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.
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.
as long as its 12 volts.!
Yes as long as it is 12 volts.
a car battery last for about 3-5 years
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.
As long as it's 12 volts and it will hook up it will do fine.
As long as the battery is kept charged then it should last 3-5 years.
a panasonic triple a battery last about 4 hours nonstop.
about a year.
8hrs
Forever.
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.
