How long will a 12 volt battery provide 100 watts?
Depends on the capacity, the ampere-hours. As watts/volts = current, 100W will mean a current of 8.3A So basically if you had a 83Ah(amp-hours) battery, it would last for one hour. A 41Ah battery would last half an hour. A 166Ah battery would last two hours.
How many batteries would it take to light a 12 volt 100 watt light bulb?
12 volt batteries vary in size. You need to look at the amp hours of a battery and multiply by the voltage. So, a 100 amp hour battery at 12 volts is 1200 watt hours. 30 watt bulb will eat that up at 30 watts and hour. 1200 divided by 30 is 40 hours. Simple huh!? *Something to keep in mind is if your 30 Watt light bulb is rated 30 watts at 12 volts. If it is rated 30 watts at 24 volts, 110 volts or another voltage it will also change the length of time your battery will last.
Is a 10 amp hour battery better than a 12 amp hour battery?
The 12 amp hour battery will last longer under the same load as a 10 amp hour battery. For example if you had a load drawing 2 amps, the 12 Ahr battery would last 6 hours and the 10 Ahr would last 5 hours under ideal conditions.
What does 8Ahmean on a 12 volt battery?
Amp hours is a battery rating. It means that this battery can sustain 1 amp for 8 hours up to 8 amps for 1 hour. Depending on what the current draw is on the load will determine the length of time the battery will last.
How can you know my cardiac pacamker remaining time in ampere-hours when all data i have is 2.75 Volts and I know Volts equals Watts divided by Amp?
A: Pacemaker battery is designed to last years. It only does any work when it is necessary. Your doctor is the best way to analyze the validity of the battery and it is safer that way. I read in a medical journal that most pacemakers last longer then the host. Do not worry about but do see your doctor to make sure.

How long does a 12v 7ah 20hr battery last?

What does 63 whr mean?
It stands for watt-hour. In relationship to batteries, it measures how many watts in an hour a battery can sustain. A 63 watt-hour battery will supply 63 watts for 1 hour, or 6.3 watts for 10 hours or 31.5 watts for 2 hours, etc. It is extremely difficult to determine, from this number, how long your equipment (say, a laptop) will run using a 63 hour battery. The thing for which this number is most useful is battery comparison. A 20 WHr battery will last twice as long as a 10 WHr battery and half as long as a 40 WHr battery and so on.
