To calculate the energy capacity in Watt-hours, you need to know the battery's voltage, measured in Volts, and its charge capacity, measured in amp-hours or milliamp-hours (1000 mAh = 1 Ah). These figures can typically found on any battery's data sheet. Note that charge capacity typical...
In theory, you can calculate the run-time for any of your battery's accessories by dividing the amp-hour rating of the battery by the amp draw of the accessory. You might have to convert from watts first. For instance, if you want to know how long you can bang a 1,000-watt stereo...
Let’s look at an example. If you’re not sure your battery’s amp hours, but you know the watt-hours are 120, and the voltage is 12, you can calculate the amp hours: 100Wh / 12V = 10Ah. How Many Watt Hours in a 100 Ah Lithium Battery? To answer this question, we need to ...
is commonly used in watches, calculators, toys, and different medical devices. These batteries provide long-lasting, reliable power and have a very high weight-to-power ratio. Used in wrist watches and slim, compact thermometers, this battery is practically weightless while providing hours of use...

discussing Ah (ampere-hours) and Wh (watt-hours), we got a ton of questions about the longevity of batteries. The question“How long does a battery last?”was a predominant one. To help everybody trying to calculate how long will a battery last, we have created aBattery Life Calculator...
Ideally, I would like to be able to set this camera trap out for a full week without replacing the battery, but I can manage twice a week. I'm realizing I have no idea how to even calculate how much power I am using with this set up, let alone what size battery will charge the...
To calculate the life of a lithium-ion battery, you can use the following formula: Life (in cycles) = (Capacity x 100) / (Discharge rate x Depth of discharge) In this formula, capacity is the rated capacity of the battery in amp-hours (Ah), discharge rate is the rate at which the...
Let’s use the kVA to amps calculator above to answer that: As we can see, a 65 kVa generator at 220 V can create an almost 300 Amp current. Example 2: What Is 1 kVA In Amps? To calculate the amps for yourself, it’s useful to know what is 1 kVA in amps. Of course, this ...
Battery Discharge As we all know, you can't fly with a LiPo battery until it is completely flat. This is because there is a limit on how many amp-hours you can discharge before the battery isn't able to be recharged. What this means is that the effective capacity of a LiPo is only...
