington & Sons made occasional forays into products other than firearms, such as sewing machines and farm implements—but its most significant side venture was when inventor Christopher Sholes persuaded the firearms company to help him develop the typewriter with the ...
This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.
