2. Partial noun definition
Sealed battery sealed cell: When the battery is working within the specified design range, it remains sealed, but when the internal pressure exceeds the specified value, the gas is allowed to escape through a resettable or non-resettable pressure relief device.
Hermetically sealed cell A battery that does not have a pressure relief device.
Maintenance-free battery A battery that does not require maintenance during use under specified operating conditions.
Battery characteristics and experiment
Battery The amount of electricity that a fully charged battery can provide under specified conditions, usually expressed in Ah (A).
Discharge rate The rate at which the battery discharges in amps.
Mean voltage The average value of the voltage during charging or discharging.
End-of-charge voltage The voltage at which the battery reaches full charge during a specified constant current charge.
The nominal capacity is used to identify the appropriate approximate battery charge for the battery.
Rated capacity The amount of ampere-hours that can be supplied by the manufacturer after the battery is fully charged under specified conditions.
Self-discharge self-discharge When the battery is not connected to an external circuit, the chemical energy is lost due to the self-discharge reaction in the battery.
Overcharge Overcharge Continuous charging after full charge.

Elevator Traction Machine
While there is a wide range of elevators to fit every need, they fall under three basic types: machine-roomless, gearless traction and geared traction.
Traction elevators are the most common type of elevators. Elevator cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced by a counterweight. Sometimes two elevators are built so that their cars always move synchronously in opposite directions, and are each other's counterweight.
