C/20 is the formula most commonly used to describe a battery according to its amp hour rating; for instance a 400Ahr rated battery means that a 20 amp load placed upon the battery delivers at that rate of energy for 20 hours upon reaching the manufacturer's per cell rating, usually about 1.7 volts or 10 volts for a dead, discharged battery. There are different discharge or load ratings such as a 10 hour or 100 hour rating resulting in a different Amp Hour rating for the very same battery. A battery is an electrical potential energy source whose capacity (amount of energy density delivered over time) is determined by the rate/time over which the battery will deliver a set rate of load/discharge. The lesser the load, the longer the rate, the higher the load the shorter the rate.

What is the amp hour of a 12 volt battery for 23 watts power for a time of 4 hours?
To calculate the amp-hour rating, first divide the power (23 watts) by the voltage (12 volts) to get the current in amps (1.92 A). Then, multiply the current by the time (4 hours) to get 7.68 amp-hours. Therefore, a 12-volt battery powering a 23-watt load for 4 hours would require a battery with a capacity of at least 7.68 amp-hours.
How many amp hours does a deep cycle battery typically have?
A typical deep cycle battery usually has amp-hour ratings ranging from 50 to 200 amp-hours.
What is the amp hours on a AAA battery?
1250 milliamp hours.
How long can a 80 amp battery last when you use 0.5 amp?
To determine how long an 80 amp-hour battery can last when drawing 0.5 amps, you can use the formula: time (in hours) = battery capacity (in amp-hours) / load current (in amps). So, 80 amp-hours ÷ 0.5 amps = 160 hours. Therefore, the battery can last approximately 160 hours under that load, assuming ideal conditions and no significant losses.
What is the typical amp hour rating of a marine battery?
The typical amp hour rating of a marine battery is usually between 50 to 200 amp hours.
How many amp hours are typically found in a deep cycle battery?
Deep cycle batteries typically have amp hour ratings ranging from 50 to 200 amp hours, depending on the size and capacity of the battery.
What is the amp rating for?
Total battery amp hours of the battery, divided by the amp draw, equals the life of the battery.Example=200 amp hours, divided by 5 amps, equals 40.00 hours.There are many different factors. This is based on constant draw.
How do you calculate 24 volt battery life with a continuous 1500 watt draw?
You'll need to know the capacity of the battery. Current requirement for 1500 watt at 24 V is: 1500/24= 62.5 amps. If the battery has 62.5 amp hours it would in theory last one hour. if the battery had something like 80 amp hours, it'd last for about one hour 20 minutes.
How long would an 8 Amp hr battery last with 75mA current draw?
An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.
What is a amp hour?
It is one amp current used over one hour. A ten amp hour battery can supply 1/2 an amp for 20 hours, 1 amp for 10 hours, etc.
What do amp hr mean on a 12 volt battery?
It is a rating for the capacity of the battery to power a load. A battery rated at 15 amp/hrs has the ability to power a load of 15 amps for 1 hour, or 1 amp for 15 hours, or any combination of the two numbers. Example, 2 amps for 7.5 hours, 3 amps for 5 hours or 5 amps for 3 hours etc.
How many amp hours is a car battery?
Depends on the battery you buy. They come in different CCA.
