23.75 hours is 23 hours and 45 minutes, so you would need another 15 minutes for 24 hours.
There are 24 hours in a day, no need for a decimal.
To convert from hours to minutes, you need to multiply by 60.
8 hours.
You need to specify the units of 79.88
The Lorex's battery backup lasts for about six hours, after which it will need to be recharged.
This is an informal unit for energy, often used for batteries. mAh = milliampere x hours. If you know how much current you will need (in milliamperes), you can divide the 4400 mAh by the amount of current, to calculate how many hours the battery will last.
Need to see how many amp or watt hours your battery is rated for, many batteries are up to 100 watt hours.your cell phone may hold 1 or so watt hours to give you a comparison. A car battery could maybe charge your phone 500,times before its drained.
A laptop computer has a battery that has a wonderful battery life. As long as you charge your laptop battery for the appropriate amount of time, then you can use your laptop without the need to plug it in for many hours.

To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
how many batteries do you need for shed
(mA of current the circuit draws from the battery when it's running) multiplied by (number of hours you want the circuit to operate from the battery) is equal to the absolute minimum mAh rating the battery must have.
The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).
It takes about 2 - 3 hours for a full charge
Most of the 4.0 and upward Android version does warn the need of a battery replacement after the current battery has had too many discharges.
they're human aren't they? so wouldn't the answer be how many hours of sleep does a human need? and the answer is about 8 hours.
