Get Pricemaximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
Get PriceVoltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
Get PriceBattery Capacity. In a broader sense, the amp hour rating does tell us a little bit about the battery''s capacity. For instance, a battery with a 10 Ah rating will last twice as long as a battery with a 5 Ah rating when used under similar conditions, but it does not mean that it will actually last 10 full hours.
Get PriceThat does not mean the concept is not useful though, as many real world circuits can be modeled using the concept. I''ve seen lab power supplies that have two knobs, one which adjusts voltage, the other adjusts current. ...
