A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. In contrast, starter batteries are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity. 
Coiled tubing refers to a continuous length of small-diameter steel pipe and related surface equipment as well as associated drilling, completion and workover, or remediation, techniques. Coiled tubing oilfield technology was initially developed for working on live, producing wells.
Coiled tubing technology is frequently used to deploy tools and materials through production tubing or casing while remedial work is performed on producing wells. Coiled tubing fulfills three key requirements for downhole operations on live wells by providing a dynamic seal between the formation pressure and the surface, a continuous conduit for fluid conveyance and a method for running this conduit in and out of a pressurized well.
Coiled tubing strength and rigidity, combined with its capability to circulate treatment fluids, offer distinct advantages in workover operations. In addition to drilling and completion operations, oil and gas companies are using coiled tubing to help fish for lost equipment and for conveying well logging tools.
The amorphous is a non-crystal substance created by rapidly freezing liquids of high temperature. Because there is no rule of atomic arrangement, the energy loss (hysteresis loss) is small when the flux of magnetic induction passes the iron core. In addition, eddy current loss is decreased because the thickness is approximately 0.03 mm, which is about 1/10 comparing with silicon steel. Therefore, the no load loss (eddy current loss and hysteresis loss) can be decreased to about 1/5 of silicon steel's.
An amorphous core transformer is a highly efficient electrical transformer, which has a magnetic core comprised of ferromagnetic amorphous metal alloyed with a glass former. This ribbon of steel is wound to form the transformers core. The materials used in amorphous core transformers have high magnetic susceptibility, low coercivity and high electrical resistance.
Description
Traditional hearing aid batteries were produced using trace amounts of mercury to assist with conductivity and stabilize internal components, but mercury is no longer used in hearing aid batteries. Zinc-air batteries remain stable for up to three years when stored in a room temperature, dry environment.

Description
A flexible alternating current transmission system (FACTS) is a system composed of static equipment used for the AC transmission of electrical energy. It is meant to enhance controllability and increase power transfer capability of the network. It is generally a power electronics-based system.
FACTS is defined by the IEEE as "a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase power transfer capability."
