How many minutes is two amp hours?
Ampere-hours measures the capacity of a battery. How long such a battery at full capacity lasts depends at what rate energy is taken away. 2 Ah can handle a current of 1 A for 2 hours, 0.1 A for 20 hours, etc.
How many hours or minutes will it take a battery to die?
It depends on how much energy what your using calls for. ._.
What does 85 Wh mean?
The letters Wh means watt hours. this is how many hours of power the battery can store. The larger the number, the more power the battery can store. This is important for laptops, smartphones, and tablets. or Another way to measure the capacity of the battery is in watt-hours(wh). wh is calculated by multiplying the number of Amps with the battery voltage.

What does RC mean on 12volt car batteries?
Reserve Capacity. The number of minutes a battery can maintain a useful voltage under a 25 amp discharge. Reserve capacity is often a truer test of battery life than amp hours.

Capacity of a battery?
ampere hours
Can you detect the end of the life of a car battery?
You can do a load test on a battery and compare it to the reserve capacity and cold cranking amps. If it is lower then the ratings then the battery is going bad. Keep in mind that the battery must be charged to its maximum capacity to have an accurate test. Trickle charge on 2 to 6 amps for approx. 6 hours then test battery
How long can you drive a car with a fully charged battery but the alternator might be bad?
That will depend on the capacity of the battery and the amount of electrical loads. could be 15 minutes or a couple of hours.
How long do I have to charge rc airplane batteries before it will fly?
To charge a rc battery,first find out the battery capacity,Then the out put of the charger. Divide those together and times by 1.5 to get the hours and minutes to charge the battery. Note .15 is 10 minutes.
What is the battery charge time of the VAIO Z series Notebook PC?
Sony estimates that the battery charge time is two to six hours for the standard capacity battery, and three to nine hours for the large capacity battery.
What is mAh?
mAh = milliamp hours, which is battery capacity
How many amp hours in BXT-65-650 battery?
Difficult. The manufacturers of car batteries have become extremely coy about the performance parameters of their products, probably because they don't want to be forced to meet them by a court. However, I would suspect that it would be in the vicinity of 30-40 ampere hours. That means that it can deliver 30-40 amps for one hour, so at a voltage of 13.2 volts, that means 396 - 528 watt-hours, ignoring the fact that the voltage decreases as it discharges. The "Cold cranking" current is a red herring...that is just the current it can supply for a short time, limited by the internal resistance of the battery. <<>> Battery manufactures have gone to a Reserve Capacity rating which is more realistic than using the Amp-Hour rating. Reserve capacity is the number of minutes that a battery can maintain a useful voltage under a 25 ampere discharge at a temperature of 25 degrees C. To maintain a high RC number a battery requires higher quality cell materials. The RC rating of a BXT-65-650 is 130. To convert RCR (Reserve Capacity Rating) to Ampere-Hours at the 25 amp rate, multiply RCR by .4167.
How many hours a 850amps battery can run a 2000 watts motor?
It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.
How long does it take to charge AAA batteries?
There are a few variables to this question that are not stated. The type of battery for example lithium of alkaline, the capacity of the battery in amp hours, the higher the capacity the longer the charge rate and the capacity output of the battery charger are a few to mention.
How long does a power king battery last?
No set answer to that, it depends on the size/capacity of the battery and what it's powering.
