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]
The paradox of a charge in a gravitational field is an apparent physical paradox in the context of general relativity. A charged particle at rest in a gravitational field, such as on the surface of the Earth, must be supported by a force to prevent it from falling. According to the equivalence principle, it should be indistinguishable from a ...
At bedtime, Jackson takes back a pillow he said that Elly could keep, Elly’s's Cherry night light burns out, he bites his tongue, and the family cat chooses to sleep with Ella. Throughout the book, there is a running gag where Elly expresses his longing to move to Memphis, believing that life is better there. His mother points out that even ...
A concussion is a mild form of traumatic brain injury, or TBI. It occurs when the skull and brain are rapidly jolted back and forth. This is usually the result of a bump, bang, or blow to the head ...
Trickle charging. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
Exercise. Staying physically active is important to maintain fluid balance in the body and prevent water retention, the experts note. Exercise can also promote fluid loss through sweating ...
A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially ...
Independent testing of Nyobolt’s batteries by what it called a leading global manufacturer found that they can achieve over 4,000 fast-charge cycles, equivalent to 600,000 miles (965,600 ...
