The voltage doesn't enter into the issue.

If the current draw of your battery-powered equipment is 1 Ampere, the battery will last 700 years.

If your equipment draws 1/2 Ampere, the battery will last 1,400 hours.

If your equipment draws 2 Amperes, the battery will last 350 hours.

And so on.

CorrectionA 700 AH battery will THEORETICALLY last 70 hours at 1 amp current draw.

A 700 AH battery will THEORETICALLY last 140 hours at 1/2 amp current draw.

A 700 AH battery will THEORETICALLY last 35 hours at 1/2 amp current draw.

The theoretical capacity of a battery is always greater than the actual capacity; electrical energy is released in the form of heat inside the battery.

How long will your 100ah battery last with a 20Watt light on?

To determine how long a 100Ah battery will last with a 20W light, you first convert the wattage to amps. Using the formula: Amps = Watts / Volts, and assuming a 12V battery, the light draws about 1.67A (20W / 12V). Therefore, a 100Ah battery would last approximately 60 hours (100Ah / 1.67A) under ideal conditions, without accounting for factors such as battery efficiency and depth of discharge.

How long will a 12 volt battery provide 100 watts?

To calculate the duration a 12 volt battery will provide 100 watts of power, you can use the formula P = V x I, where P is the power (100 watts), V is the voltage (12 volts), and I is the current. Rearranging the formula to solve for current, we get I = P / V. Plugging in the values gives I = 100 watts / 12 volts = 8.33 amps. The battery's capacity, typically measured in ampere-hours (Ah), can then be used to determine how long the battery will last. If the battery capacity is say 50Ah, you can divide the capacity by the current to find how long the battery will last: 50Ah / 8.33A = approximately 6 hours.

What does 53Whr mean in terms of battery life for a new laptop?

"Whr" is an invalid unit. The correct unit is "Wh" which is the SI unit of power multiplied by time, typically hours, but minutes and seconds are equally valid as in "Wattminutes" and "Wattseconds." A simple answer is that a 53Wh battery will last half as long as a 106Wh battery. But what does that really mean? To answer the question more fully, batteries are typically rated in Ah or Amphours which means a battery with a rating of 50 Amphours (like a typical car battery) can deliver 50 Amps for one hour, 10 Amps for 5 hours, etc. Note that this is strictly a current over time rating without regard to the battery voltage. However, Ah is NOT the amount of power a battery can supply. Power = Amps x Volts = Watts. However, Watts are a RATE of power being supplied, not how much in total. To signify an AMOUNT of power, you need to add time. Thus, Watts x time = total amount of power, or more correctly, energy supplied. So, taking your question of "What does 53Whr mean in terms of battery life for a new laptop?", we can answer that in terms of how long the battery charge will last because all batteries fundamentally suppy x amount of current for x amount of time regardless of what the battery voltage is. But we need to know the voltage in order to determine how much energy a battery can supply. If we work backwards, and take 53Wh, we are starting with the total amount of energy the battery can supply. But that does not give any real idea as to HOW LONG the battery will run the computer. To know how long the battery will last, we need to know just a few of several possible things: the battery's Amphour rating and the current drawn by the computer or, it's Wattage (Watts drawn) and the battery's Wh rating. The latter one you know. Or, it's voltage and Amphour ratings. From these we can convert back and forth to any other unit(s). Since you only have the battery's Wh rating, to figure out the battery's Amphour rating, one must know the battery voltage because Watts = Amps x Volts. There are multiple ways to approach this question depending on what units you are given but we can really only make an estimate as the amount of power modern computers use depends on what you are doing. Like is the backlight on high or low? Or, are you typing a note, or playing a high-power game, or watching a DVD etc. etc... . The only way to mostly answer your question verbatim is to make some assumptions, get an answer, and show you how one calculates the run time. Then, you would have to use actual values to get a "real" answer. Here are three paths leading to the same answer: First, let's assume that, Battery rating = 53Wh, and Laptop nameplate power is 35 Watts. We know the laptop will use anywhere from 35W to maybe 1W so we take the worst case of 35W. Very simply, Wh = Watts x hours. Thus, hours = Wh ÷ Watts. So 53Wh ÷ 35W = 1.51 hours or 91 minutes. That's the simplest way. But, what if instead the laptop's label says 2.92 Amps @ 12 Volts? In this case, we know the battery voltage, and the laptop's current comsumption, but we need to convert that into energy which is what the battery provides, and is what Watthours are. Using Ohm's law (sorry if this is getting too technical), Amps x Volts = Watts. Using our assumed numbers, 12 Volts x 2.92 Amps = 35W. Appying the first scenario, the run time would then be the battery's 53Wh ÷ 35W = 1.51 hours, the same time we calculated above. As long as you know the battery voltage, and either Watts consumed, or the current (Amps) drawn, you can convert into Wh and determine how long the battery should run. Finally, a third way to get the same answer: Again, assuming the battery is 12 Volts, and is rated at 53Wh, we can say 53Wh ÷ 12V = 4.42 Amphours (Ah). Assuming the same current draw of the laptop of 2.92 Amps, we can calculate 4.42Ah ÷ 2.92Amps = 1.51 hours, again, the same time. Interestingly, you asked about a "new" laptop. As the battery ages, it's Amphour and thus Watthour rating will slowly decline until it's energy capacity becomes low enough to become a pain in the butt. Then, it's time for a new battery!


How long would it take to charge a car battery with a 6 volt motor?

The car battery has 12 volts; you need MORE than that to charge it. You can't charge it with 6 volts, unless you somehow raise the voltage. In that case, how long it takes to charge the car battery will depend on the capacity of the charging device. Usually a few hours.
