A dry cell is a type of electric battery, commonly used for portable electrical devices. Unlike wet cell batteries, which have a liquid electrolyte, dry cells use an electrolyte in the form of a paste, and are thus less susceptible to leakage . The dry cell was developed in 1886 by the German scientist Carl Gassner, after development of wet ...
Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell; insulated from it, the metallic top cap ...
Power. 8 hours of battery life with standard 6-cell battery. Dimensions. 42.01 x 27.61 x 3.6 cm. Mass. 2.88 kg (6.35 lb) The Dell 1764 is a laptop computer designed by Dell. At the time of its introduction, it was noted for a fast processor and good sound, [1] [2] a medium hard disk drive and a release price of 679 USD .
The lithium iron phosphate battery ( LiFePO. 4 battery) or LFP battery ( lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate ( LiFePO. 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and ...
A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [ 5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar) pressure. [ 6] The nickel–hydrogen battery was patented in ...
A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate ( Zn ...
On August 19, 2010, Dell Europe announced the introduction of the Dell Mini 1018. This new Dell Mini features the Atom N455 CPU which supports DDR3 memory. Design has also been tweaked and stated specs include 7+ hours of battery life on the 6-cell battery (unconfirmed). As of January 2011, the model has been made available in Asia.
