2. Molten-salt battery - Wikipedia

   en.wikipedia.org/wiki/Molten-salt_battery

   After shutdown a fully charged battery pack loses enough energy to cool and solidify in five-to-seven days depending on the amount of insulation. [citation needed] Sodium metal chloride batteries are very safe; a thermal runaway can be activated only by piercing the battery and also, in this unlikely event, no fire or explosion will be ...

3. Northern Pacific Railway locomotives - Wikipedia

   en.wikipedia.org/wiki/Northern_Pacific_Railway...

   Below is a table of information for the Northern Pacific Railway’s steam roster with a symbol, Whyte notation, common name and notes. (The notes were compiled by Richard Boyland and Wes Barris and first posted May 30, 1991, to the electronic newsgroup rec.railroad.) Included is a breakdown of the Northern Pacific classes, along with the date ...

4. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.

5. Computers and Intractability - Wikipedia

   Computers and Intractability: A Guide to the Theory of NP-Completeness is a textbook by Michael Garey and David S. Johnson. [1] It was the first book exclusively on the theory of NP-completeness and computational intractability . [ 2 ]

6. Depth of discharge - Wikipedia

   en.wikipedia.org/wiki/Depth_of_discharge

   Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.

7. TI SR-50 - Wikipedia

   en.wikipedia.org/wiki/TI_SR-50

   SR-50 (1974) Printed circuit board. Data code 035: 3rd week 1975. The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. . It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other featur

8. Lithium-titanate battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-titanate_battery

   A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode.This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.

9. Nine-volt battery - Wikipedia

   en.wikipedia.org/wiki/Nine-volt_battery

   The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.
