You could put a know resistive load on the battery and then monitor the voltage across the load until the battery was at zero volts. Using Ohm's Law you can calculate the current at any time. Current = Voltage / Resistance. You can multiply the average current times the number of hours for the battery to go to zero.

How you calculate ups backup time for 4 fan?
For the backup time for 4 fans. First we required battery AH (battery amper) and battery volts & and and ups ratings. then we calculate back time .
How do you calculate the charge a car battery can hold?
You really can't calculate that, it's determined at manufacture. It'll be stated on the battery casing. Look for something saying Ah, Ampere hours.
How long will a 4100 Ah battery last?
There is a fairly simple method that can be used to calculate battery life, but you would have to know the power consumption of the device your 4100 Ah battery is powering up. If you hit the web and check out the DigiKey Battery Life Calculator, you can enter the requisite information and get a good idea of the battery life/run time.
Can you replace a battery that is rated at 4ah with a larger ah battery?
Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
Can you use a 12v 7.2 ah battery to replace a 12v 4 ah battery in an alarm system?
Yes
Can I replace a 12v 33ah battery with a 12v 4.5 ah battery for a motorized scooter?
No, it does not have enough capacity (i.e. ah rating).
Describe the difference of V and Ah in a battery?
V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.
Will a 12 volt 75 ah battery charger can be used to charge a 12 volt 150 ah battery?
Yes. In about two to two and a half hours, depending on the condition of the battery.
What type of battery that suits Toyota?
12 Volt 70 AH battery
Can a 15 ah battery can be used to supply 12v to a plc pannel instead of 14 ah battery?
Yes as long as they are both 12 volt batteries.
What type of battery that suits Toyota innova?
12 Volt 70 AH battery
Would a 36V 230 Ah 6hr 335 Ah 20hr traction battery charge on a DC volts24v DCamps20A battery charger?
NO, in order to 'charge' a battery, the charging device must be at a higher voltage than the battery in order for current to flow to the battery.
