Temperature Derating: Reducing the output power of a battery charger or power supply with increasing temperature to maintain reliable operation.
Thermal Protection: A protection circuit which prevents equipment from damaged by temperatures that the equipment is not designed to operate in.
Transient Recovery Time: The time required for an output voltage to be within specified limits after a specified change in input or load.
Taper Charge: A charging technique delivering a moderately high rate charging current when the battery is at a low state of charge and tapering the charging current to lower rates as the battery is charged.
Vent: A normally sealed mechanism allowing for the controlled and intentional release of gases.
Volt: SI unit for the measurement of voltage, defined as joules (energy) per unit of electrical charge(coulombs). Voltage in laymen terms is commonly referred to as the amount of electrical pressure available to produce a current flow through a given resistance.
Voltage Drop: The loss of voltage between two points due to the internal impedance or resistance of the interconnections.
Voltmeter: An instrument used to measure voltage. The unit for the measurement of voltage is volts.
Waterproof: Designed such that water and moisture will not enter the enclosure under specified test conditions.
Watt: SI unit for the measurement of power. For DC, the amount of power is obtained by multiplying volts times amperes.
